If the software is modified by someone else and passed on, we -want its recipients to know that what they have is not the original, so -that any problems introduced by others will not reflect on the original -authors' reputations. - - Finally, any free program is threatened constantly by software -patents. We wish to avoid the danger that redistributors of a free -program will individually obtain patent licenses, in effect making the -program proprietary. To prevent this, we have made it clear that any -patent must be licensed for everyone's free use or not licensed at all. - - The precise terms and conditions for copying, distribution and -modification follow. - - GNU GENERAL PUBLIC LICENSE - TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION - - 0. This License applies to any program or other work which contains -a notice placed by the copyright holder saying it may be distributed -under the terms of this General Public License. The "Program", below, -refers to any such program or work, and a "work based on the Program" -means either the Program or any derivative work under copyright law: -that is to say, a work containing the Program or a portion of it, -either verbatim or with modifications and/or translated into another -language. (Hereinafter, translation is included without limitation in -the term "modification".) Each licensee is addressed as "you". - -Activities other than copying, distribution and modification are not -covered by this License; they are outside its scope. The act of -running the Program is not restricted, and the output from the Program -is covered only if its contents constitute a work based on the -Program (independent of having been made by running the Program). -Whether that is true depends on what the Program does. - - 1. You may copy and distribute verbatim copies of the Program's -source code as you receive it, in any medium, provided that you -conspicuously and appropriately publish on each copy an appropriate -copyright notice and disclaimer of warranty; keep intact all the -notices that refer to this License and to the absence of any warranty; -and give any other recipients of the Program a copy of this License -along with the Program. - -You may charge a fee for the physical act of transferring a copy, and -you may at your option offer warranty protection in exchange for a fee. - - 2. You may modify your copy or copies of the Program or any portion -of it, thus forming a work based on the Program, and copy and -distribute such modifications or work under the terms of Section 1 -above, provided that you also meet all of these conditions: - - a) You must cause the modified files to carry prominent notices - stating that you changed the files and the date of any change. - - b) You must cause any work that you distribute or publish, that in - whole or in part contains or is derived from the Program or any - part thereof, to be licensed as a whole at no charge to all third - parties under the terms of this License. - - c) If the modified program normally reads commands interactively - when run, you must cause it, when started running for such - interactive use in the most ordinary way, to print or display an - announcement including an appropriate copyright notice and a - notice that there is no warranty (or else, saying that you provide - a warranty) and that users may redistribute the program under - these conditions, and telling the user how to view a copy of this - License. (Exception: if the Program itself is interactive but - does not normally print such an announcement, your work based on - the Program is not required to print an announcement.) - -These requirements apply to the modified work as a whole. If -identifiable sections of that work are not derived from the Program, -and can be reasonably considered independent and separate works in -themselves, then this License, and its terms, do not apply to those -sections when you distribute them as separate works. But when you -distribute the same sections as part of a whole which is a work based -on the Program, the distribution of the whole must be on the terms of -this License, whose permissions for other licensees extend to the -entire whole, and thus to each and every part regardless of who wrote it. - -Thus, it is not the intent of this section to claim rights or contest -your rights to work written entirely by you; rather, the intent is to -exercise the right to control the distribution of derivative or -collective works based on the Program. - -In addition, mere aggregation of another work not based on the Program -with the Program (or with a work based on the Program) on a volume of -a storage or distribution medium does not bring the other work under -the scope of this License. - - 3. You may copy and distribute the Program (or a work based on it, -under Section 2) in object code or executable form under the terms of -Sections 1 and 2 above provided that you also do one of the following: - - a) Accompany it with the complete corresponding machine-readable - source code, which must be distributed under the terms of Sections - 1 and 2 above on a medium customarily used for software interchange; or, - - b) Accompany it with a written offer, valid for at least three - years, to give any third party, for a charge no more than your - cost of physically performing source distribution, a complete - machine-readable copy of the corresponding source code, to be - distributed under the terms of Sections 1 and 2 above on a medium - customarily used for software interchange; or, - - c) Accompany it with the information you received as to the offer - to distribute corresponding source code. (This alternative is - allowed only for noncommercial distribution and only if you - received the program in object code or executable form with such - an offer, in accord with Subsection b above.) - -The source code for a work means the preferred form of the work for -making modifications to it. For an executable work, complete source -code means all the source code for all modules it contains, plus any -associated interface definition files, plus the scripts used to -control compilation and installation of the executable. However, as a -special exception, the source code distributed need not include -anything that is normally distributed (in either source or binary -form) with the major components (compiler, kernel, and so on) of the -operating system on which the executable runs, unless that component -itself accompanies the executable. - -If distribution of executable or object code is made by offering -access to copy from a designated place, then offering equivalent -access to copy the source code from the same place counts as -distribution of the source code, even though third parties are not -compelled to copy the source along with the object code. - - 4. You may not copy, modify, sublicense, or distribute the Program -except as expressly provided under this License. Any attempt -otherwise to copy, modify, sublicense or distribute the Program is -void, and will automatically terminate your rights under this License. -However, parties who have received copies, or rights, from you under -this License will not have their licenses terminated so long as such -parties remain in full compliance. - - 5. You are not required to accept this License, since you have not -signed it. However, nothing else grants you permission to modify or -distribute the Program or its derivative works. These actions are -prohibited by law if you do not accept this License. Therefore, by -modifying or distributing the Program (or any work based on the -Program), you indicate your acceptance of this License to do so, and -all its terms and conditions for copying, distributing or modifying -the Program or works based on it. - - 6. Each time you redistribute the Program (or any work based on the -Program), the recipient automatically receives a license from the -original licensor to copy, distribute or modify the Program subject to -these terms and conditions. You may not impose any further -restrictions on the recipients' exercise of the rights granted herein. -You are not responsible for enforcing compliance by third parties to -this License. - - 7. If, as a consequence of a court judgment or allegation of patent -infringement or for any other reason (not limited to patent issues), -conditions are imposed on you (whether by court order, agreement or -otherwise) that contradict the conditions of this License, they do not -excuse you from the conditions of this License. If you cannot -distribute so as to satisfy simultaneously your obligations under this -License and any other pertinent obligations, then as a consequence you -may not distribute the Program at all. For example, if a patent -license would not permit royalty-free redistribution of the Program by -all those who receive copies directly or indirectly through you, then -the only way you could satisfy both it and this License would be to -refrain entirely from distribution of the Program. - -If any portion of this section is held invalid or unenforceable under -any particular circumstance, the balance of the section is intended to -apply and the section as a whole is intended to apply in other -circumstances. - -It is not the purpose of this section to induce you to infringe any -patents or other property right claims or to contest validity of any -such claims; this section has the sole purpose of protecting the -integrity of the free software distribution system, which is -implemented by public license practices. Many people have made -generous contributions to the wide range of software distributed -through that system in reliance on consistent application of that -system; it is up to the author/donor to decide if he or she is willing -to distribute software through any other system and a licensee cannot -impose that choice. - -This section is intended to make thoroughly clear what is believed to -be a consequence of the rest of this License. - - 8. If the distribution and/or use of the Program is restricted in -certain countries either by patents or by copyrighted interfaces, the -original copyright holder who places the Program under this License -may add an explicit geographical distribution limitation excluding -those countries, so that distribution is permitted only in or among -countries not thus excluded. In such case, this License incorporates -the limitation as if written in the body of this License. - - 9. The Free Software Foundation may publish revised and/or new versions -of the General Public License from time to time. Such new versions will -be similar in spirit to the present version, but may differ in detail to -address new problems or concerns. - -Each version is given a distinguishing version number. If the Program -specifies a version number of this License which applies to it and "any -later version", you have the option of following the terms and conditions -either of that version or of any later version published by the Free -Software Foundation. If the Program does not specify a version number of -this License, you may choose any version ever published by the Free Software -Foundation. - - 10. If you wish to incorporate parts of the Program into other free -programs whose distribution conditions are different, write to the author -to ask for permission. For software which is copyrighted by the Free -Software Foundation, write to the Free Software Foundation; we sometimes -make exceptions for this. Our decision will be guided by the two goals -of preserving the free status of all derivatives of our free software and -of promoting the sharing and reuse of software generally. - - NO WARRANTY - - 11.

It is safest -to attach them to the start of each source file to most effectively -convey the exclusion of warranty; and each file should have at least -the "copyright" line and a pointer to where the full notice is found. - - - Copyright (C) - - This program is free software; you can redistribute it and/or modify - it under the terms of the GNU General Public License as published by - the Free Software Foundation; either version 2 of the License, or - (at your option) any later version. - - This program is distributed in the hope that it will be useful, - but WITHOUT ANY WARRANTY; without even the implied warranty of - MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.

Of course, the commands you use may -be called something other than `show w' and `show c'; they could even be -mouse-clicks or menu items--whatever suits your program. - -You should also get your employer (if you work as a programmer) or your -school, if any, to sign a "copyright disclaimer" for the program, if -necessary.

It also counts - as the successor of the GNU Library Public License, version 2, hence - the version number 2.1.] - - Preamble - - The licenses for most software are designed to take away your -freedom to share and change it. By contrast, the GNU General Public -Licenses are intended to guarantee your freedom to share and change -free software--to make sure the software is free for all its users. - - This license, the Lesser General Public License, applies to some -specially designated software packages--typically libraries--of the -Free Software Foundation and other authors who decide to use it. You -can use it too, but we suggest you first think carefully about whether -this license or the ordinary General Public License is the better -strategy to use in any particular case, based on the explanations below. - - When we speak of free software, we are referring to freedom of use, -not price. Our General Public Licenses are designed to make sure that -you have the freedom to distribute copies of free software (and charge -for this service if you wish); that you receive source code or can get -it if you want it; that you can change the software and use pieces of -it in new free programs; and that you are informed that you can do -these things. - - To protect your rights, we need to make restrictions that forbid -distributors to deny you these rights or to ask you to surrender these -rights. These restrictions translate to certain responsibilities for -you if you distribute copies of the library or if you modify it. - - For example, if you distribute copies of the library, whether gratis -or for a fee, you must give the recipients all the rights that we gave -you. You must make sure that they, too, receive or can get the source -code. If you link other code with the library, you must provide -complete object files to the recipients, so that they can relink them -with the library after making changes to the library and recompiling -it. And you must show them these terms so they know their rights. - - We protect your rights with a two-step method: (1) we copyright the -library, and (2) we offer you this license, which gives you legal -permission to copy, distribute and/or modify the library. - - To protect each distributor, we want to make it very clear that -there is no warranty for the free library. Also, if the library is -modified by someone else and passed on, the recipients should know -that what they have is not the original version, so that the original -author's reputation will not be affected by problems that might be -introduced by others. - - Finally, software patents pose a constant threat to the existence of -any free program. We wish to make sure that a company cannot -effectively restrict the users of a free program by obtaining a -restrictive license from a patent holder. Therefore, we insist that -any patent license obtained for a version of the library must be -consistent with the full freedom of use specified in this license. - - Most GNU software, including some libraries, is covered by the -ordinary GNU General Public License. This license, the GNU Lesser -General Public License, applies to certain designated libraries, and -is quite different from the ordinary General Public License. We use -this license for certain libraries in order to permit linking those -libraries into non-free programs. - - When a program is linked with a library, whether statically or using -a shared library, the combination of the two is legally speaking a -combined work, a derivative of the original library. The ordinary -General Public License therefore permits such linking only if the -entire combination fits its criteria of freedom. The Lesser General -Public License permits more lax criteria for linking other code with -the library. - - We call this license the "Lesser" General Public License because it -does Less to protect the user's freedom than the ordinary General -Public License. It also provides other free software developers Less -of an advantage over competing non-free programs. These disadvantages -are the reason we use the ordinary General Public License for many -libraries. However, the Lesser license provides advantages in certain -special circumstances. - - For example, on rare occasions, there may be a special need to -encourage the widest possible use of a certain library, so that it becomes -a de-facto standard. To achieve this, non-free programs must be -allowed to use the library. A more frequent case is that a free -library does the same job as widely used non-free libraries. In this -case, there is little to gain by limiting the free library to free -software only, so we use the Lesser General Public License. - - In other cases, permission to use a particular library in non-free -programs enables a greater number of people to use a large body of -free software. For example, permission to use the GNU C Library in -non-free programs enables many more people to use the whole GNU -operating system, as well as its variant, the GNU/Linux operating -system. - - Although the Lesser General Public License is Less protective of the -users' freedom, it does ensure that the user of a program that is -linked with the Library has the freedom and the wherewithal to run -that program using a modified version of the Library. - - The precise terms and conditions for copying, distribution and -modification follow. Pay close attention to the difference between a -"work based on the library" and a "work that uses the library". The -former contains code derived from the library, whereas the latter must -be combined with the library in order to run. - - GNU LESSER GENERAL PUBLIC LICENSE - TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION - - 0. This License Agreement applies to any software library or other -program which contains a notice placed by the copyright holder or -other authorized party saying it may be distributed under the terms of -this Lesser General Public License (also called "this License"). -Each licensee is addressed as "you". - - A "library" means a collection of software functions and/or data -prepared so as to be conveniently linked with application programs -(which use some of those functions and data) to form executables. - - The "Library", below, refers to any such software library or work -which has been distributed under these terms. A "work based on the -Library" means either the Library or any derivative work under -copyright law: that is to say, a work containing the Library or a -portion of it, either verbatim or with modifications and/or translated -straightforwardly into another language. (Hereinafter, translation is -included without limitation in the term "modification".) - - "Source code" for a work means the preferred form of the work for -making modifications to it. For a library, complete source code means -all the source code for all modules it contains, plus any associated -interface definition files, plus the scripts used to control compilation -and installation of the library. - - Activities other than copying, distribution and modification are not -covered by this License; they are outside its scope. The act of -running a program using the Library is not restricted, and output from -such a program is covered only if its contents constitute a work based -on the Library (independent of the use of the Library in a tool for -writing it). Whether that is true depends on what the Library does -and what the program that uses the Library does. - - 1. You may copy and distribute verbatim copies of the Library's -complete source code as you receive it, in any medium, provided that -you conspicuously and appropriately publish on each copy an -appropriate copyright notice and disclaimer of warranty; keep intact -all the notices that refer to this License and to the absence of any -warranty; and distribute a copy of this License along with the -Library. - - You may charge a fee for the physical act of transferring a copy, -and you may at your option offer warranty protection in exchange for a -fee. - - 2. You may modify your copy or copies of the Library or any portion -of it, thus forming a work based on the Library, and copy and -distribute such modifications or work under the terms of Section 1 -above, provided that you also meet all of these conditions: - - a) The modified work must itself be a software library. - - b) You must cause the files modified to carry prominent notices - stating that you changed the files and the date of any change. - - c) You must cause the whole of the work to be licensed at no - charge to all third parties under the terms of this License. - - d) If a facility in the modified Library refers to a function or a - table of data to be supplied by an application program that uses - the facility, other than as an argument passed when the facility - is invoked, then you must make a good faith effort to ensure that, - in the event an application does not supply such function or - table, the facility still operates, and performs whatever part of - its purpose remains meaningful. - - (For example, a function in a library to compute square roots has - a purpose that is entirely well-defined independent of the - application. Therefore, Subsection 2d requires that any - application-supplied function or table used by this function must - be optional: if the application does not supply it, the square - root function must still compute square roots.) - -These requirements apply to the modified work as a whole. If -identifiable sections of that work are not derived from the Library, -and can be reasonably considered independent and separate works in -themselves, then this License, and its terms, do not apply to those -sections when you distribute them as separate works. But when you -distribute the same sections as part of a whole which is a work based -on the Library, the distribution of the whole must be on the terms of -this License, whose permissions for other licensees extend to the -entire whole, and thus to each and every part regardless of who wrote -it. - -Thus, it is not the intent of this section to claim rights or contest -your rights to work written entirely by you; rather, the intent is to -exercise the right to control the distribution of derivative or -collective works based on the Library. - -In addition, mere aggregation of another work not based on the Library -with the Library (or with a work based on the Library) on a volume of -a storage or distribution medium does not bring the other work under -the scope of this License. - - 3. You may opt to apply the terms of the ordinary GNU General Public -License instead of this License to a given copy of the Library. To do -this, you must alter all the notices that refer to this License, so -that they refer to the ordinary GNU General Public License, version 2, -instead of to this License. (If a newer version than version 2 of the -ordinary GNU General Public License has appeared, then you can specify -that version instead if you wish.) Do not make any other change in -these notices. - - Once this change is made in a given copy, it is irreversible for -that copy, so the ordinary GNU General Public License applies to all -subsequent copies and derivative works made from that copy. - - This option is useful when you wish to copy part of the code of -the Library into a program that is not a library. - - 4. You may copy and distribute the Library (or a portion or -derivative of it, under Section 2) in object code or executable form -under the terms of Sections 1 and 2 above provided that you accompany -it with the complete corresponding machine-readable source code, which -must be distributed under the terms of Sections 1 and 2 above on a -medium customarily used for software interchange. - - If distribution of object code is made by offering access to copy -from a designated place, then offering equivalent access to copy the -source code from the same place satisfies the requirement to -distribute the source code, even though third parties are not -compelled to copy the source along with the object code. - - 5. A program that contains no derivative of any portion of the -Library, but is designed to work with the Library by being compiled or -linked with it, is called a "work that uses the Library". Such a -work, in isolation, is not a derivative work of the Library, and -therefore falls outside the scope of this License. - - However, linking a "work that uses the Library" with the Library -creates an executable that is a derivative of the Library (because it -contains portions of the Library), rather than a "work that uses the -library". The executable is therefore covered by this License. -Section 6 states terms for distribution of such executables. - - When a "work that uses the Library" uses material from a header file -that is part of the Library, the object code for the work may be a -derivative work of the Library even though the source code is not. -Whether this is true is especially significant if the work can be -linked without the Library, or if the work is itself a library. The -threshold for this to be true is not precisely defined by law. - - If such an object file uses only numerical parameters, data -structure layouts and accessors, and small macros and small inline -functions (ten lines or less in length), then the use of the object -file is unrestricted, regardless of whether it is legally a derivative -work. (Executables containing this object code plus portions of the -Library will still fall under Section 6.) - - Otherwise, if the work is a derivative of the Library, you may -distribute the object code for the work under the terms of Section 6. -Any executables containing that work also fall under Section 6, -whether or not they are linked directly with the Library itself. - - 6. As an exception to the Sections above, you may also combine or -link a "work that uses the Library" with the Library to produce a -work containing portions of the Library, and distribute that work -under terms of your choice, provided that the terms permit -modification of the work for the customer's own use and reverse -engineering for debugging such modifications. - - You must give prominent notice with each copy of the work that the -Library is used in it and that the Library and its use are covered by -this License. You must supply a copy of this License. If the work -during execution displays copyright notices, you must include the -copyright notice for the Library among them, as well as a reference -directing the user to the copy of this License. Also, you must do one -of these things: - - a) Accompany the work with the complete corresponding - machine-readable source code for the Library including whatever - changes were used in the work (which must be distributed under - Sections 1 and 2 above); and, if the work is an executable linked - with the Library, with the complete machine-readable "work that - uses the Library", as object code and/or source code, so that the - user can modify the Library and then relink to produce a modified - executable containing the modified Library. (It is understood - that the user who changes the contents of definitions files in the - Library will not necessarily be able to recompile the application - to use the modified definitions.) - - b) Use a suitable shared library mechanism for linking with the - Library. A suitable mechanism is one that (1) uses at run time a - copy of the library already present on the user's computer system, - rather than copying library functions into the executable, and (2) - will operate properly with a modified version of the library, if - the user installs one, as long as the modified version is - interface-compatible with the version that the work was made with. - - c) Accompany the work with a written offer, valid for at - least three years, to give the same user the materials - specified in Subsection 6a, above, for a charge no more - than the cost of performing this distribution. - - d) If distribution of the work is made by offering access to copy - from a designated place, offer equivalent access to copy the above - specified materials from the same place. - - e) Verify that the user has already received a copy of these - materials or that you have already sent this user a copy. - - For an executable, the required form of the "work that uses the -Library" must include any data and utility programs needed for -reproducing the executable from it. However, as a special exception, -the materials to be distributed need not include anything that is -normally distributed (in either source or binary form) with the major -components (compiler, kernel, and so on) of the operating system on -which the executable runs, unless that component itself accompanies -the executable. - - It may happen that this requirement contradicts the license -restrictions of other proprietary libraries that do not normally -accompany the operating system. Such a contradiction means you cannot -use both them and the Library together in an executable that you -distribute. - - 7. You may place library facilities that are a work based on the -Library side-by-side in a single library together with other library -facilities not covered by this License, and distribute such a combined -library, provided that the separate distribution of the work based on -the Library and of the other library facilities is otherwise -permitted, and provided that you do these two things: - - a) Accompany the combined library with a copy of the same work - based on the Library, uncombined with any other library - facilities. This must be distributed under the terms of the - Sections above. - - b) Give prominent notice with the combined library of the fact - that part of it is a work based on the Library, and explaining - where to find the accompanying uncombined form of the same work. - - 8. You may not copy, modify, sublicense, link with, or distribute -the Library except as expressly provided under this License. Any -attempt otherwise to copy, modify, sublicense, link with, or -distribute the Library is void, and will automatically terminate your -rights under this License. However, parties who have received copies, -or rights, from you under this License will not have their licenses -terminated so long as such parties remain in full compliance. - - 9. You are not required to accept this License, since you have not -signed it. However, nothing else grants you permission to modify or -distribute the Library or its derivative works. These actions are -prohibited by law if you do not accept this License. Therefore, by -modifying or distributing the Library (or any work based on the -Library), you indicate your acceptance of this License to do so, and -all its terms and conditions for copying, distributing or modifying -the Library or works based on it. - - 10. Each time you redistribute the Library (or any work based on the -Library), the recipient automatically receives a license from the -original licensor to copy, distribute, link with or modify the Library -subject to these terms and conditions. You may not impose any further -restrictions on the recipients' exercise of the rights granted herein. -You are not responsible for enforcing compliance by third parties with -this License. - - 11. If, as a consequence of a court judgment or allegation of patent -infringement or for any other reason (not limited to patent issues), -conditions are imposed on you (whether by court order, agreement or -otherwise) that contradict the conditions of this License, they do not -excuse you from the conditions of this License. If you cannot -distribute so as to satisfy simultaneously your obligations under this -License and any other pertinent obligations, then as a consequence you -may not distribute the Library at all. For example, if a patent -license would not permit royalty-free redistribution of the Library by -all those who receive copies directly or indirectly through you, then -the only way you could satisfy both it and this License would be to -refrain entirely from distribution of the Library. - -If any portion of this section is held invalid or unenforceable under any -particular circumstance, the balance of the section is intended to apply, -and the section as a whole is intended to apply in other circumstances. - -It is not the purpose of this section to induce you to infringe any -patents or other property right claims or to contest validity of any -such claims; this section has the sole purpose of protecting the -integrity of the free software distribution system which is -implemented by public license practices.

If the distribution and/or use of the Library is restricted in -certain countries either by patents or by copyrighted interfaces, the -original copyright holder who places the Library under this License may add -an explicit geographical distribution limitation excluding those countries, -so that distribution is permitted only in or among countries not thus -excluded. In such case, this License incorporates the limitation as if -written in the body of this License. - - 13. The Free Software Foundation may publish revised and/or new -versions of the Lesser General Public License from time to time. -Such new versions will be similar in spirit to the present version, -but may differ in detail to address new problems or concerns. - -Each version is given a distinguishing version number. If the Library -specifies a version number of this License which applies to it and -"any later version", you have the option of following the terms and -conditions either of that version or of any later version published by -the Free Software Foundation. If the Library does not specify a -license version number, you may choose any version ever published by -the Free Software Foundation. - - 14. If you wish to incorporate parts of the Library into other free -programs whose distribution conditions are incompatible with these, -write to the author to ask for permission. For software which is -copyrighted by the Free Software Foundation, write to the Free -Software Foundation; we sometimes make exceptions for this. Our -decision will be guided by the two goals of preserving the free status -of all derivatives of our free software and of promoting the sharing -and reuse of software generally. - - NO WARRANTY - - 15. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO -WARRANTY FOR THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW. -EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR -OTHER PARTIES PROVIDE THE LIBRARY "AS IS" WITHOUT WARRANTY OF ANY -KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE -IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR -PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE -LIBRARY IS WITH YOU. SHOULD THE LIBRARY PROVE DEFECTIVE, YOU ASSUME -THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION. - - 16.

NAME

ecalength - prints audio file lenght and other information -

-

SYNOPSIS

- ecalength [-ahtsfmbcr] FILE1 [FILE2] [FILEn] -

-

DESCRIPTION

-

-This is ecalength, a few lines of code pompously named so because they -let one retrieve the length of an audio file from the command line -using ecasound's engine. -

-Limitations: -

-

- With files without header information (raw files), ecalength will only work - correctly if the audio file is at a sampling rate of 44100 hz. - (Addressed with the -a switch.) -

- It is not foolproof, feeding it with something other than an audio - file WILL result in ugly things being spewed back. - (A bit better) -

- A thousand more that I haven't thought of. -
-

-

OPTIONS

-

-

-

-h
-Prints this usage message. (help) -

-

-a[:]bits,channels,rate
-Changes the format assumed by default for headerless data. (adjust) -

-

-t
-Prints the summed length of all the files processed. (total) -(Ignored if with -s) -

-

-s
-Enables script mode: One info type per file per line. (script) -(Defaults to length in secs.) -

-

-f
-With -s will return the format string as info, alone it will -add it to the main display. (format) -

-

-b
-If -s and -f are enabled with this the info printed will be -the sample's bitwidth. (bits) -

-

-c
-If -s and -f are enabled with this the info printed will be -the channel count. (channel count) -

-

-r
-If -s and -f are enabled with this the info printed will be -the sampling rate. (rate) -

-

-m
-Will print human computable time as in main display but in -batch fashion. (minutes) (Only with -s) -

NAME

ecasound-iam - ecasound interactive mode -

SYNOPSIS

-

-

DESCRIPTION

-

-Ecasound library contains an interpreter module that understands -a set of commands aimed at controlling various library services. -This is called the ecasound interactive mode (EIAM). All programs -linked to ecasound library can use this facility. -

-

ECI API and return types

-A special case of interactive mode use is ecasound's control interface (ECI), -which is a small library providing easy access to the interactive -mode commands from outside of libecasound. When issuing inter commands using -the control interface, it's possible that commands also return information. -Currently supported return value types are: string [s], list of strings [S] -(elements separated by commas; escaped if necessary), integer [i], -long integer [li] and floating-point number [f]. These definitions are -used throughout this document. Commands that return nothing (void) are -marked with [-]. Additionally, return type [e] marks an error condition. -When an interactive mode command results in an error, an error string -explaining the condition is returned. -

-

Real-time commands

-It's not possible to use all interactive mode commands to modify and -control objects that belong to a connected chainsetup. Commands that -do NOT support this are: -

-

- cs-remove, cs-set-length, cs-set-length-samples, cs-toggle-loop, - cs-set-param, cs-option, - c-add, c-remove, c-rename, c-clear, - ai-add, ai-remove, ai-attach, ai-forward, ai-rewind, ai-set-position, - ai-set-position-samples, - ao-add, ao-add-default, ao-remove, ao-attach, ao-forward, ao-rewind, - ao-set-position, ao-set-position-samples. -
-

-If one of these commands is issued when a chainsetup is connected, -ecasound will first stop and disconnect the chainsetup, process -the command, and the reconnect. -

-In addition, most non-modifying (const) commands work with -connected setups. -

-

GENERAL

-
-

quit, q
-Quit ecasound session. What this means in practice depends on the -client implementation. In ecasound interactive mode, 'quit' terminates -the ecasound process. When sent over ecasound server connection (aka -NetECI), 'quit' terminates the active network connection, but does not -terminate the ecasound server process. [-] -

-

start, t
-Processing is started (play). Error string is return if any errors upon -startup are encountered. [e] -

-

stop, s
-Stop processing. [-] -

-

run
-Like 'start' but blocks until processing is finished. Error string -is return if any errors upon startup, or during process, are -encountered. [e] -

-

debug 'debug-level'
-Set debug level to 'debug-level'. Notice that client programs can -reimplement the debug routines. [-] -
-

-

resource-file 'path-to-file'
-Overrides the global and user resource files. Does not affect -already created objects. This command is equivalent to '-R' ecasound -option (see ecasound (1) man page). -

-

-prefix:arg1,...,argN
-Equivalent to issuing 'cs-option -prefix:arg1,...,argN). See documentation -for 'cs-option'. -

-

help', 'h'
-Help! [-] -

- -

-

GLOBAL

-

-

-

-

engine-status
-Returns a string describing the engine status (running, stopped, -finished, error, not ready). See also cs-status. [s] -

-

engine-launch
-Starts the real-time engine. Engine will execute the currently -connected chainsetup (see 'cs-connect). This action does not yet -start actual processing (see start and stop). When -ecasound is used as a JACK client, issuing engine-launch -makes ecasound an active JACK client (i.e. ecasound's ports -can be connected to other JACK clients). [-] -

-

engine-halt
-Stops the engine. Does not disconnect the chainsetup that -was running. See also cs-disconnet and stop. When -ecasound is used as a JACK client, engine-halt will -cause ecasound to become a deactivated client (all JACK -connections are torn down). [-] -

-

-

-

CHAINSETUPS

-Chainsetup is the central data object. All other objects (inputs, -outputs, chains, etc) are connected to some chainsetup. There can be -many chainsetups but only one can be connected. Similarly only -one chainsetup can be selected. If not otherwise specified operations -are done on the selected chainsetup. Some operations also require -that selected chainsetup is not connected. -

-

-

cs-add 'name'
-Adds a new chainsetup with name 'name'. 'name' is now -the selected chainsetup. [-] -

-

cs-remove
-Removes currently selected chainsetup. [-] -

-

cs-list
-Returns a list of all chainsetups. [S] -

-

cs-select 'name'
-Selects chainsetup 'name'. [-] -

-

cs-selected
-Returns the name of currently selected chainsetup. [s] -

-

cs-index-select 'cs_index', cs-iselect 'cs_index'
-Selects a chainsetup based on a short index string. Chainsetup names -can be rather long. This command can be used to avoid typing -these long names. 'cs_index' is an integer value, where '1' refers to -the first audio input/output. You can use 'cs-list' and 'cs-status' -to get a full list of currently available chainsetups. [-] -

-

cs-load 'filename'
-Adds a new chainsetup by loading it from file 'filename'. -'filename' is now the selected chainsetup. [-] -

-

cs-save
-Saves the currently selected chainsetup to file. If chainsetup was loaded -from a file, the saved version will replace the original. If it doesn't -have a default filename, it's saved to "chainsetup_name.ecs". [-] -

-

cs-save-as 'filename'
-Saves currently selected chainsetup to file 'filename'. [-] -

-

cs-edit
-Currently selected chainsetup is saved to a temporary file. This -file is loaded to an external editor (see ecasoundrc (5)). After -editing, the chainsetup is loaded back to ecasound. [-] -

-

cs-is-valid
-Whether currently selected chainsetup is valid (=can be connected)? [i] -

-

cs-connect
-Connect currently selected chainsetup to engine. When connecting, -all resources (e.g. files, soundcard devices, external programs) needed -to execute the chainsetup are reserved. Only one chainsetup can be connected -at a time. Error string is returned if connection fails (for instance -due to error in allocating the resources). [e] -

-

cs-disconnect
-Disconnect currently connected chainsetup. This action will free -all external resources needed by the chainsetup. [-] -

-

cs-connected
-Returns the name of currently connected chainsetup. [s] -

-

cs-rewind 'time-in-seconds', rewind 'time-in-seconds', rw 'time-in-seconds'
-Rewinds the current chainsetup position by 'time-in-seconds' seconds. -Position of all inputs and outputs attached to the selected chainsetup -is also affected. [-] -

-

cs-forward 'time-in-seconds', forward 'time-in-seconds', fw 'ttime-in-seconds'
-The current chainsetup position is forwarded by 'time-in-seconds' -seconds. Position of all inputs and outputs attached to the selected chainsetup -is also affected. [-] -

-

cs-set-position 'time-in-seconds', cs-setpos 'time-in-seconds', setpos 'time-in-seconds', set-position 'time-in-seconds'
-Sets the chainsetup position to 'time-in-seconds' seconds from the -beginning. Position of all inputs and outputs attached to the selected -chainsetup is also affected. [-] -

-

cs-set-position-samples 'time-in-samples'
-Sets the chainsetup position to 'time-in-samples' samples from the -beginning. Position of all inputs and outputs attached to the selected -chainsetup is also affected. [-] -

-

cs-get-position, cs-getpos, getpos, get-position
-Returns the current chainsetup position in seconds. [f] -

-

cs-get-position-samples
-Returns the current chainsetup position in samples. [li] -

-

cs-get-length, get-length
-Returns the chainsetup length in seconds (if known). [f] -

-

cs-get-length-samples, get-length-samples
-Returns the chainsetup length in samples (if known). [li] -

-

cs-set-length 'seconds'
-Sets processing time in seconds (doesn't have to be an integer value). -A special-case value of '-1' will set the chainsetup length -according to the longest input object. [-] -

-

cs-set-length-samples 'samples'
-Sets processing time in samples. [-] -

-

cs-toggle-loop
-Toggle looping. When processing is finished, engine will start -again from the initial position. It's not always possible to enable looping -(for instance all inputs and outputs have infinite length and -chainsetup length is not explicitly set with 'cs-set-length'). [-] -

-

cs-set-param
-Interpret general chainsetup parameters like for example -"-b" (buffersize), "-n" (name), etc. See ecasound (1) for -more info. [-] -

-

cs-set-audio-format 'bits,channels,sample_rate'
-Set the default sample parameters for currently selected chainsetup. -For example cd-quality audio would be "16,2,44100". This does the -same as command-line argument "-f" (see ecasound (1)). [-] -

-

cs-status, status, st
-Prints out status information about available chainsetup. -Detailed information is printed out for connected (=available -for running) nd selected (=available for editing) chainsetups. -Other chainsetups are listed, but further details are -suppressed. To get full details of a specific chainsetup, -select it with 'cs-select' or 'cs-iselect', and then -issue 'cs-select'. [s] -

-

cs-option '-prefix:arg1,...,argN'
-One powerful feature of the interactive-mode is that it -provides full access to ecasound's command-line syntax. -For instance, command "cs-option -efb:400,200" means that -a bandpass filter is added to the currently selected -chain, with initial parameters 400 (center frequency) -and 200 (width in Hz). -

-Note that session level options (such as setting debug level) -can not be used with 'cs-option' (i.e. only options that modify -chainsetups). -

-Note! Ecasound interactive mode implicitly interprets all strings -beginning with a '-' as "cs-option string". -

-

-

CHAINS

-Chain is a simple signal flow abstraction. Every chain has one input -and one output. All chain operators and their controllers are attached -to chains. Chains can be muted, unmuted and be bypassed. If not -otherwise stated, all operations are done to currently selected -chainsetup. -

-

-

-

c-status, cs
-Print status info about all chains. [s] -

It can be used for simple tasks like audio playback, -recording and format conversions, as well as for multitrack effect -processing, mixing, recording and signal recycling\&. Ecasound supports -a wide range of audio inputs, outputs and effect algorithms\&. -Effects and audio objects can be combined in various ways, and their -parameters can be controlled by operator objects like oscillators -and MIDI-CCs\&. A versatile console mode user-interface is included -in the package\&. -.PP -.SH "OPTIONS" - -.PP -Note! All options except those mentioned in \fIecasound options\fP and -\fIGlobal options\fP, can be used in ecasound chainsetup files (\&.ecs)\&. -.PP -\fBECASOUND OPTIONS\fP -.IP -These options are parsed and handled by the ecasound frontend binary and -are not passed to backend library\&. This means that these options may -not work in other applications that use ecasound libraries for their -functionality\&. -.IP -.IP "-c" -Starts ecasound in interactive mode\&. In interactive mode you can -control ecasound with simple commands ("start", "stop", "pause", -etc\&.)\&. See ecasound-iam \&. -.IP -.IP "-C" -Disables ecasound\&'s interactive mode (see \&'-c\&' and \&'-K\&')\&. - -.IP -.IP "-D" -Print all debug information to stderr (unbuffered, plain output -without ncurses)\&. -.IP -.IP "-s[:]chainsetup-file" -Create a new chainsetup from file \&'chainsetup-file\&' and add -it to the current session\&. Chainsetup files commonly have -a filename ending to the \&'\&.ecs\&' extension\&. A chainsetup can -contain inputs, outputs, chains, effects, controllers -- i\&.e\&. -objects one one specific configuration of audio processing -elements\&. A session, on the other hand, is a collection of -one or more chainsetups\&. Only one of the chainsetups may be -connected (i\&.e\&. it can be run/processed)\&. But it is possible -to have another chainsetup select (i\&.e\&. can be configured) -while other one is current connteced (i\&.e\&. running)\&. -.IP -.IP "-E "cmd1 [[args] ; cmd2 args ; \&.\&.\&. ; cmdN]"" -Execute a set of Ecasound Interactive mode (EIAM) commands -at launch\&. These commands are executed immediately after -ecasound is started\&. If the command line contains sufficient -options to create a valid chainsetup that will be executed, -the launch commands are executed after the other command -line options are parsed, but before the processing engine -is started\&. Note that this command is a feature of -the ecasound frontend binary and not supported by -the library backend\&. This means that other clients may -not support the \&'-E\&' option, and also that the launch -commands are not saved as part of chainsetup or session -state\&. -.IP -.IP "--server" -Enables the so called NetECI mode, in which ecasound can -be controlled remotely over a socket connection\&. When -activated, clients can connect to the running ecasound -session, and use interactive mode commands to control and -observe ecasound processing\&. -.IP -The NetECI protocol is defined in -Ecasound\&'s Programmer Guide -.IP -One example client using this feature is ecamonitor(1)\&. This -utility is included in the Ecasound distribution package (requires -a working Python environment)\&. -.IP -\fIWarning!\fP If the machine running ecasound, is connected to -a public network, be sure to block ecasound\&'s port in your -firewall! As there is no access control implemented for incoming -connections, anyone can otherwise connect, control and observe your -ecasound sessions\&. -This option replaces \&'--daemon\&' (deprecated in 2\&.6\&.0)\&. -.IP -.IP "--server-tcp-port=NNN" -Set the TCP port used by the daemon mode\&.

Specifying this option -will disable the normal policy of querying both global and user (if exists) -resource files\&. -.IP -.IP "-q" -Quiet mode, no output\&. Same as \fI-d:0\fP\&. -.IP -\fBGENERAL CHAINSETUP OPTIONS\fP - -.IP -.IP "-a:chainname1, chainname2, \&.\&.\&." -Selects active signal chains\&. All inputs and outputs following -this \&'-a\&' option are assigned to selected chains (until a new -a -option is specified)\&. When adding effects, controllers and other -chain operators, only one chain can be selected at a time\&. If no -a option -has been given, chain \&'default\&' is used instead when adding objects\&. -Chain name \&'all\&' is also reserved\&. It will cause all existing chains -to be selected\&. By giving multiple -a options, you can control to which -chains effects, inputs and outputs are assigned to\&. Look at the \fBEXAMPLES\fP -section for more detailed info about the usage of this option\&. -.IP -.IP "-n:name" -Sets the name of chainsetup to \&'name\&'\&. If not specified, defaults -either to "command-line-setup" or to the file name from which -chainsetup was loaded\&. Whitespaces are not allowed\&. -.IP -.IP "-x" -Truncate outputs\&. All output object are opened in overwrite mode\&. -Any existing files will be truncated\&. -.IP -.IP "-X" -Open outputs for updating\&. Ecasound opens all outputs - if target -format allows it - in readwrite mode\&. -.IP -.IP "-z:feature" -Enables \&'feature\&'\&. Most features can be disabled using notation -\fI-z:nofeature\fP\&. \&'-z:db,dbsize\&' enables double-buffering for audio -objects that support it (dbsize=0 for default, otherwise buffer -size in sample frames)\&. \&'-z:nodb\&' disables double-buffering\&. -\&'-z:intbuf\&' and \&'-z:nointbuf\&' control whether extra internal buffering -is allowed for realtime devices\&. Disabling this can reduce -latency times in some situations\&. With \&'-z:xruns\&', processing will be -halted if an under/overrun occurs\&. \&'-z:multitrack\&' and -\&'z:nomultitrack\&' can be used to force ecasound to enable or disable -multitrack-mode\&. In rare cases you may want to explicitly specify -the recording offset with \&'-z:multitrack,offset-in-samples\&'\&. The -offset is the amount of samples skipped when recording from -real-time inputs\&. \&'-z:psr\&' enables the \fIprecise-sample-rates\fP mode -for OSS-devices\&. \&'-z:mixmode,sum\&' enables mixing mode where channels -are mixed by summing all channels\&. The default is \&'-z:mixmode,avg\&', -in which channels are mixed by averaging\&. Mixmode selection was first -added to ecasound 2\&.4\&.0\&. -See ecasoundrc man page\&. -.IP -\fBCHAINSETUP BUFFERING AND PERFORMANCE OPTIONS\fP - -.IP -.IP "-B:buffering_mode" -Selects the default buffering mode\&. Mode is one of: \&'auto\&' (default), -\&'nonrt\&', \&'rt\&', \&'rtlowlatency\&'\&. -.IP -.IP "-b:buffer size" -Sets the size of buffer in samples (must be an exponent of 2)\&. This -is quite an important option\&. For real-time processing, you should -set this as low as possible to reduce the processing delay\&. Some -machines can handle buffer values as low as 64 and 128\&. In some -circumstances (for instance when using oscillator envelopes) small -buffer sizes will make envelopes act more smoothly\&. When not processing -in real-time (all inputs and outputs are normal files), values between -512 - 4096 often give better results\&. Default is 1024\&. -.IP -.IP "-r:sched_priority" -Use realtime scheduling policy (SCHED_FIFO)\&. This is impossible if -ecasound doesn\&'t have root priviledges\&. Beware! This gives better -performance, but can cause total lock-ups if something goes wrong\&. -The \&'sched_priority\&' can be omitted (0=omitted)\&. If given, -this is the static priority to the highest priority ecasound thread\&. -Other ecasound threads run with priority \&'sched_priority-1\&.\&.\&.n\&'\&. -Value \&'-1\&' can be used to disable raised-priority mode\&. -.IP -.IP "-z:feature" -Relevant features are -z:db,xxx (-z:nodb) and -z:intbuf (-z:nointbuf)\&. -See section \fIGeneral chainsetup options\fP for details\&. -.IP -\fBPROCESSING CONTROL\fP -.IP "-t:seconds" -Sets processing time in seconds (doesn\&'t have to be an integer value)\&. -If processing time isn\&'t set, engine stops when all inputs are -finished\&. This option is equivalent to the \&'cs-set-length\&' EIAM -command\&. A special-case value of \&'-1\&' will set the chainsetup length -according to the longest input object\&. -.IP -.IP "-tl" -Enables looping\&. When processing is finished, engine will start -again from beginning\&. This option is equivalent to the \&'cs-loop\&' -EIAM command\&. -.IP -\fBINPUT/OUTPUT SETUP\fP -.PP -See ecasound user\&'s guide for -more detailed documentation\&. -.PP -.IP "-G:mgrtype,optstring" -Sets options for audio object manager type \&'mgrtype\&'\&. -For available options, see "OBJECT TYPE SPECIFIC NOTES" below\&. -.IP -.IP "-f:sample_format,channel,sample-rate,interleaving" -Sets the audio stream parameters for subsequent audio objects\&. -To set different parameters for different audio objects, multiple -\&'-f\&' options have to be specified (note the ordering, the \&'-f\&' -options should precede the audio objects for them to have any -effect)\&. See documentation for \&'-i\&' and \&'-o\&' options\&. -.IP -When an audio object is opened (e\&.g\&. a file or sound device -is opened, or connection is made to a sound server), the audio -stream parameters are passed to the object\&. It should be noted that -not all audio objects allow to set any or all of the parameters\&. -For instance when opening existing audio files, many file formats -have a header describing the file audio parameters\&. In -these cases the audio file header overrides the parameters -passed with \&'-f\&' option\&. Similarly when creating JACK inputs and -outputs, the JACK server mandates the sampling rate and sample -format\&. -.IP -If no \&'-f\&' option is specified, or some of the argument fields -are left empty (e\&.g\&. \&'-f:,2,44100\&'), ecasound will use default values\&. These -default values are defined in ecasoundrc configuration file\&. See -ecasoundrc(5) manual page\&. -.IP -Note that ecasound opens out files by default in update mode\&. -Unless option \&'-x\&' (overwrite outputs) option is given, -audio parameters of an existing audio file take preference over -the params set with \&'-f\&'\&. -.IP -Sample format is given as a formatted string\&. The first letter is -either "u", "s" and "f" (unsigned, signed, floating point)\&. The -following number specifies sample size in bits\&. If sample is -little endian, "_le" is added to the end\&. Similarly if big endian, -"_be" is added\&. If endianess is not specified, host byte-order is used\&. -Currently supported formats are "u8" (same as "8"), "s16_le" (same -as "16"), "s16_be", "s24_le", "s24_be", "s32_le", "s32_be", "f32_le" -and "f32_be"\&. An empty string "" picks the system default sample -format\&. -.IP -The 4th parameter defines the channel layout\&. The available -options are \&'i\&' (interleaved\&' and \&'n\&' (noninterleaved)\&. With -the noninterleaved setting, ecasound will process samples -one channel at a time, and the blocksize is set with \&'-b\&'\&. -The default setting is \&'i\&'\&. -.IP -.IP "-y:seconds" -Sets starting position for last specified input/output\&. If -you need more flexible control over audio objects, you should -use the \fI\&.ewf\fP format\&. -.IP -.IP "-i[:]input-file-or-device[,params]" -Specifies a new input source that is connected to all selected chains (chains -are selected with \&'-a:\&.\&.\&.\&')\&. Connecting multiple inputs to the same chain is -not possible, but one input can be connected to multiple chains\&. Input can be -a a file, device or some other audio object (see below)\&. If the input is -a file, its type is determined using the file name extension\&. If the object -name contains any commas, the name must be enclosed in backquotes to avoid -confusing the parser\&. Currently supported formats are RIFF WAVE files (\&.wav), -audio-cd tracks (\&.cdr), ecasound EWF files (\&.ewf), RAW audio data (\&.raw) and -MPEG audio files (\&.mp2,\&.mp3)\&. More audio formats are supported via libaudiofile -and libsndfile libraries (see documentation below)\&. MikMod is also supported (\&.xm, -\&.mod, \&.s3m, \&.it, etc)\&. MIDI files (\&.mid) are supported using Timidity++\&. -Similarly Ogg Vorbis (\&.ogg) can be read, and written if ogg123 and vorbize tools -are installed; FLAC files (\&.flac) with flac command-line tools or using -libsndfile; and AAC files (\&.aac/\&.m4a/\&.mp4) with faad2/faac tools\&. Supported -realtime devices are OSS audio devices (/dev/dsp*), ALSA audio and loopback -devices and JACK audio subsystem\&. If no inputs are specified, the first -non-option (doesn\&'t start with \&'-\&') command line argument is considered -to be an input\&. -.IP -.IP "-o[:]output-file-or-device[,params]" -Works in the same way as the -i option\&. If no outputs are specified, -the default output device is used (see ~/\&.ecasoundrc)\&.

To create a JACK input or output object, one should use \fB-i jack\fP and -\fB-o jack\fP\&. These create JACK client ports "ecasound:in_N" and -"ecasound:out_n" respectively (\&'N\&' is replaced by the channel number)\&. -Ecasound automatically creates one JACK port for each channel (number -of channels is set with \fB-f:bits,channels,rate\fP option)\&. -.IP -It is important to note that by default JACK ports are not connected -anywhere (e\&.g\&. to soundcard input/outputs, or to other apps)\&.

Child sampling rate can be -replaced with keyword \&'auto\&'\&. In this case ecasound will try -to query the child object for its sampling rate\&. This works with -files formats such as \&.wav which store meta information about -the audio file format\&. To use \&'auto\&' in the previous example, -\fBecasound -f:16,2,44100 -i resample,auto,foo\&.wav -o /dev/dsp\fP\&. -.IP -Parameters 4\&.\&.\&.N are passed as is to the child object (i\&.e\&. -"-i resample,22050,foo\&.wav,bar1,bar2" will pass parameters -"bar1,bar2" to the "foo\&.wav" object\&. -.IP -If ecasound was compiled with support for libsamplerate, you can -use \&'resample-hq\&' to use the highest quality resampling algorithm -available\&.

NAME

ecasound - sample editor, multitrack recorder, fx-processor, etc. -

-

SYNOPSIS

- ecasound [ general_options ] { [ chain_setup ] [ effect_setup ] [ input_setup ] [ output_setup ] } -

-

DESCRIPTION

-

-Ecasound is a software package designed for multitrack audio -processing. It can be used for simple tasks like audio playback, -recording and format conversions, as well as for multitrack effect -processing, mixing, recording and signal recycling. Ecasound supports -a wide range of audio inputs, outputs and effect algorithms. -Effects and audio objects can be combined in various ways, and their -parameters can be controlled by operator objects like oscillators -and MIDI-CCs. A versatile console mode user-interface is included -in the package. -

-

OPTIONS

-

-Note! All options except those mentioned in ecasound options and - Global options, can be used in ecasound chainsetup files (.ecs). -

-

-

- -ECASOUND OPTIONS -

-These options are parsed and handled by the ecasound frontend binary and -are not passed to backend library. This means that these options may -not work in other applications that use ecasound libraries for their -functionality. -

-

-

-c
-Starts ecasound in interactive mode. In interactive mode you can -control ecasound with simple commands ("start", "stop", "pause", -etc.). See ecasound-iam . -

-

-C
-Disables ecasound's interactive mode (see '-c' and '-K'). -
-

-

-D
-Print all debug information to stderr (unbuffered, plain output -without ncurses). -

-

-s[:]chainsetup-file
-Create a new chainsetup from file 'chainsetup-file' and add -it to the current session. Chainsetup files commonly have -a filename ending to the '.ecs' extension. A chainsetup can -contain inputs, outputs, chains, effects, controllers -- i.e. -objects one one specific configuration of audio processing -elements. A session, on the other hand, is a collection of -one or more chainsetups. Only one of the chainsetups may be -connected (i.e. it can be run/processed). But it is possible -to have another chainsetup select (i.e. can be configured) -while other one is current connteced (i.e. running). -

-

-E "cmd1 [[args] ; cmd2 args ; ... ; cmdN]"
-Execute a set of Ecasound Interactive mode (EIAM) commands -at launch. These commands are executed immediately after -ecasound is started. If the command line contains sufficient -options to create a valid chainsetup that will be executed, -the launch commands are executed after the other command -line options are parsed, but before the processing engine -is started. Note that this command is a feature of -the ecasound frontend binary and not supported by -the library backend. This means that other clients may -not support the '-E' option, and also that the launch -commands are not saved as part of chainsetup or session -state. -

-

--server
-Enables the so called NetECI mode, in which ecasound can -be controlled remotely over a socket connection. When -activated, clients can connect to the running ecasound -session, and use interactive mode commands to control and -observe ecasound processing. -

-The NetECI protocol is defined in -Ecasound's Programmer Guide -

-One example client using this feature is ecamonitor(1). This -utility is included in the Ecasound distribution package (requires -a working Python environment). -

-Warning! If the machine running ecasound, is connected to -a public network, be sure to block ecasound's port in your -firewall! As there is no access control implemented for incoming -connections, anyone can otherwise connect, control and observe your -ecasound sessions. -This option replaces '--daemon' (deprecated in 2.6.0). -

-

--server-tcp-port=NNN
-Set the TCP port used by the daemon mode. By default -ecasound will use port number 2868. -This option replaces '--daemon-port' (deprecated in 2.6.0). -

-

--no-server
-Disable ecasound's daemon mode. This is the default. -This option replaces '--nodaemon' (deprecated in 2.6.0). -

-

--osc-udp-port=NNN
-Enables support for Open Source Control (OSC). Ecasound will listen -for incoming OSC messages on UDP port NNN. Ecasound's OSC interface -is documented at: -<http://ecasound.git.sourceforge.net/git/gitweb.cgi?p=ecasound/ecasound;a=blob;f=Documentation/ecasound_osc_interface.txt;hb=HEAD> -

-Note that OSC support is still experimental and the interface -might change in later versions of Ecasound. -

-This option was added to ecasound 2.7.0. -

-

--keep-running,-K
-Do not exit when processing is finished/stopped. Only affects -non-interactive operating mode (see -c/-C). -Option added to ecasound 2.4.2. -

-

--help,-h
-Show this help. -

-

--version
-Print version info. -

-

-

- -GLOBAL OPTIONS -

-

-

-

-d, -dd, -ddd
-Increase the amount of printed debug messages. -d adds -some verbosity, while -ddd results in very detailed -output. -

-

-d:debug_level
-Set the debug level mask to 'debug_level'. This a bitmasked value with -the following classes: errors (1), info (2), subsystems (4), module_names (8), -user_objects (16), system_objects 32, functions (64), continuous (128) and -eiam_return_values (256). Default is 271 (1+2+4+8+256). See sourcode -documentation for the ECA_LOGGER class for more detailed information. -

-

-R[:]path-to-file
-Use ecasound resource file (see ecasoundrc man page) 'path-to-file' as -the only source of setting resource value. Specifying this option -will disable the normal policy of querying both global and user (if exists) -resource files. -

-

-q
-Quiet mode, no output. Same as -d:0. -

-

-

- -GENERAL CHAINSETUP OPTIONS -

-

-

-a:chainname1, chainname2, ...
-Selects active signal chains. All inputs and outputs following -this '-a' option are assigned to selected chains (until a new -a -option is specified). When adding effects, controllers and other -chain operators, only one chain can be selected at a time. If no -a option -has been given, chain 'default' is used instead when adding objects. -Chain name 'all' is also reserved. It will cause all existing chains -to be selected. By giving multiple -a options, you can control to which -chains effects, inputs and outputs are assigned to. Look at the EXAMPLES -section for more detailed info about the usage of this option. -

-

-n:name
-Sets the name of chainsetup to 'name'. If not specified, defaults -either to "command-line-setup" or to the file name from which -chainsetup was loaded. Whitespaces are not allowed. -

-

-x
-Truncate outputs. All output object are opened in overwrite mode. -Any existing files will be truncated. -

-

-X
-Open outputs for updating. Ecasound opens all outputs - if target -format allows it - in readwrite mode. -

-

-z:feature
-Enables 'feature'. Most features can be disabled using notation --z:nofeature. '-z:db,dbsize' enables double-buffering for audio -objects that support it (dbsize=0 for default, otherwise buffer -size in sample frames). '-z:nodb' disables double-buffering. -'-z:intbuf' and '-z:nointbuf' control whether extra internal buffering -is allowed for realtime devices. Disabling this can reduce -latency times in some situations. With '-z:xruns', processing will be -halted if an under/overrun occurs. '-z:multitrack' and -'z:nomultitrack' can be used to force ecasound to enable or disable -multitrack-mode. In rare cases you may want to explicitly specify -the recording offset with '-z:multitrack,offset-in-samples'. The -offset is the amount of samples skipped when recording from -real-time inputs. '-z:psr' enables the precise-sample-rates mode -for OSS-devices. '-z:mixmode,sum' enables mixing mode where channels -are mixed by summing all channels. The default is '-z:mixmode,avg', -in which channels are mixed by averaging. Mixmode selection was first -added to ecasound 2.4.0. -See ecasoundrc man page. -

-

-

- -CHAINSETUP BUFFERING AND PERFORMANCE OPTIONS -

-

-

-B:buffering_mode
-Selects the default buffering mode. Mode is one of: 'auto' (default), -'nonrt', 'rt', 'rtlowlatency'. -

-

-b:buffer size
-Sets the size of buffer in samples (must be an exponent of 2). This -is quite an important option. For real-time processing, you should -set this as low as possible to reduce the processing delay. Some -machines can handle buffer values as low as 64 and 128. In some -circumstances (for instance when using oscillator envelopes) small -buffer sizes will make envelopes act more smoothly. When not processing -in real-time (all inputs and outputs are normal files), values between -512 - 4096 often give better results. Default is 1024. -

-

-r:sched_priority
-Use realtime scheduling policy (SCHED_FIFO). This is impossible if -ecasound doesn't have root priviledges. Beware! This gives better -performance, but can cause total lock-ups if something goes wrong. -The 'sched_priority' can be omitted (0=omitted). If given, -this is the static priority to the highest priority ecasound thread. -Other ecasound threads run with priority 'sched_priority-1...n'. -Value '-1' can be used to disable raised-priority mode. -

-

-z:feature
-Relevant features are -z:db,xxx (-z:nodb) and -z:intbuf (-z:nointbuf). -See section General chainsetup options for details. -

-

-

- -PROCESSING CONTROL -

-

-t:seconds
-Sets processing time in seconds (doesn't have to be an integer value). -If processing time isn't set, engine stops when all inputs are -finished. This option is equivalent to the 'cs-set-length' EIAM -command. A special-case value of '-1' will set the chainsetup length -according to the longest input object. -

-

-tl
-Enables looping. When processing is finished, engine will start -again from beginning. This option is equivalent to the 'cs-loop' -EIAM command. -

-

-

- -INPUT/OUTPUT SETUP -

-See ecasound user's guide for -more detailed documentation. -

-

-

-G:mgrtype,optstring
-Sets options for audio object manager type 'mgrtype'. -For available options, see "OBJECT TYPE SPECIFIC NOTES" below. -

-

-f:sample_format,channel,sample-rate,interleaving
-Sets the audio stream parameters for subsequent audio objects. -To set different parameters for different audio objects, multiple -'-f' options have to be specified (note the ordering, the '-f' -options should precede the audio objects for them to have any -effect). See documentation for '-i' and '-o' options. -

-When an audio object is opened (e.g. a file or sound device -is opened, or connection is made to a sound server), the audio -stream parameters are passed to the object. It should be noted that -not all audio objects allow to set any or all of the parameters. -For instance when opening existing audio files, many file formats -have a header describing the file audio parameters. In -these cases the audio file header overrides the parameters -passed with '-f' option. Similarly when creating JACK inputs and -outputs, the JACK server mandates the sampling rate and sample -format. -

-If no '-f' option is specified, or some of the argument fields -are left empty (e.g. '-f:,2,44100'), ecasound will use default values. These -default values are defined in ecasoundrc configuration file. See -ecasoundrc(5) manual page. -

-Note that ecasound opens out files by default in update mode. -Unless option '-x' (overwrite outputs) option is given, -audio parameters of an existing audio file take preference over -the params set with '-f'. -

-Sample format is given as a formatted string. The first letter is -either "u", "s" and "f" (unsigned, signed, floating point). The -following number specifies sample size in bits. If sample is -little endian, "_le" is added to the end. Similarly if big endian, -"_be" is added. If endianess is not specified, host byte-order is used. -Currently supported formats are "u8" (same as "8"), "s16_le" (same -as "16"), "s16_be", "s24_le", "s24_be", "s32_le", "s32_be", "f32_le" -and "f32_be". An empty string "" picks the system default sample -format. -

-The 4th parameter defines the channel layout. The available -options are 'i' (interleaved' and 'n' (noninterleaved). With -the noninterleaved setting, ecasound will process samples -one channel at a time, and the blocksize is set with '-b'. -The default setting is 'i'. -

-

-y:seconds
-Sets starting position for last specified input/output. If -you need more flexible control over audio objects, you should -use the .ewf format. -

-

-i[:]input-file-or-device[,params]
-Specifies a new input source that is connected to all selected chains (chains -are selected with '-a:...'). Connecting multiple inputs to the same chain is -not possible, but one input can be connected to multiple chains. Input can be -a a file, device or some other audio object (see below). If the input is -a file, its type is determined using the file name extension. If the object -name contains any commas, the name must be enclosed in backquotes to avoid -confusing the parser. Currently supported formats are RIFF WAVE files (.wav), -audio-cd tracks (.cdr), ecasound EWF files (.ewf), RAW audio data (.raw) and -MPEG audio files (.mp2,.mp3). More audio formats are supported via libaudiofile -and libsndfile libraries (see documentation below). MikMod is also supported (.xm, -.mod, .s3m, .it, etc). MIDI files (.mid) are supported using Timidity++. -Similarly Ogg Vorbis (.ogg) can be read, and written if ogg123 and vorbize tools -are installed; FLAC files (.flac) with flac command-line tools or using -libsndfile; and AAC files (.aac/.m4a/.mp4) with faad2/faac tools. Supported -realtime devices are OSS audio devices (/dev/dsp*), ALSA audio and loopback -devices and JACK audio subsystem. If no inputs are specified, the first -non-option (doesn't start with '-') command line argument is considered -to be an input. -

-

-o[:]output-file-or-device[,params]
-Works in the same way as the -i option. If no outputs are specified, -the default output device is used (see ~/.ecasoundrc). If the object -name contains any commas, the name must be enclosed in backquotes to -avoid confusing the parser. Note, many object types do not support -output (e.g. MikMod, MIDI and many others). -

-OBJECT TYPE SPECIFIC NOTES -

ALSA devices - 'alsa'
-When using ALSA drivers, instead of a device filename, you need to -use the following option syntax: -i[:]alsa,pcm_device_name. -

-

ALSA direct-hw and plugin access - 'alsahw', 'alsaplugin'
-It's also possible to use a specific card and device combination -using the following notation: -i[:]alsahw,card_number,device_number,subdevice_number. -Another option is the ALSA PCM plugin layer. It works just like -the normal ALSA pcm-devices, but with automatic channel count and -sample format conversions. Option syntax is --i[:]alsaplugin,card_number,device_number,subdevice_number. -

-

aRts input/output - 'arts'
-If enabled at compile-time, ecasound supports audio input and -output using aRts audio server. Option syntax is -i:arts, --o:arts. -

-

Audio file sequencing - 'audioloop', 'select', 'playat'
-Ecasound provides a set of special audio object types that -can be used for temporal sequencing of audio files - i.e. looping, -playing only a select portion of a file, playing file at a spefific -time, and other such operation. -

-Looping is possible with -i:audioloop,file.ext,params. The -file name (or any object type understood by Ecasound) given -as the second parameter is played back continuously looping -back to the beginning when the end of file is reached. Any additional -parameters given are passed unaltered to the file object. -Parameters 3...N are passed as is to the child object (i.e. -"-i audioloop,foo.wav,bar1,bar2" will pass parameters -"bar1,bar2" to the "foo.wav" object. -

-To select and use only a specific segment of an audio object, -the -i:select,start-time,duration,file.ext,params can -be used. This will play "duration" of "file.ext", starting at -"start-time". The time values should be given as seconds (e.g. -"2.25", or as samples (e.g. "25000sa"). Parameters 4...N are -passed as is to the child object. -

-To play an audio object at a given moment in time, -the -i:playat,play-at-time,file.ext,params can be -used. This will play "file.ext" after position reaches -"play-at-time". The time values should be given as seconds (e.g. -"2.25", or as samples (e.g. "25000sa"). Parameters 2...N are -passed as is to the child object. -

-

Ecasound Wave Files (EWF) - '*.ewf'
-A special file format that allows to slice and loop full (or segments) -of audio files. This format is specific to Ecasound. -See ecasound user's guide for more -detailed information. -

-See also audio object types 'audioloop', 'select' and 'playat'. -

-

JACK input/outputs - Overview
-JACK is a low-latency audio server that can be used to connect -multiple independent audio application to each other. -It is different from other audio server efforts in that -it has been designed from the ground up to be suitable for low-latency -professional audio work. -

-

JACK input/outputs - 'jack'
-Ecasound provides multiple ways to communicate with JACK -servers. To create a JACK input or output object, one should use -i jack and --o jack. These create JACK client ports "ecasound:in_N" and -"ecasound:out_n" respectively ('N' is replaced by the channel number). -Ecasound automatically creates one JACK port for each channel (number -of channels is set with -f:bits,channels,rate option). -

-It is important to note that by default JACK ports are not connected -anywhere (e.g. to soundcard input/outputs, or to other apps). One thus -has to connect the ports with an external program (e.g. "QJackCtl" -or "jack_connect"). -

-

JACK input/outputs - 'jack,clientname,portprefix'
-"jack,clientname" For simple use scanerios, ecasound provides a way to autoconnect -the ecasound ports. This can be done with by giving the peer client -name as the second parameter to the "jack" object, e.g. -o jack,clientname. -As an example, -o jack,system will create an output that is -automatically connected to outputs of the default system soundcard. -The client parameter can be omitted, in which case no automatic -connections are made. -

-If one needs to change the port prefix (e.g. "in" in client name -"ecasound:in_N"), the prefix can be specified as the third parameter to -"jack" object, e.g. -o jack,,fxout. Also the third parameter can be -omitted, in which case the default prefixes "in" and "out" are used. -

-

JACK input/outputs - 'jack_multi'
-A variant of 'jack' object type is 'jack_multi'. The full object syntax -is jack_multi,destport1,...,destportN. When a 'jack_multi' object -is connected to a JACK server, first channel of the object is connected -to JACK port 'destport1', second to 'destport2' and so forth. For -instance "-f:32,2,44100 -o jack_multi,foo:in,bar:in" -creates a stereo ecasound output object, with its left and right -channels routed to two difference JACK clients. The destination ports -must be active when the ecasound engine is launched, or otherwise -the connections cannot be established. If destination ports are not -specified for all channels, or zero length strings are given, those -ports are not connected at launch by ecasound. -

-

JACK input/outputs - 'jack_alsa', 'jack_auto', 'jack_generic' (**deprecated since 2.6.0**)
-Ecasound 2.5 and older supported "jack_alsa", "jack_auto" and "jack_generic" object -types, but these are now replaced by a more generic "jack" interface, and thus are -now deprecated (they work but are no longer documented). -

-

JACK input/outputs - client options
-Additionally global JACK options can be set using --G:jack,client_name,operation_mode option. 'client_name' -is the name used when registering ecasound to the JACK system. -If 'operation_mode' is "notransport", ecasound will ignore -any transport state changes in the JACK-system; in mode -"send" it will send all start, stop and position-change events to -other JACK clients; in mode "recv" ecasound will follow JACK start, -stop and position-change events; and mode "sendrecv" (the default) -which is a combination of the two previous modes. -

-More details about ecasound's JACK support can be found -from Ecasound User's Guide. -

-

Libaudiofile - 'audiofile'
-If libaudiofile support was enabled at compile-time, this -option allows you to force Ecasound to use libaudiofile -for reading/writing a certain audio file. Option syntax -is -i:audiofile,foobar.ext (same for -o). -

-

Libsndfile - 'sndfile'
-If libsndfile support was enabled at compile-time, this -option allows you to force Ecasound to use libsndfile -for reading/writing a certain audio file. Option syntax -is -i:sndfile,foobar.ext[,.format-ext] (same for -o). -The optional third parameter "format" can be used to -override the audio format (for example you can create an -AIFF file with filename "foo.wav"). -

-

Loop device - 'loop'
-Loop devices make it possible to route (loop back) data between -chains. Option syntax is -[io][:]loop,tag. If you add -a loop output with tag '1', all data written to this output is routed -to any loop input with tag '1'. The tag can be either numerical -(e.g. '-i:loop,1') or a string (e.g. "-i:loop,vocals"). Like -with other input/output objects, you can attach the same loop -device to multiple chains and this way split/mix the signal. -

-Note: this 'loop' device is different from 'audioloop' (latter -added to ecasound v2.5.0). -

-

Mikmod - 'mikmod'
-If mikmod support was enabled at compile-time, this -option allows you to force Ecasound to use Mikmod -for reading/writing a certain module file. Option syntax -is -i:mikmod,foobar.ext. -

-

Null inputs/outputs - 'null'
-If you specify "null" or "/dev/null" as the input or output, -a null audio device is created. This is useful if you just want -to analyze sample data without writing it to a file. There's -also a realtime variant, "rtnull", which behaves just like "null" -objects, except all i/o is done at realtime speed. -

-

Resample - 'resample'
-Object type 'resample' can be used to resample audio -object's audio data to match the sampling rate used -in the active chainsetup. For example, -ecasound -f:16,2,44100 -i resample,22050,foo.wav -o /dev/dsp, -will resample file from 22.05kHz to 44.1kHz and write the -result to the soundcard device. Child sampling rate can be -replaced with keyword 'auto'. In this case ecasound will try -to query the child object for its sampling rate. This works with -files formats such as .wav which store meta information about -the audio file format. To use 'auto' in the previous example, -ecasound -f:16,2,44100 -i resample,auto,foo.wav -o /dev/dsp. -

-Parameters 4...N are passed as is to the child object (i.e. -"-i resample,22050,foo.wav,bar1,bar2" will pass parameters -"bar1,bar2" to the "foo.wav" object. -

-If ecasound was compiled with support for libsamplerate, you can -use 'resample-hq' to use the highest quality resampling algorithm -available. To force ecasound to use the internal resampler, -'resampler-lq' (low-quality) can be used. -

-

Reverse - 'reverse'
-Object type 'reverse' can be used to reverse audio -data coming from an audio object. As an example, -ecasound -i reverse,foo.wav -o /dev/dsp will play -'foo.wav' backwards. Reversing output objects is not -supported. Note! Trying to reverse audio object types with really -slow seek operation (like mp3), works extremely badly. -Try converting to an uncompressed format (wav or raw) -first, and then do reversation. -

-Parameters 3...N are passed as is to the child object (i.e. -"-i reverse,foo.wav,bar1,bar2" will pass parameters -"bar1,bar2" to the "foo.wav" object. -

-

System standard streams and named pipes - 'stdin', 'stdout'
-You can use standard streams (stdin and stdout) by giving stdin -or stdout as the file name. Audio data is assumed to be in -raw/headerless (.raw) format. If you want to use named pipes, -create them with the proper file name extension before use. -

-

Tone generator - 'tone'
-To generate a test tone, input -i:tone,type,freq,duration-secs -can be used. Parameter 'type' specifies the tone type: currently -only 'sine' is supported. The 'freq' parameter sets the frequency -of the generated tone and 'duration-secs' the length of the generated -stream. Specifying zero, or a negative value, as the duration will -produce an infinite stream. This feature was first added to Ecasound -2.4.7. -

-

Typeselect - 'typeselect'
-The special 'typeselect' object type can be used to override -how ecasound maps filename extensions and object types. For -instance ecasound -i typeselect,.mp3,an_mp3_file.wav -o /dev/dsp. -would play the file 'an_mp3_file.wav' as an mp3-file and not -as an wav-file as would happen without typeselect. -

-Parameters 4...N are passed as is to the child object (i.e. -"-i typeselect,.au,foo.wav,bar1,bar2" will pass parameters -"bar1,bar2" to the "foo.wav" object. -

-

-

- -MIDI SETUP -

-

-

MIDI I/O devices - general
-If no MIDI-device is specified, the default MIDI-device is -used (see ecasoundrc(5)). -

-

-Md:rawmidi,device_name
-Add a rawmidi MIDI I/O device to the setup. 'device_name' can be anything -that can be accessed using the normal UNIX file operations and -produces raw MIDI bytes. Valid devices are for example OSS rawmidi -devices (/dev/midi00), ALSA rawmidi devices (/dev/snd/midiC2D0), named -pipes (see mkfifo man page), and normal files. -

-

-Md:alsaseq,sequencer-port
-Adds a ALSA MIDI sequencer port to the setup. 'sequencer-port' identifies -a port to connect to. It can be numerical (e.g. 128:1), or a client -name (e.g. "KMidimon"). -

-

-Mms:device_id
-Sends MMC start ("Deferred Play") and stop ("Stop") with -device ID 'device_id'. -

-While Ecasound does not directly support syncing transport state -to incoming MMC messages, this can be achieved by connecting Ecasound -to JACK input/outputs, and using a tool such as JackMMC and JackCtlMMC ( -see <http://jackctlmmc.sourceforge.net/>) to convert MMC messages -into JACK transport change events. -

-

-Mss
-Sends MIDI-sync (i.e. "MIDI Start" and "MIDI Stop" system realtime -messages) .to the selected MIDI-device. Notice that as Ecasound will -not send MIDI-clock, but only the start and stop messages. -

-

-

- -EFFECT SETUP -

-PRESETS -

-Ecasound has a powerful effect preset system that allows you create -new effects by combining basic effects and controllers. See -ecasound user's guide for more -detailed information. -

-

-

-

-pf:preset_file.eep
-Uses the first preset found from file 'preset_file.eep' as -a chain operator. -

-

-pn:preset_name
-Find preset 'preset_name' from global preset database and use -it as a chain operator. See ecasoundrc man page for info about the -preset database. -

-

-

-SIGNAL ANALYSIS -

-

-

-

-ev
-Analyzes sample data to find out how much the signal can -be amplified without clipping. The resulting percent value -can be used as a parameter to '-ea' (amplify). A statistical -summary, containing info about the stereo-image and -distribution of sample values, is printed out at the end -of processing. -

-

-evp
-Peak amplitude watcher. Maintains peak information for -each processed channels. Peak information is resetted -on every read. -

-

-ezf
-Finds the optimal value for DC-adjusting. You can use the result -as a parameter to -ezx effect. -

-

-

-GENERAL SIGNAL PROCESSING ALGORITHMS -

-

-eS:stamp-id
-Audio stamp. Takes a snapshot of passing audio data and stores -it using id 'stamp-id' (integer number). This data can later be -used by controllers and other operators. -

-

-ea:amplify%
-Adjusts the signal amplitude to 'amplify%' percent (linear scale, i.e. -individual samples are multiplied by 'amplify%/100'). See also -'-eadb'. -

-

-eac:amplify%,channel
-Amplifies signal of channel 'channel' by amplify-% percent (linear -scale, i.e. individual samples are multiplied by 'amplify%/100'). -'channel' ranges from 1...n where n is the total number of channels. -See also '-eadb'. -

-

-eadb:gain-dB[,channel]
-Adjusts signal level by 'gain-dB', with a gain of 0dB having no effect -to the signal, negative gains attenuating the signal and positive -gain values amplifying it. The 'channel' parameter (1...n) is optional. -If 'channel' parameter is specified, and its value is nonzero, gain is -only applied to the given channel (1...n). -

-

-eaw:amplify%,max-clipped-samples
-Amplifies signal by amplify-% percent (linear scale, i.e. individual -samples are multiplied by 'amplify%/100'). If number of consecutive -clipped samples (resulting sample value is outside the nominal -[-1,1] range), a warning will be issued. -

-

-eal:limit-%
-Limiter effect. Limits audio level to 'limit-%' (linear scale) with -values equal or greater than 100% resulting in no change to -the signal. -

-

-ec:rate,threshold-%
-Compressor (a simple one). 'rate' is the compression rate in -decibels ('rate' dB change in input signal causes 1dB change -in output). 'threshold' varies between 0.0 (silence) and -1.0 (max amplitude). -

-

-eca:peak-level-%, release-time-sec, fast-crate, crate
-A more advanced compressor (original algorithm by John S. Dyson). -If you give a value of 0 to any parameter, the default is used. -'peak-level-%' essentially specifies how hard the peak limiter -is pushed. The default of 69% is good. 'release_time' is given -in seconds. This compressor is very sophisticated, and actually -the release time is complex. This is one of the dominant release -time controls, but the actual release time is dependent on a lot of -factors regarding the dynamics of the audio in. 'fastrate' is the -compression ratio for the fast compressor. This is not really -the compression ratio. Value of 1.0 is infinity to one, while the -default 0.50 is 2:1. Another really good value is special cased in -the code: 0.25 is somewhat less than 2:1, and sounds super smooth. -'rate' is the compression ratio for the entire compressor chain. -The default is 1.0, and holds the volume very constant without many nasty -side effects. However the dynamics in music are severely restricted, -and a value of 0.5 might keep the music more intact. -

-

-enm:threshold-level-%,pre-hold-time-msec,attack-time-msec,post-hold-time-msec,release-time-msec
-Noise gate. Supports multichannel processing (each channel -processed separately). When signal amplitude falls below -'threshold_level_%' percent (100% means maximum amplitude), gate -is activated. If the signal stays below the threshold for -'th_time' ms, it's faded out during the attack phase of -'attack' ms. If the signal raises above the 'threshold_level' -and stays there over 'hold' ms the gate is released during -'release' ms. -

-

-ei:pitch-shift-%
-Pitch shifter. Modifies audio pitch by altering its length. -

-

-epp:right-%
-Stereo panner. Changes the relative balance between the first -two channels. When 'right-%' is 0, only signal on the left -(1st) channel is passed through. Similarly if it is '100', -only right (2nd) channel is let through. -

-

-ezx:channel-count,delta-ch1,...,delta-chN
-Adjusts the signal DC by 'delta-chX', where X is the -channel number. Use -ezf to find the optimal delta -values. -

-

-

-ENVELOPE MODULATION -

-

-

-eemb:bpm,on-time-%
-Pulse gate (pulse frequency given as beats-per-minute). -

-

-eemp:freq-Hz,on-time-%
-Pulse gate. -

-

-eemt:bpm,depth-%
-Tremolo effect (tremolo speed given as beats-per-minute). -

-FILTER EFFECTS -

-

-ef1:center_freq, width
-Resonant bandpass filter. 'center_freq' is the center frequency. Width -is specified in Hz. -

-

-ef3:cutoff_freq, reso, gain
-Resonant lowpass filter. 'cutoffr_freq' is the filter cutoff -frequency. 'reso' means resonance. Usually the best values for -resonance are between 1.0 and 2.0, but you can use even bigger values. -'gain' is the overall gain-factor. It's a simple multiplier (1.0 -is the normal level). With high resonance values it often is useful -to reduce the gain value. -

-

-ef4:cutoff, resonance
-Resonant lowpass filter (3rd-order, 36dB, original algorithm by Stefan -M. Fendt). Simulates an analog active RC-lowpass design. Cutoff is a -value between [0,1], while resonance is between [0,infinity). -

-

-efa:delay-samples,feedback-%
-Allpass filter. Passes all frequencies with no change in amplitude. -However, at the same time it imposes a frequency-dependent -phase-shift. -

-

-efc:delay-samples,radius
-Comb filter. Allows the spikes of the comb to pass through. -Value of 'radius' should be between [0, 1.0). -

-

-efb:center-freq,width
-Bandpass filter. 'center_freq' is the center frequency. Width -is specified in Hz. -

-

-efh:cutoff-freq
-Highpass filter. Only frequencies above 'cutoff_freq' are passed -through. -

-

-efi:delay-samples,radius
-Inverse comb filter. Filters out the spikes of the comb. There -are 'delay_in_samples-2' spikes. Value of 'radius' should be -between [0, 1.0). The closer it is to the maximum value, -the deeper the dips of the comb are. -

-

-efl:cutoff-freq
-Lowpass filter. Only frequencies below 'cutoff_freq' are passed -through. -

-

-efr:center-freq,width
-Bandreject filter. 'center_freq' is the center frequency. Width -is specified in Hz. -

-

-efs:center-freq,width
-Resonator. 'center_freq' is the center frequency. Width is specified -in Hz. Basicly just another resonating bandpass filter. -

-

-

-CHANNEL MIXING / ROUTING -

-

-

-chcopy:from-channel, to-channel
-Copy channel 'from_channel' to 'to_channel'. If 'to_channel' -doesn't exist, it is created. Channel indexing starts from 1. -Option added to ecasound 2.4.5. -

-

-chmove:from-channel, to-channel
-Copy channel 'from_channel' to 'to_channel', and mutes the source -channel 'from_channel'. Channel indexing starts from 1. -Option added to ecasound 2.4.5. -

-

-chorder:ch1,...,chN
-Reorder, omit and/r duplicate chain channels. The resulting -audio stream has total of 'N' channels. Each parameter specifies -the source channel to use for given output channel. As an -example, '-chorder:2,1' would reverse the channels of -a stereo stream ('out1,out2' = 'in2,in1'). Specifying the same -source channel multiple times is allowed. For example, '-chorder:2,2' -would route the second channel to both two output channels -('out1,out2' = 'in2,in2'). If 'chX' is zero, the given channel 'X' -will be muted in the output stream. Option added to ecasound 2.7.0. -

-

-chmix:to-channel
-Mix all source channels to channel 'to_channel'. If 'to_channel' -doesn't exist, it is created. Channel indexing starts from 1. -Option added to ecasound 2.4.5. -

-

-chmute:channel
-Mutes the channel 'channel'. Channel indexing starts from 1. -Option added to ecasound 2.4.5. -

-

-erc:from-channel,to-channel

-

-TIME-BASED EFFECTS -

-

-

-etc:delay-time-msec,variance-time-samples,feedback-%,lfo-freq
-Chorus. -

-

-etd:delay-time-msec,surround-mode,number-of-delays,mix-%,feedback-%
-Delay effect. 'delay time' is the delay time in milliseconds. -'surround-mode' is a integer with following meanings: 0 = normal, -1 = surround, 2 = stereo-spread. 'number_of_delays' should be -obvious. Beware that large number of delays and huge delay times -need a lot of CPU power. 'mix-%' determines how much effected (wet) -signal is mixed to the original. 'feedback-%' represents how much of -the signal is recycled in each delay or, if you prefer, at what rate -the repeated snippet of delayed audio fades. Note that sufficiently -low feedback values may result in a number of audible repetitions -lesser than what you have specified for 'number_of_delays', especially -if you have set a low value for 'mix-%'. By default the value for this -parameter is 100% (No signal loss.). -

-

-ete:room_size,feedback-%,wet-%
-A more advanced reverb effect (original algorithm by Stefan M. Fendt). -'room_size' is given in meters, 'feedback-%' is the feedback level -given in percents and 'wet-%' is the amount of reverbed signal added -to the original signal. -

-

-etf:delay-time-msec
-Fake-stereo effect. The input signal is summed to mono. The -original signal goes to the left channels while a delayed -version (with delay of 'delay time' milliseconds) is goes to -the right. With a delay time of 1-40 milliseconds this -adds a stereo-feel to mono-signals. -

-

-etl:delay-time-msec,variance-time-samples,feedback-%,lfo-freq
-Flanger. -

-

-etm:delay-time-msec,number-of-delays,mix-%
-Multitap delay. 'delay time' is the delay time in milliseconds. -'number_of_delays' should be obvious. 'mix-%' determines how much -effected (wet) signal is mixed to the original. -

-

-etp:delay-time-msec,variance-time-samples,feedback-%,lfo-freq
-Phaser. -

-

-etr:delay-time,surround-mode,feedback-%
-Reverb effect. 'delay time' is the delay time in milliseconds. -If 'surround-mode' is 'surround', reverbed signal moves around the -stereo image. 'feedback-%' determines how much effected (wet) -signal is fed back to the reverb. -

-

-

-LADSPA-PLUGINS -

-

-el:plugin_unique_name,param-1,...,param-N
-Ecasound supports LADSPA-effect plugins (Linux Audio Developer's Simple -Plugin API). Plugins are located in shared library (.so) files in -/usr/local/share/ladspa (configured in ecasoundrc man page). One shared -library file can contain multiple plugin objects, but every plugin -has a unique plugin name. This name is used for selecting plugins. -See LAD mailing list web site for -more info about LADSPA. Other useful sites are LADSPA home -page and LADSPA -documentation. -

-

-eli:plugin_unique_number,param-1,...,param-N
-Same as above expect plugin's unique id-number is used. It -is guaranteed that these id-numbers are unique among all -LADSPA plugins. -

-

-

-GATE SETUP -

-

-

-

-gc:start-time,len
-Time crop gate. Initially gate is closed. After 'start-time' seconds -has elapsed, gate opens and remains open for 'len' seconds. When -closed, passing audio buffers are trucated to zero length. -

-

-ge:open-threshold-%,close-thold-%,volume-mode,reopen-count
-Threshold gate. Initially gate is closed. It is opened when volume -goes over 'othreshold' percent. After this, if volume drops below -'cthold' percent, gate is closed and won't be opened again, unless the -'reopen-count' is set to anything other than zero. -If 'value_mode' is 'rms', average RMS volume is used. Otherwise -peak average is used. When closed, passing audio buffers are trucated -to zero length. -If the 'reopen-count' is set to a positive number, then the gate will -restart its operation that many times. So for example, a reopen count -of 1 will cause up to 2 openings of the gate. A negative value for 'reopen-count' -will result in the gate reopening indefinitely. The 'reopen-count' is invaluable -in recording vinyl and tapes, where you can set things up and then recording -starts whenever the needle is on the vinyl, and stops when it's off. As many sides -as you like can be recorded in one session. You will need to experiment with -buffer lengths and start/stop levels to get reliable settings for your equipment. -

-

-gm:state
-Manual gate. If 'state' is 1, gate is open and all samples are -passed through. If 'state' is zero, gate is closed an no samples are -let through. This chain operator is useful when writing to an output -needs to be stopped dynamically (without stopping the whole engine). -

-

-

- -CONTROL ENVELOPE SETUP -

-

-Controllers can be used to dynamically change effect parameters -during processing. All controllers are attached to the selected -(=usually the last specified effect/controller) effect. The first -three parameters are common for all controllers. 'fx_param' -specifies the parameter to be controlled. Value '1' means -the first parameter, '2' the second and so on. 'start_value' -and 'end_value' set the value range. For examples, look at the -the EXAMPLES section. -

-

-kos:fx-param,start-value,end-value,freq,i-phase
-Sine oscillator with frequency of 'freq' Hz and initial phase -of 'i_phase' times pi. -

-

-kog:fx-param,freq,mode,point-pairs,start-value,end-value,pos1,value1,...
-Generic oscillator. Frequency 'freq' Hz, mode either '0' for -static values or '1' for linear interpolation. 'point-pairs' -specifies the number of 'posN' - 'valueN' pairs to include. -'start-value' and 'end-value' are used as border values. -All 'posN' and 'valueN' must be between 0.0 and 1.0. Also, -for all 'posN' values 'pos1 < pos2 < ... < posN' must be true. -

-

-kf:fx-param,start-value,end-value,freq,mode,genosc-number
-Generic oscillator. 'genosc_number' is the number of the -oscillator preset to be loaded. Mode is either '0' for -static values or '1' for linear interpolation. The location for -the preset file is taken from ./ecasoundrc (see ecasoundrc man page). -

-

-kl:fx-param,start-value,end-value,time-seconds
-Linear envelope that starts from 'start_value' and linearly -changes to 'end_value' during 'time_in_seconds'. Can -be used for fadeins and fadeouts. -

-

-kl2:fx-param,start-value,end-value,1st-stage-length-sec,2nd-stage-length-sec
-Two-stage linear envelope, a more versatile tool for doing fade-ins -and fade-outs. Stays at 'start_value' for '1st_stage_length' seconds -and then linearly changes towards 'end_value' during -'2nd_stage_length' seconds. -

-

-klg:fx-param,low-value,high-value,point_count,pos1,value1,...,posN,valueN
-Generic linear envelope. This controller source can be -used to map custom envelopes to chain operator parameters. Number of -envelope points is specified in 'point_count'. Each envelope point -consists of a position and a matching value. Number of pairs must -match 'point_count' (i.e. 'N==point_count'). The 'posX' parameters are given -as seconds (from start of the stream). The envelope points are specified as -float values in range '[0,1]'. Before envelope values are mapped to operator -parameters, they are mapped to the target range of '[low-value,high-value]'. E.g. -a value of '0' will set operator parameter to 'low-value' and a value of -'1' will set it to 'high-value'. For the initial segment '[0,pos1]', the envelope -will output value of 'value1' (e.g. 'low-value'). -

-

-km:fx-param,start-value,end-value,controller,channel
-MIDI continuous controller (control change messages). -Messages on the MIDI-channel 'channel' that are coming from -controller number 'controller' are used as the controller -source. As recommended by the MIDI-specification, channel -numbering goes from 1 to 16. Possible controller numbers -are values from 0 to 127. The MIDI-device where bytes -are read from can be specified using -Md option. -Otherwise the default MIDI-device is used as specified in -~ecasound/ecasoundrc (see ecasoundrc man page). -Defaults to /dev/midi. -

-

-ksv:fx-param,start-value,end-value,stamp-id,rms-toggle
-Volume analyze controller. Analyzes the audio stored in -stamp 'stamp-id' (see '-eS:id' docs), and creates -control data based on the results. If 'rms-toggle' is non-zero, -RMS-volume is used to calculate the control value. Otherwise -average peak-amplitude is used. -

-

-kx
-This is a special switch that can be used when you need -to control controller parameters with another controller. -When you specify -kx, the last specified controller -will be set as the control target. Then you just add -another controller as usual. -
-

- -INTERACTIVE MODE -

-See ecasound-iam(1) man page. -

-

ENVIRONMENT

-

-

-

ECASOUND
- If defined, some utility programs and scripts will use - the ECASOUND environment as the default path to - ecasound executable. -

-

ECASOUND_LOGFILE
- Output all debugging messages to a separate log file. If defined, - ECASOUND_LOGFILE defines the logfile path. This is a good tool for - debugging ECI/EIAM scripts and applications. -

-

ECASOUND_LOGLEVEL
- Select which messages are written to the logfile defined by - ECASOUND_LOGFILE. The syntax for -d:level is used. If not - defined, all messages are written. Defaults to -d:319 (everything else - but 'functions (64)' and 'continuous (128)' class messages). -

-

COLUMNS
- Ecasound honors the COLUMNS environment variable when - formatting printed trace messages. If COLUMNS is not set, - a default of 74 is used. -

-

TMPDIR
- Some functions of Ecasound (e.g. "cs-edit" interactive command) require - creation of temporary files. By default, these files are created under - "/tmp", but this can be overridden by setting the TMPDIR environment - variable. -
-

-

RETURN VALUES

-

-In interactive mode, ecasound always returns zero. -

-In non-interactive (batch) mode, a non-zero value is returned - for the following errors: -

-

-

1
- Unable to create a valid chainsetup with the given parameters. Can be - caused by invalid option syntax, etc. -

-

2
- Unable to start processing. This can be caused by insufficient file - permissions, inability to access some system resources, etc. -

-

3
- Error during processing. Possible causes: output object has run - out of free disk space, etc. -

-

4
- Error during process termination and/or cleanup. See section - on 'SIGNALS' for further details. -

-

SIGNALS

-

-When ecasound receives any of the POSIX signals SIGINT (ctrl-c), - SIGHUP, SIGTERM or SIGQUIT, normal cleanup and exit procedure is - initiated. Here normal exit means that e.g. file headers are - updated before closing, helper processes are terminated in normal - way, and so forth. -

-If, while doing the cleanup described above, ecasound receives - another signal (of the same set of POSIX signals), ecasound - will skip the normal cleanup procedure, and terminate - immediately. Any remaining cleanup tasks will be skipped. - Depending on the runtime state and configuration, this brute - force exit may have some side-effects. Ecasound will return - exit code of '4' if normal cleanup was skipped. -

-Special case handling is applied to the SIGINT (ctrl-c) signal. - If a SIGINT signal is received during the cleanup procedure, - ecasound will ignore the signal once, and emit a notice to 'stderr' - that cleanup is already in progress. Any subsequent SIGINT signals - will no longer get special handling, and instead process will - terminate immediately (and possibly without proper cleanup). -

-

FILES

-

-~/.ecasound - The default directory for ecasound user resource files. - See the ecasoundrc (5) man page man page. -

-*.ecs - Ecasound Chainsetup files. Syntax is more or less the - same as with command-line arguments. -

NAME

ecasoundrc - ecasound rcfile -

-

SYNOPSIS

- {prefix}/share/ecasound/ecasoundrc (for instance '/usr/local/share/ecasound/ecasoundrc') - $HOME/.ecasound/ecasoundrc -

-

DESCRIPTION

-

-ecasoundrc is the main configuration file for ecasound. - Any user-specific modification should be done to - $HOME/.ecasound/ecasoundrc, not to the global resource file. Ecasound - also allows to disable the normal policy and only read from a specific - resource file (see ecasound (1) and documentation for the -R option). -

-The format is quite simple. One line consists of - a configuration variable and its value. Variable and value - are separated with either '=' or ' '. Lines beginning with a - "#" are ignored (comment lines). -

-

VARIABLES

-

-

-

-

midi-device
- MIDI-device. If the device name is given in rawmidi,/dev/midi* - format, OSS/Linux or OSS/Lite drivers are used. - Device rawmidi,/dev/snd/midiCxDy opens an ALSA raw-MIDI - device with card number 'x' and device number 'y'. - See ecasound (1) man page (the '-Md option) for more info. - Defaults to rawmidi,/dev/midi. -

-

default-output
- Output device to use by default. If a chainsetup with zero - outputs, but with one or more inputs, is connected, a default output - is added and all the chains are connected to it. If the special-case - value 'autodetect' is specified, ecasound will try to auto-detect - a suitable device (JACK -> ALSA -> OSS -> rtnull). - Defaults to autodetect. -

-

default-audio-format
- Default values for sample format, channel count, sampling rate - and channel interleaving. Syntax is the same as used by - ecasound's -f option (see ecasound (1)). - Defaults to s16_le,2,44100,i. -

-

default-to-precise-sample-rates
- Whether to ignore sample rate differences (and possibly avoid - resampling). Currently only affects OSS-devices. Defaults to false. -

-

default-mix-mode
- If default-mix-mode is sum, engine will mix multiple channels into - one output channel by summing all input channels. In mode avg, - mixing is done by taking the average of all input channels. The - avg mode is safe from clipping, while sum is closer - to the way analog mixers work. Defaults to avg. -

-

bmode-defaults-nonrt
- Selects the default parameters to use with buffering - mode 'nonrt' (other modes are 'rt' and 'rtlowlatency). - Parameters are given as a comma-separated tuple of values: - 1) buffersize (number,-b), 2) raised priority (true/false,-r), - 3) sched_priority (number,-r:X), 4) double buffering - (true/false,-z:db), 5) db-bufsize (number,-z:db,X), and - 6) max intbuf (true/false,-z:intbuf). Defaults to - 1024,false,50,false,100000,true. -

-

DESCRIPTION

-

-Ecatools are simple command line utils for audio file processing. -Each tool is designed to perform one specific operation. Most of -the tools also support batch processing. -

-ECACONVERT -

-A tool for converting a set of files to a common target format. -This target format is given as the first command line -argument, and its syntax is .ext. -

-ECAFIXDC -

-A simple command-line tool for fixing DC-offset. -

-ECALENGTH -

-See the separate ecalength(1) man page. -

-ECAMONITOR -

-Ecamonitor is a util program that can be used -to monitor an active ecasound session. Ecamonitor -is able to show information about the current -chainsetup such as list of inputs, outputs, -current position, effects, the engine status -and numerous other things. -

-By default ecamonitor will try to connect -to IP4 address "localhost", to port "2868". -A different address can be specified when -starting ecamonitor, for example -"ecamonitor foo.mynetwork.com" or -"ecamonitor foo.mynetwork.com:4500". -

-To enable inbound connections, ecasound has to be -started with the --daemon option. Ecamonitor is -implemented in Python using the NetECI API. -

-ECANORMALIZE -

-Ecanormalize is a command-line tool for normalizing audio -files to utilize the full available sample resolution. Ecanormalize -first finds out how much the input file can be amplified without -clipping and if there is room for increase, a static gain will -be applied to the file. -

-ECAPLAY -

-Ecaplay is a command-line tool for playing audio files. Ecaplay -uses the libecasound engine and is thus able to handle all audio formats -supported by the library. -

-Files can be selected for playback either by specifying the -filenames on the command-line, or by using the playlist -mechanism. In playlist mode, files can be added to the playlist -using the -q option. The -p option can then be used -to play all tracks on the playlist. Ecaplay will repeat the -playlist tracks until explicitly stopped (with double Ctrl-C). -Playlist can be flushed with -f and its contents listed -with -l option. -

-If not otherwise specified, ecaplay will use the audio output device -specified in ~/.ecasound/ecasoundrc for playback. A different -output device can be selected with ECAPLAY_OUTPUT_DEVICE shell -environment variable or with the -o:output_device command-line -option. -

-Playback can be stopped at any time with Ctrl-C. If multiple -files are played, first Ctrl-C will stop the current file and move -on to play the next one. Issuing Ctrl-C twice (within one second), -will cause ecaplay to exit. -

-

-

-d:debuglevel
-Set libecasound debug level. See ecasound(1). -

-

-f
-Flush the playlist contents. See also -options -l, -p and -q. -

-

-h
-Print usage information and exit. -

-

-k:number
-Skip 'number' of files. -

-

-l
-List the current playlist contents to stdout. See also -options -f, -p and -q. -

-

-o:output_device
-Use 'output_device' instead of the default output device -(as specified in ~/.ecasound/ecasoundrc). Syntax is same -as used by "-o" ecasound option (see ecasound(1) man page). -This option overrides the ECAPLAY_OUTPUT_DEVICE environment -variable (more info below). -

-

-p
-Play tracks in the playlist (in looped mode). See also -options -f, -l and -q. -

-

-q
-Queue new tracks to the playlist. All filenames given on -the command-line will be added to the the playlist. It is -possible to queue new tracks while another instance of -ecaplay is using the playlist. See also options -f, -l -and -p. -

-

-

-ECASIGNALVIEW -

-Ecasignalview is meant for monitoring signal amplitude and peak -statistics. It accepts the following options: -

-

-

input
-The first option not starting with a '-' is interpreted -as an input string. This can be a device or a filename. All formats -supported by libecasound are accepted. Defaults to '/dev/dsp'. -

-

output
-Similarly to input, second option not starting with a '-' -is interpreted as output. Defaults to 'null'. -

-

-b:buffersize
-Buffersize in sample frames. Defaults to 128. -

-

-c
-Enable cumulative mode. Counters are not reseted after refresh. -*deprecated* -

-

-d
-Enable debug mode. -

-

-f:format_string
-Specify default audio format. See ecasound(1) for details. -

-

-r:rate_msec
-Specify screen refresh rate in milliseconds. -

-

-I
-Use linear scale for showing audio sample amplitude. -

-

-L
-Use logarithmic scale for showing audio sample amplitude. -

-

-G, -B, -M*, -r, -z
-Ecasound options use to modify the engine behaviour, see -ecasound(1) manpage for details. -

-

-

-When ecasignalview is running, the following keyboard -commands can be used to control the operation (requires -system support for UNIX terminal interface control): -

-

-

spacebar
-Reset statistics (max-peak, avg-amplitude and clipped -samples count). -

-

q or Q or Esc
-Quit ecasignalview. -

-

-

-It is also possible to reset the max-peak and clipped-samples -counters by sending a SIGHUP signal to the process (i.e. -from another console: "killall -v -HUP ecasignalview"). -

-More complete documentation for ecasignalview can be found -from "Ecasound User's Guide" (see ''http://www.eca.cx/ecasound --> Documentation''). -

-

ENVIRONMENT

-

-ECASOUND - Path to the ecasound executable. Used by many ecatools. -

-ECAPLAY_OUTPUT_DEVICE - Device ecaplay should use for audio output. Same syntax - as for ecaplay/ecasound "-o" option. -

-

FILES

-

-~/.ecasound/ecasoundrc - The default ecasound resource file. See ecasoundrc(5) - for details. -

-~/.ecasound/ecaplay_queue - File used to store the ecaplay playlist (one track per - line with full path). -

At same time -overuse of object-orientation should be avoided. Object-orientation is -a very effective design method, but not the only one. Sometimes other -approaches work better. - -Data hiding ------------ - -This design principle deserves to be mentioned separately. Whenever -possible, the actual data representation and implementation details -should always be hidden. This allows to make local implementation -changes without affecting other parts of the code base. It cannot -be emphasized enough how important this goal is for large software -projects like Ecasound. - -Design by contract ------------------- - -When writing a new routine, in addition to the actual code, -also routine's behaviour should be described as accurately as -possible using preconditions and postconditions to describe -the external side-effects (how it changes the object state, what -is the relation between arguments and return values). - -The preconditions should specify all requirements and -assumptions related to routine's inputs. If the caller violates -this specification, routine is not responsible for the error. - -The postconditions should specify what statements hold true -when routine has been executed. This information helps the -caller to better understand how the routine works and -to identify implementation bugs. - -Ideally, these conditions prove that the routine works -correctly. Writing a complete description of a routine can be -difficult, but the benefits of this approach should be clear. -When you call a well-defined routine, a) you know what -parameter values it accepts, b) you know what it does and c) if -errors occur, it's easier to pinpoint the faulty routine. - -In practice describing routines is done by combining verbose -comments and defining pre/postconditions. As C++ doesn't directly -support pre/postconditions, the DEFINITION_BY_CONTRACT and DBC tools -provided by libkvutils are used. - -Routine side effects --------------------- - -A clear distinction should be made between routines that -have side-effects (=methods, processors, modifiers; routines that -change object's state) and const routines (=functions, observers). - -To make monitoring side effects easier, all Ecasound classes -should be const-correct. A object is const-correct if a function -taking only a single argument that is a const reference to that object -is not able, without explicit casting, to obtain a non-const -reference to that same object (or a portion thereof) from within -the function body. - -Sanity checks -------------- - -Sanity checks are done only to prevent crashes. All effects -and operators should accept also "insane" parameters. For example, -the amplifier effect accepts -100.0% as the gain value. This of course -results in inverted sample data, which is a useful outcome. -As Ecasound is supposed to be a tool for creative work and -experimenting, the decisions on which parameters are useful -for audio processing should not be made in source code. - -Error handling --------------- - -Two specific things worth mentioning: First, the standard UNIX-style -error handling, where functions performing actions return an integer -value, is not used in Ecasound. As described in the above section -Routine side effects, all routines are either modifiers or -observers, not both. So when using Ecasound APIs, you first perform an -action (modifying function), and then afterwards check what happened -(using an observer function). - -Exceptions ----------- - -C++ exceptions are used in Ecasound. Exception based error -handling has its problems, but in some cases it is clearly the best -option. Exceptions are most useful in situations where -controlled error recovery is very difficult, and in situations -where errors occurs only very rarely. This allows callers to -avoid constantly checking returns values for functions that -in normal use never fail. Another special case is handling critical -errors that occur in class contructors. - -Using exceptions for anything other than pure error handling -is to be avoided at all cost. And when exceptions are used, -their use must be specified in function prototypes. This is important, -as clients need to know what exceptions can be thrown. C++ -unfortunately doesn't require strict exception prototypes, so -this issue requires extra care. - -A list of specific cases where exceptions are used follows: - -AUDIO_IO - open() - This method is used for initializing external connections (opening - files or devices, loading shared libraries, opening IPC connections). - It's impossible to know in advance what might happen. In many cases it - is also useful to get more verbose information about the problem - that caused open() to fail. Throwing an exception is an excellent way - to achieve this. - -ECA_CHAINSETUP - enable() - TBD - -ECA_CHAINSETUP - load_from_file, save() and save_to_file - TBD - -ECA_SESSION - constructor - TBD - - -Coding style, naming conventions and source code markup -======================================================= - -This section describes some of the conventions used in -Ecasound development. As a general rule, one should -adapt to whatever style and conventions used in -already existing code. - -Variable and type naming ------------------------- - -Variable names are all lower case and words are separated with -underscores (int very_long_variable_name_with_underscores). Class data -members are marked with "_rep" postfix. Data members which are -pointers are marked with "_repp". Index-style short variable names -(n, m, etc.) are only used in local scopes. Enum types -have capitalized names (Some_enum). - -Use of macro processing should be avoided, but when necessary, -macro names should be capitalized. - -Package specific ----------------- - -libecasound, ecasound, ecatools, libkvutils - Class names are all in upper case and words separated with underscores - (class ECA_CONTROL_BASE). This a standard style in Eiffel programming. - -libqtecasound, qtecasound, ecawave - Qt-style is used when naming classes (class QELevelMeter), otherwise - same as above. - -Private classes ---------------- - -Some classes are divided into public and private parts. This is -done to make it easier to maintain binary-level compatibility -between library versions, and to get rid of header file -dependencies. - -Private classes have a "_impl" postfix in their name. They -are usually stored into separate files which also use the -"_impl" notation. - -For instance the ECA_ENGINE class (eca-engine.h) has -a private class ECA_ENGINE_impl (eca-engine_impl.h). -Access to ECA_ENGINE_impl is only allowed to ECA_ENGINE -member functions. In addition, the private header file -(eca-engine_impl.h) is only included from the ECA_ENGINE -implementation file (eca-engine.cpp). This allows us to -add new data members to ECA_ENGINE_impl without breaking -the binary interface. - -Unit tests ----------- - -Unit tests are used for verifying that modules work as intended. -A test for component, with a public interface defined in -"prefix-component.h", should located in -"prefix-component_test.h". The test itself should implement -the ECA_TEST_CASE interface. In addition, generic test cases -should be added to ECA_TEST_REPOSITORY - see -"libecasound/eca-test-repository.cpp". - -Source code markup ------------------- - -In addition to the Javadoc-style source code documentation (see -'Documentation style' section), inline commentary markup is used -to document important code segments. Use of common markup notation -is preferred (for example it is nice to be able to grep for a list -of open items in certain part of the codebase): - -- Known bugs, unhandled cases, and missing features should - be marked with "FIXME: description" comments. - -- Explanatory notes that help to understand the code - should be marked with "NOTE: description". - -Style updates -------------- - -The general rule is to use consistant style within one -source file (i.e. compilation unit). Updates to style issues -are also done with the same granularity. The following global -updates have been made so far to the sources: - -eca-style-version: 1 - The opening braces of multi-line functions should be put on a separate - line, at column 1, instead of being on the same line with - function signature. This change only applies to functions, in - other words the K&R style is followed. - -eca-style-version: 2 - Extra parenthesis around "return" values should be removed - ("return" is a keyword, not a function). - -eca-style-version: 3 - The module name prefix, for example "(eca-session) ", should - be removed from ECA_LOG_MSG() statements. The module prefix - is added automatically to the debug messages when debug - level "module_names" is activated. - -If a file has been updated according to these guidelines, -the appropriate style version should be mentioned at the -start of the file ("Attributes: eca-style-version: XXX"). - - -Physical level organization -=========================== - -Ecasound libraries and applications are divided into distribution -packages, directories and file groups. - -Include hierarchies -------------------- - -Include statements that are not stricly necessary should be dropped! -Not only do they cause unwanted dependencies, they also create more -work for the compiler (Ecasound already takes painfully long to -compile). Some rules to follow: - -- In header files, no extra header files should be defined. - For instance in many cases it's enough to state that - object SOME_TYPE is a class without need for the full - implementation; so instead of "\#include "sometype.h", use - "class SOME_TYPE;". - -- For modules with separate implementation and header files, - dependencies to other modules need not be - stated in both. - -- Direct dependencies to outside modules must always - be mentioned directly. It's easy to unknowingly include - a required header file via some other header file. This - should be avoided as it hides real dependencies. - -- When including headers for more special services, it's - good to add a comment why this header file is needed. - -Distribution packages ---------------------- - -As an example, Ecasound and Ecawave are distributed as separate -packages. This decision has been made because a) they are clearly -independent, b) they have different external dependencies, and c) -they address different target uses. - -Directories ------------ - -It's convenient to organize larger sets of source code into separate -directories. For instance libecasound and ecatools components of -the Ecasound package are located in separate directories. - -File groups ------------ - -Although files are divided in directories and subdirectories, -there's still a need to logically group a set of source files based -on their use and role in the overall design. As the use of C++ -namespaces is very limited in Ecasound (to avoid portability -problems), filename prefixes are used for grouping files. Here's -a short list of commonly used prefixes. - -audioio*.{cpp,h} - Audio device and file input/output. -audiofx*.{cpp,h} - Audio effects and other DSP-related code. -audiogate*.{cpp,h} - Gate operators. -eca*.{cpp,h} - Core functionality. -midi*.{cpp,h} - MIDI input/output devices, handlers and controller code. -osc*.{cpp,h} - Oscillator and other controller sources. -qe*.{cpp,h} - Generic prefix for files utilizing both Qt and Ecasound libraries. -samplebuffer*.{cpp,h} - Routines and helper functions for processing audio data buffers. - -You should note that these are just recommendations - there are no -strict rules on how files should be named. - -C++ std namespace ------------------ - -The preferred way to access C++ standard library functions is -to use explicit namespace selectors ("std::string") in public -headers files, and "using declarations" in the implementation -parts ("using std::string"). It's also possible to import the -whole std namespace ("using namespace std;") in the beginning -of an implementation file (but never in headers!). - - -Documentation style -=================== - -Javadoc-style class documentation is the preferred style. -Class members can be documented either when they are declared (header -files), or when they are defined. Especially when specifying -complicated interfaces, it's better to put documentation in the -definition files. This way the header files remain compact and serve -better as a reference. - -Here's a few general documentation guide lines: - -Use of 3rd person - "Writes samples to memory." instead of "Write samples to memory." -Sentences start with a verb - "Writes samples to memory." instead of "Samples are written to memory." -Use "this" instead of "the" - "Get controllers connected to this effect." instead of "Get controllers connected to the effect. - - -Versioning -========== - -All Ecasound releases have a distinct version number. The -version number syntax is x.y[.z][-extraT], where x and -y are the major and minor numbers, and z is an optional -revision number. To test major changes, separate -preX or --rcX versions can be distributed before the official release. - -In addition, all Ecasound libraries have a separate interface -version. The libtool-style version:revision:age versioning -is used. See the libtool documentation for details. - -One important thing to note is that the library interface version -numbers are tied to the source-code level interfaces, not the binary -interfaces. Because binary interfaces are not explicitly versioned, -applications should always statically link against the Ecasound -libraries. Also, any private source-code interfaces, ie. header -files with a "_impl.h" postfix, are not part of the versioned -public interface. Applications should not rely on these interfaces! - -All changes in the public interfaces are documented in library -specific ChangeLog files. These files are usually located in the -top-level source directory of the versioned library. - -One thing to note is that Ecasound's versioning practises have -changed quite a few times during the project's history. The -rules described above only apply to Ecasound 2.2.0 and newer -releases. - -.. ################################################################# -.. ################################################################# - -How Ecasound works? -~~~~~~~~~~~~~~~~~~~ - -Example use cases -================= - -Here's a few common use cases how Ecasound can be used. - -Simple non-interactive processing ---------------------------------- - -One input is processed and then written to one output. This includes effect -processing, normal sample playback, format conversions, etc. - -Multitrack mixing ------------------ - -Multiple inputs are mixed into one output. - -Real-Time effect processing ---------------------------- - -There's at least one real-time input and one real-time output. -Signal is sampled from the real-time input, processed and -written to the real-time output. - -One-track recording -------------------- - -One real-time input is processed and written to one or -more outputs. - -Multitrack recording --------------------- - -The most common situation is that there are two separate -chains. First one consists of real-time input routed to a -non-real-time output. This is the recording chain. The -other one is the monitor chain and it consists of one or -more non-real-time inputs routed to a real-time output. -You could also route your real-time input to the monitoring -chain, but this is not recommended because of severe -timing problems. To synchronize these two separate chains, -Ecasound uses a special multitrack mode (which should be -enabled automatically). - -Recycling a signal through external devices -------------------------------------------- - -Just like multirack recording. The only difference is -that real-time input and output are externally -connected. - - -Audio signal routing -==================== - -Basic audio flow inside an Ecasound chainsetup is as follows: Audio -data is routed from input audio objects to a group of chains. In -the chains audio data is processed using chain operators. After -processing data is routed to output objects. - -Using internal loop devices, it's also possible to route signals -from one chain to another. Looping causes extra latency of one -engine cycle. - -Routing of signals is based on the ability to assign inputs and -outputs to multiple chains. Assigning an input object to multiple -chains divides the audio signal generating multiple copies of -the original input data. Similarly with an output object, data from -multiple chains is mixed together to one output object. - -Control flow -============ - -Batch operation ---------------- - -When Ecasound is run in batch mode, the program flow is simple. -To store the session data, a ECA_SESSION object is first -created. The created object is then passed as an argument for -ECA_CONTROL class constructor. - -All required configuration of inputs, outputs and chain -operators is done using the services provided by ECA_CONTROL. -Once a valid chainsetup is ready for processing, batch -operation is initiated by issuing ECA_CONTROL::run(). This -function will block until processing is finished. - -Interactive operation ---------------------- - -Interactive operation is similar to batch operation. The -important difference is that processing is started with -ECA_CONTROL::start(). Unlike run(), start() does not -block the calling thread. This makes it possible to -continue using the ECA_CONTROL interface while engine -is running in the background. - -Two important concepts to understand when -working with ECA_CONTROL are the selected -and connected chainsetups. ECA_CONTROL allows -working with multiple chainsetups, but only one -of them can be edited at a time, and similarly -only one at a time can be connected to the -processing engine. For instance if you add a new -input object with add_audio_input(), it is -added to the selected chainsetup. Similarly when -you issue start(), the connected chainsetup is -started. - -.. ################################################################# -.. ################################################################# - -Library organization -~~~~~~~~~~~~~~~~~~~~ - -The primary source for class documentation is header files. -A browsable version of header documentation is at -http://www.eca.cx/ecasound/Documentation -Anyway, let's look at the some central classes. - - -Interfaces for external use -=========================== - -The following classes of libecasound are designed as -primary interfaces for external use. The approach -is based on the Facade (GoF185) design pattern. The primary -goals are concentrating functionality, and maintaining -a higher level of interface stability. - -ECA_CONTROL - eca-control.h ---------------------------- - -ECA_CONTROL represents the whole public interface offered by -libecasound. The primary purpose of ECA_CONTROL is to offer a -consistent, straightforward interface for controlling Ecasound. -The interface is also designed to be more stable than other -parts of the library. - -On important part of ECA_CONTROL is the functionality for -interpreting EOS (Ecasound Option Syntax) and EAIM (Ecasound -Interactive Mode) commands. - -ECA_CONTROL_MAIN (eca-control-main.h) is an abstract base class that -defines a subset of core ECA_CONTROL functionality. This interface -is implemented by e.g. ECA_CONTROL (the default implementation) -and ECA_CONTROL_MT (a thread-safe variant that allows simultaneous -use from multiple threads). - -It is recommended that applications use the subset defined -by ECA_CONTROL_MAIN. - -ECA_CONTROL_INTERFACE - eca-control-interface.h ------------------------------------------------ - -C++ implementation of the Ecasound Control Interface (ECI) API. See -section "Ecasound Control Interface" for more information. - -Core classes -============ - -This section introduces the core classes, which define the -central data types and are responsible for the main program -logic. - -AUDIO_IO_PROXY_SERVER - audioio-proxy-server.h ----------------------------------------------- - -Implements a audio input/output subsystem that adds -a second layer of buffering between the main processing -engine and non-real-time audio input and output objects. - -Double buffering is needed to guarantee a real-time constrained -data stream even when dealing with non-real-time objects like -disk files. - -CHAIN - eca-chain.h -------------------- - -Class representing one abstract audio signal chain. CHAIN -objects consist of chain operators, controllers and their -state information. - -ECA_CHAINSETUP - eca-chainsetup.h ---------------------------------- - -ECA_CHAINSETUP is the central class for storing user-visible -objects. All inputs, output, chain operator and controller -objects are attached to some ECA_CHAINSETUP object. - -ECA_ENGINE - eca-engine.h -------------------------- - -ECA_ENGINE is the actual processing engine. It is initialized with -a pointer to a ECA_CHAINSETUP object, which has all information -needed at runtime. In other words ECA_ENGINE is used to execute -the chainsetup. You could say ECA_ENGINE renders the final product -according to instruction given in ECA_CHAINSETUP. - -Processing is started with the exec() member function and -after that, ECA_ENGINE runs on its own. If 'batch_mode' -is selected (parameter to exec()), one started ECA_ENGINE will -run until a 'finished' condition is met and then exit -automatically. Finished means that we have read all available data -from input sources. Of course if some input has infinite length -(soundcards for example), processing will never finish. To get -around this limitation, it's possible to set the processing -length (see ECA_CONTROL_OBJECTS::set_chainsetup_processing_length_in_seconds()). - -If batch mode is not enabled, engine will just perform -the init phase and starts waiting for further instructions. -These instructions can be send to the engine using -the ECA_ENGINE::command() member function. - -ECA_ENGINE has the following states: - -not_ready - ECA_SESSION object is not ready for processing or - ECA_ENGINE hasn't been created -running - processing -stopped - processing hasn't been started or it has been stopped - before completion -finished - processing has been completed -error - an error has occured during prosessing - -ECA_SESSION - eca-session.h ---------------------------- - -ECA_SESSION is an abtraction used to represents a group of -chainsetups. At any time, only one chainsetup object at a time -can be active (connected). For modification, one chainsetup -can be set as 'selected'. This means that all configuration -operations are targeted to the selected chainsetup. - -The only public access to ECA_SESSION objects is -through ECA_CONTROL objects. - -MIDI_SERVER - midi-server.h ---------------------------- - -Engine that handles all MIDI input and output. - -SAMPLEBUFFER - samplebuffer.h ------------------------------ - -Basic unit for representing blocks of sample data. The data type used -to represent single samples, valid value ranges, channel count and system -endianess are all specified in "samplebuffer.h" and "sample_specs.h". - - -Feature and capability interface classes -======================================== - -Many libecasound classes have similar attribute sets and capabilities. -To make use of these shared features, most common features have their -own virtual base classes. All objects that have a particular feature, -inherit the same virtual base class. This makes object grouping -and management easier and less error prone. - -DYNAMIC_PARAMETERS - dynamic-parameters.h --------------------------------------------- - -Implemented by all classes that provide a set of generic parameters -of type T. Parameter can be observed and modified, and they -usually are identified by a unique name and a more verbose -description. Number of parameters can vary dynamically. Other -objects can access these parameters without detailed knowledge of -the object itself. - -ECA_AUDIO_FORMAT - eca-audio-format.h -------------------------------------- - -Implemented by all classes that an audio format attribute -set that can be observed and modified. - -ECA_AUDIO_POSITION - eca-audio-position.h ------------------------------------------ - -Implemented by all classes that need to maintain current audio -position and length. - -ECA_SAMPLERATE_AWARE - eca-samplerate-aware.h ---------------------------------------------- - -Implemented by all classes that need knowledge of current -sampling rate. - -MIDI_CLIENT - midi-client.h ---------------------------- - -Implemented b all classes that require a connection to -an instance of MIDI_SERVER. - - -Object interfaces -================= - -Object interfaces define the behaviour for common objects used -by libecasound. The core classes rarely operate on specific -object types, but instead use object interfaces (abstract -interfaces). Object interfaces are usually abstract C++ classes -(instances of these classes cannot be created as some of functions -don't yet have a concreate implementation, ie. they pure virtual -functions). - -AUDIO_IO - audioio.h --------------------- - -Virtual base class for all audio I/O objects. Different types -of audio objects include files, audio devices, sound -producing program modules, audio server clients, and so on. - -More specialized interface classesa are AUDIO_IO_DEVICE (for -real-time audio objects) and AUDIO_IO_BUFFERED (for POSIX-style -buffered i/o). There's also a special AUDIO_IO_MANAGER -interface for managing multiple audio objects of same -type inside one chainsetup. - -CHAIN_OPERATOR - eca-chainop.h ------------------------------- - -Virtual base class for chain operators. - -CONTROLLER_SOURCE - ctrl-source.h ---------------------------------- - -Virtual base class for all controller sources. - -MIDI_IO - midiio.h ------------------- - -Virtual base for objects capable of reading and writing -raw MIDI data. - -MIDI_HANDLER - midi-server.h ----------------------------- - -Virtual base class for objects capable of receiving -and processing MIDI data. - -Object interface implementations - plugins -========================================== - -Majority of the classes in libecasound fall to this category. They -implement the behaviour of some object interface type. As other -parts of the library only use the object interfaces, these -implementation classes are fairly isolated. Changes made inside object -implementation have no effect to other parts of the library. -Similarly new object interface implementations can be added without -modifying the core classes. - - -Utility classes -=============== - -TBD - -eca-logger.h - ECA_LOGGER -------------------------- - -Singleton class that provides an interface to Ecasound's logging -subsystem. Libecasound sends all log messages to this interface. -The actual logger implementation can be done in many ways. For example -in the console mode user-interface of Ecasound, TEXTDEBUG class -implements the ECA_LOGGER_INTERFACE class interface. It sends all -messages that have a suitable debug level to the console's standard -output. On the other hand, in qtecasound, ECA_LOGGER_INTERFACE is -implemented using a Qt widget. - -New ECA_LOGGER_INTERFACE implementations can be registered at -runtime with the ECA_LOGGER::attach_logger() member -function (declared in eca-logger.h). - - -Object maps -=========== - -Object maps are central repositories for commonly used objects. -Their main purpose is to add flexibility to handling different -object types - especially to handling dynamic addition and removal -of whole object types. They provide the following services: - -- listing all object types in any of the available - categories (for instance, list all effect types) - -- creating new object instances based on keyword strings - (for instance, returns an mp3 object if "foo.mp3" is given - as keyword) - -- adding new object types (object map item is identified by - tuple of "keyword, regex expression, object type") - -- removing object types - -- reverse mapping objects back to keyword strings - -In Ecasound, all access to object maps goes throuh the library-wide -ECA_OBJECT_FACTORY class, which provides a set of static functions -to access the object maps. - -This system may sound a bit complex, but in practise it is quite -simple and makes a lot of things more easier. For instance, when -adding new object types to the library, you only have to add one -function call which registers the new object; no need to modify any -other part of the library. It also makes it possible to add new -types at runtime, including dynamically loaded plugins. - -One special use-case is where an application linked against -libecasound adds its own custom object types on startup. All parts -of libecasound can use the custom objects, although they are not -part of library itself. - -All objects defined in libecasound are registered in the file -eca-static-object-maps.cpp. - -eca-object.h - ECA_OBJECT -------------------------- - -A virtual base class that represents an Ecasound object. All objects -handled by the object factory must inherit this class. - -eca-object-factory.h - ECA_OBJECT_FACTORY ------------------------------------------ - -The public interface to Ecasound's object maps. All its functions -are static. - -.. ################################################################# -.. ################################################################# - -Adding new features and components to Ecasound? -~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ - -Things to remember when writing new C++ classes -=============================================== - -TBD - -Copy constructor and assignment operator ----------------------------------------- - -Always take a moment to check your copy constructor and the assign -operation (=operation()). Basicly you have three alternatives: - -- Trust the automatically created default definitons. If you don't - have any pointers as data members, this isn't necessarily a bad - choice at all. At least the compiler remembers to copy all members! - -- If you have pointers to objects as class data members, you should - write definitions for both the copy-constructor and the assign - operation. - -- If you are lazy, just declare the two functions as null - functions, and put them in "private:"_ access scope. At least this way - nobody will use the functions by accident! - - -Audio objects -============= - -To implement a new audio object type, you must first select which -top-level class to derive from. Usually this is either AUDIO_IO -(the top-level class), AUDIO_IO_BUFFERED (a more low level interface) -or AUDIO_IO_DEVICE (real-time devices). - -The second step is to implement the various virtual functions declared -in the parent classes. These functions can be divided into four -categories: 1) attributes (describes the object and its capabilities), -2) configuration (routines used for setting up the object), 3) main -functionality (open, close, input, output, etc) and 4) runtime -information (status info). - -Adding the new object to Ecasound is much like adding a new effect -(see the next section). Basicly you just add it to the makefiles and -then register it to the appropriate object map (see below). - -Checklist for Audio Object Implementations ------------------------------------------- - -1. Check that read_buffer() and write_buffer() change the - internal position with either set_position_in_samples() - or change_position_in_samples() functions of ECA_AUDIO_POSITION. - Also, when writing a new file, extend_position() should - also be called. All this is done automatically if using - read_samples() and write_samples() from AUDIO_IO_BUFFERED. - -2. If implementing a proxy object, separately consider all public - functions of audioio-proxy.h (whether to reimplement or use - as they are). - -3. Check that open() and close() call AUDIO_IO::open() and - AUDIO_IO::close(), and in the right order. - -4. If the object supports seeking, seek_position() must - be implemented. - -5. Check that the set_parameter() and get_parameter() methods - work correctly when they are used for saving and restoring - audio object state (for example cs-edit EIAM command). - - -Effects and other chain operators -================================= - -Write a new class that inherits from CHAIN_OPERATOR or any of its -successors. Implement the necessary routines (init, set/get_parameter, -process and a default constructor) and add your source files to -libecasound's makefiles. Then all that's left to do is to add your -effect to libecasound/eca-static-object-maps.cpp, -register_default_objects(). Now the new effect can be used just -like any other Ecasound effect (parameters control, effect presets, etc). - -Another way to add effects to Ecasound is to write them as LADSPA -plugins. The API is well documented and there's plenty of -example code available. See http://www.ladspa.org -for more information. - - -Differences between audio objects and chain operators -===================================================== - -Design-wise, audio objects and effects (chain operators) aren't that -far away from each other. Many audio apps don't separate these -concepts at all (for instance most UG based synthesizers). In Ecasound -though, there are some differences: - -Input/output: - -- audio objects can be opened for reading writing or read\&write -- ... effects are not modal (i.e. modeless) -- audio objects read from, or write to, a buffer -- ... effects get a buffer which they operate on (in-place processing) - -Audio format: - -- audio objects have a distinct audio format (sample rate, bits, - channels) -- .... effects should be capable of accepting audio data in any format - (this is usually easy as Ecasound converts all input data to its - internal format) - -Control: - -- audio objects can be opened, closed, prepared, started and stopped -- ... effects have a much simpler running state: either uninitialized or ready-for-processing - -Position: - -- audio objects have length and position attributes -- ... effects just process buffers and don't need to care about position information - -A good example of the similarity between the two types are LADSPA -oscillator plugins. Although they are effects, you can easily use them -as audio sources (inputs) by specifying: - -:: - -"ecasound -i null -o /dev/dsp -el:sine_fcac,440,1" - - -LADSPA plugins -============== - -Ecasound supports LADSPA-effect plugins (Linux Audio Developer's Simple -Plugin API). See LAD mailing list web site for -more info about LADSPA. Other useful sites are -LADSPA home page and LADSPA documentation. - - -EIAM commands -============= - -Adding a new interactive mode commands requires changes to the -following files: - - -- libecasound/eca-iamode-parser_impl.h: Unique id for the new command - has to be added to enum Commands. - -- libecasound/eca-iamode-parser.cpp: The new command must be added - to the appropriate register_commands_*() function. - -- libecasound/eca-iamode-parser.cpp: The new command must be added - to the appropriate action_requires_*() sets. - -- libecasound/eca-control.cpp: The actual implementation of the - new command. - -- Documentation/ecasound-iam_manpage.yo: Documentation must be - added. - -.. ################################################################# -.. ################################################################# - -Application development using the Ecasound framework -~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ - -Console mode ecasound - [all languages] -======================================= - -This is the easiest way to take advantage of Ecasound features in your -own programs. You can fork ecasound, pipe commands to ecasound's -interactive mode or you can create chainsetup (.ecs) files and load -them to ecasound. You'll be able to do practically anything. The only -real problem is getting information from ecasound. You'll have to -parse ecasound's ascii output if you want to do this. To make this -a bit easier, Ecasound offers the wellformed output mode -and dump-* commands. These can be used to easily parse configuration and -status information. - - -Ecasound Control Interface - [C++, C, Python, Perl, ...] -======================================================== - -Idea behind Ecasound Control Interface (ECI) is to take a subset of -functionality provided by libecasound, write a simple API for it, and -port it to various languages. At the moment, at least C++, C and -Python implementations of the ECI API are available and part of the -main Ecasound distribution. ECI is heavily based on the Ecasound -Interactive Mode (EIAM), and the services it provides. - -Specific tasks ECI is aimed at: - -- 1. automating (scripting in its traditional sense) -- 2. frontends (generic / specialized) -- 3. sound services to other apps - - -NetECI - [various] -================== - -NetECI is a network version of the ECI API. When Ecasound is -started in server mode (see ecasound(1) for the related options), it -listens for incoming NetECI commands on a TCP socket. Client -applications can connect to this socket and use the connection to -control and observe the active session.

Additional implementations, -for example for Perl and PHP, are distributed independently. - -ECI is heavily based on Ecasound's interactive mode (EIAM), and the -services it provides.

What it does provide is an easy and generic way -to issue EIAM (Ecasound Inter-Active Mode) commands, access the -command return-values and perform error handling. - -This approach has two benefits. First, it is possible to keep the API -small, and thus make it easier to port ECI to new languages. Secondly, -it's possible to keep ECI relatively stable. Ecasound itself is a large, -developing library. New features are added all the time, and from time -to time, older parts of the library will get rewritten to better suit -new uses. Now for application developers wanting to take advantage of -libecasound, these constant changes are very annoying, especially if -your specific app doesn't need the latest new features. In these -cases, ECI is the best platform for application development. - - -% ---------------------------------------------------------------------- -\subsection{What's it good for?} - -Specific tasks ECI is aimed at: - -\begin{itemize} -\item 1. automating (scripting in its traditional sense) -\item 2. frontends (generic / specialized) -\item 3. sound services to other apps -\end{itemize} - - -% ---------------------------------------------------------------------- -\subsection{Services and behaviour} - -Here is a list of services provided by all ECI implementations: - -\subsubsection{Actions} -\begin{description} -\item[command(string)] -Issue an EIAM command. - -\item[command\_float\_arg(string, float)] -Issue an EIAM command. This function can be used instead of -\emph{command(string)}, if the command in question requires exactly one -numerical parameter. This way it's possible to avoid the extra -string -> float conversion, which would lead to lost precision. -\end{description} - -\subsubsection{Return values} -Each EIAM command has exactly one return value type. After a command -has been issued, only one last\_type() functions returns a non-empty -value. For example, last\_float() only returns a valid value if -\emph{last\_type() == 'f'} holds true. Not all EIAM commands return -a value (return type is void). - -\begin{description} -\item[last\_string()] -Returns the last string return value. - -\item[last\_string\_list()] -Returns the last collection of strings (one or more strings). - -\item[last\_float()] -Returns the last floating-point return value. Note! last\_float() -doesn't refer to the C/C++ type 'float'. In most implementations, -floats are 64bit values (doubles in C/C++). - -\item[last\_integer()] -Returns the last integer return value. This function is also -used to return boolean values, where non-zero means 'true' -and zero 'false'. - -\item[last\_long\_integer()] -Returns the last long integer return value. Long integers are -used to pass values like 'length\_in\_samples' and 'length\_in\_bytes'. -It's implementation specific whether there's any real difference -between integers and long integers. -\end{description} - -\subsubsection{Errors} -\begin{description} -\item[error()] -Returns true (!= 0) if error has occured during the execution -of last EIAM command. Otherwise returns false (= 0). - -\item[last\_error()] -Returns a string describing the last error. If the last EIAM command -was executed succesfully, last\_error() returns an empty string. - -\end{description} - -\subsubsection{Other} -\begin{description} -\item[initialize()] -Reserve resources. - -\item[cleanup()] -Free all reserved resources. -\end{description} - - - -% ---------------------------------------------------------------------- -\subsection{Porting to new environments} -Porting ECI to new languages should be easy. All there is to do is -to implement the services listed in the previous section to the target -language. In most cases it's to easiest to use the C++ or C ECI -as the underlying implementation to build upon. - - - -% ---------------------------------------------------------------------- -% ---------------------------------------------------------------------- -\section{Implementations} - - -% ---------------------------------------------------------------------- -\subsection{General} - -\subsubsection{Overview} -This section contains overview of how ECI is implemented in the -discussed language (eg. as a single class, set of classes, set of -routines, etc). - -\subsubsection{Usage} -A quick tutorial to get you started. - -\subsubsection{Example} -Implementation of the following: -\begin{enumerate} -\item Setup ECI to read audio from file, apply a 100Hz lowpass filter, and - send it to the soundcard (/dev/dsp). -\item Every second, check the current position. If the stream has - been running for over 15 seconds, exit immediately. Also, - every second, increase the lowpass filter's cutoff frequency - by 500Hz. -\item Stop the stream (if not already finished) and disconnect the - chainsetup. Print chain operator status info. -\end{enumerate} - - -% ---------------------------------------------------------------------- -\subsection{Notes Concerning Standalone ECI Implementations} - -The C implementation of ECI is not directly linked against the main -Ecasound libraries. Instead, the ecasound executable is launched -on the background and command pipes are used to communicate with it. - -The launched ecasound executable can be selected by using the -\emph{ECASOUND} environment variable. If it is not defined, -the C ECI implementation will try to launch ``ecasound'' (ie. -has to be somewhere in PATH). - -In addition to the C implementation, this also affects all -ECI implementations that are based on the C version. Currently -this includes at least the Perl, PHP and Python ECI modules. - -% ---------------------------------------------------------------------- -\subsection{C++} -\subsubsection{Overview} -C++ implementation is based around the ECA\_CONTROL\_INTERFACE class. -STL vector is used for representing collections of objects -(last\_string\_list()). - -\subsubsection{Usage} -\begin{enumerate} -\item \#include -\item create an instance of the ECA\_CONTROL\_INTERFACE class - and use its member functions -\item link you app agains libecasoundc (-lecasoundc) -\item compilation example: \emph{c++ -o ecidoc\_example ecidoc\_example.cpp `libecasoundc-config --cflags --libs`} -\end{enumerate} - -\subsubsection{Example} -\begin{verbatim} - -#include -#include -#include - -int main(int argc, char *argv[]) -{ - double cutoff_inc = 500.0; - - ECA_CONTROL_INTERFACE e; - e.command("cs-add play_chainsetup"); - e.command("c-add 1st_chain"); - e.command("ai-add some_file.wav"); - e.command("ao-add /dev/dsp"); - e.command("cop-add -efl:100"); - e.command("cop-select 1"); - e.command("copp-select 1"); - e.command("cs-connect"); - e.command("start"); - while(1) { - sleep(1); - e.command("engine-status"); - if (e.last_string() != "running") break; - e.command("get-position"); - double curpos = e.last_float(); - if (curpos > 15.0) break; - e.command("copp-get"); - double next_cutoff = cutoff_inc + e.last_float(); - e.command_float_arg("copp-set", next_cutoff); - } - - e.command("stop"); - e.command("cs-disconnect"); - e.command("cop-status"); - cerr << "Chain operator status: " << e.last_string() << endl; - - return(0); -} - -\end{verbatim} - -% ---------------------------------------------------------------------- -\subsection{C} -\subsubsection{Overview} -All C ECI functions are prefixed with "eci\_". When returning string -values, a const pointer to a null-terminated char array (const char*) -is returned. It's important to keep in mind that these are "borrowed" -references. If you need to later use the data, you must copy -it to application's own buffers. - -Returning a list of strings is implemented using two functions: -\emph{eci\_last\_string\_list\_count()} returns the number of strings -available, and \emph{eci\_last\_string\_list\_item(int n)} returns a -pointer (const char*) to the string at index \emph{n}. - -\emph{Note!} As of Ecasound 2.0.1, the C ECI implementation also - provides reentrant access to the ECI API. These - alternative routines are marked with '\_r' postfix. - -\subsubsection{Usage} - -\begin{enumerate} -\item \#include -\item use the eci\_* routines -\item link your app against libecasoundc (-lecasoundc) -\item compilation example: \emph{gcc -o ecidoc\_example ecidoc\_example.c `libecasoundc-config --cflags --libs`} -\end{enumerate} - -\subsubsection{Example} -\begin{verbatim} - -#include -#include -#include - -int main(int argc, char *argv[]) -{ - double cutoff_inc = 500.0; - - eci_init(); - eci_command("cs-add play_chainsetup"); - eci_command("c-add 1st_chain"); - eci_command("ai-add some_file.wav"); - eci_command("ao-add /dev/dsp"); - eci_command("cop-add -efl:100"); - eci_command("cop-select 1"); - eci_command("copp-select 1"); - eci_command("cs-connect"); - eci_command("start"); - - while(1) { - double curpos, next_cutoff; - - sleep(1); - eci_command("engine-status"); - if (strcmp(eci_last_string(), "running") != 0) break; - eci_command("get-position"); - curpos = eci_last_float(); - if (curpos > 15.0) break; - eci_command("copp-get"); - next_cutoff = cutoff_inc + eci_last_float(); - eci_command_float_arg("copp-set", next_cutoff); - } - - eci_command("stop"); - eci_command("cs-disconnect"); - eci_command("cop-status"); - printf("Chain operator status: %s", eci_last_string()); - eci_cleanup(); - - return(0); -} - -\end{verbatim} - -% ---------------------------------------------------------------------- -\subsection{Emacs} -\subsubsection{Overview} -The Ecasound package comes with an 'Ecasound' library for Emacs included. -ecasound.el is a implementation of the ECI API for Emacs, as well -as an interactive interface to Ecasound sessions implemented -on top of that. Simply use "M-x ecasound RET" to fire up an -interactive Ecasound session. - -All Emacs Lisp ECI functions are prefixed with ``eci\-''. -'ecasound.el' is implemented in a high level manner which means -that you won't find most of the commands known from libecasoundc like -last\_string, last\_float, etc. -Instead of that every call to function "eci-command", which accepts all -the well known IAM commands, returns ecasound's response in an appropriate type -automatically. -If an error occurs, e. g. there's a typo in a command or a file is not found, -the function returns ``nil''. In all other cases, either an automatically -converted Lisp value is returned, or ``t'' in the case where there was no -particular value returned. - -Additionally, most of the available IAM commands have their own Emacs Lisp -function including documentation and possibly a parameter list. All these -functions are interactive, so you can use them in ecasound-iam-mode simply -by invoking them via M-x or by pressing an assigned key combination. -Emacs will prompt you for the required parameters, providing completion -wherever possible. - -As a convention, "eci-command" and its variants do take a buffer or process -as an optional last argument. If this is ``nil'', the current -buffer is assumed to be the ecasound session refered to by this call. -This makes it possible to use several ECI sessions concurrently, dispatching -on the buffer or process in use. - -\subsubsection{Usage} -\begin{enumerate} -\item make ecasound.el available in your ``load-path'' -\item (require 'ecasound) -\item create a buffer with an associated Ecasound session (``eci-init'') -\item use ``eci\-'' functions with the new buffer -\end{enumerate} - -\subsubsection{Example} -\begin{verbatim} -(require 'ecasound) - -(defun example (file &optional cutoff-increment session) - (unless cutoff-increment (setq cutoff-increment 500.0)) - (with-current-buffer (or session (eci-init)) - (eci-cs-add "play_chainsetup") - (eci-c-add "1st_chain") - (eci-ai-add file) - (eci-ao-add "/dev/dsp") - (eci-cop-add "-efl:100") - (eci-cop-select 1) - (eci-copp-select 1) - (eci-cs-connect) - (eci-start) - (sit-for 1) - (while (and (string= (eci-engine-status) "running") - (<= (eci-get-position) 15)) - (eci-copp-set (+ cutoff-increment (eci-copp-get))) - (sit-for 1)) - (eci-command "stop") - (when (eci-cs-disconnect) - (destructuring-bind - ((cop n1 (copp n2 val))) - (cdr (assoc "1st_chain" (eci-cop-status))) - (message "%s %s is now %f" cop copp val))))) -\end{verbatim} - -NOTE: function ``eci-cop-status'' is actually a very high level function -which already converts the returned information to a nested list -structure. - -For more complex examples of the Emacs Lisp ECI implementation, see function -``eci-example'', ``ecasound-normalize'' and ``ecasound-signalview'' in -ecasound.el. - -% ---------------------------------------------------------------------- -\subsection{Python} -\subsubsection{Overview} -Python implementation is based around the ECA\_CONTROL\_INTERFACE class. -Lists are used for representing collections of objects. - -Note!

Try to run the ``ecasound'' - console user-interface and verify that the basic functionality - is working (ie. something like ``ecasound -i foo.wav -o - /dev/dsp''. - -\item If developing in C or C++, check that your application - is correcly linked: ``ldd /path/to/myapp''. All the libraries - should be properly found. - -\item Check error conditions. You should remember to check - for errors in your ECI apps using the eci\_error() and - eci\_last\_error() functions. Especially when intializing - ECI for the first time and after important commands - like ``cs-connect'', you should always check for errors. - -\item Use the ECASOUND\_LOGFILE environment variable to write all - engine output to a separate logfile. See ecasound(1) manpage - for details on how to use this mechanism. Requires Ecasound - version 2.4.5 or newer. - -\item Utilize the ``int-log-history'' ECI command added to - version 2.4.0 of Ecasound. Recent messages from the - engine can help to track down the problem. Before use, you - need to first set the history length to a non-zero value with - ``int-set-log-history-length''. - -\item Launch Ecasound in interactive mode (``ecasound -c''), - and issue the commands your ECI application is using, - manually one-by-one and see what happens. If something - goes wrong, increase Ecasound's debug level (for instance - ``-ddd'') and re-run the test. - -\end{enumerate} - -\end{document} diff --git a/library/ecasound/Documentation/users_guide/Makefile.am b/library/ecasound/Documentation/users_guide/Makefile.am deleted file mode 100644 index e0ed71a9e..000000000 --- a/library/ecasound/Documentation/users_guide/Makefile.am +++ /dev/null @@ -1,50 +0,0 @@ -# ---------------------------------------------------------------------- -# File: ecasound/Documentation/users_guide/Makefile.am -# Description: Ecasound documentation - user's guide -# License: GPL (see ecasound/{AUTHORS,COPYING}) -# ---------------------------------------------------------------------- - -# --------------------------------------------------------------------- -# Files going into distribution: - -EXTRA_DIST = users_guide.latex - -DISTCLEANFILES = \ - users_guide.log \ - users_guide.aux \ - users_guide.out \ - users_guide.dvi \ - users_guide.toc \ - users_guide.ps \ - ecasound_users_guide.pdf \ - html_uguide/users_guide.html \ - html_uguide/users_guide.haux \ - html_uguide/users_guide.htoc - -all: - -docs: ecasound_users_guide.pdf - -ecasound_eci_doc.pdf: eci_doc.latex eci_doc.dvi - -# note: to create the table of contents (which spans multiple pages), and -# re-calculate the page numbers after the page offset generated by table -# of contents, latex needs to be ran 3 times.

It can be used for simple tasks like audio playback, -recording and format conversions, as well as for multitrack effect -processing, mixing, recording and signal recycling. Ecasound supports -a wide range of audio inputs, outputs and effect algorithms. -Effects and audio objects can be combined in various ways, and their -parameters can be controlled by operator objects like oscillators -and MIDI-CCs. A versatile console mode user-interface is included in -the package. - -% ---------------------------------------------------------------------- -% ---------------------------------------------------------------------- -\chapter{Ecasound concepts} - -% ---------------------------------------------------------------------- -\section{Audio object} - -Audio objects are used to transfer audio from and to Ecasound. -Usually audio objects are either files (like wav, mp3 or ogg) -or devices (soundcard input/output). There are also some -special audio object types for transferring data between -applications. - -% ---------------------------------------------------------------------- -\section{Chain} - -Chain is the central signal flow abstraction. In many ways chains -are similar to audio cables. You have one input and one output -to which you can connect audio producers and consumers -(like guitar and amplifier for instance). - -But there are some differences. First it's possible to attach -chain operators (usually effects) to chains. This is somewhat like -replacing one cable with two, and putting an effect box between -them, but with chains it's just easier. A second important difference -is that chains can transport multiple channels of audio. It's possible -to attach mono, stereo or 24ch (or bigger) audio feeds to one -chain. Also all chain operators can handle these multichannel -streams. - -In addition to chain operators, chains also have separate -``mute'' and ``bypass'' functions. - -% ---------------------------------------------------------------------- -\section{Chain operators and controllers} - -Chain operators are used to process and analyze sample data. -They can be divided into gates, converters, signal analyzers and -to traditional effects like reverbs, delays and filters. - -It's also possible to attach special controller objects to chains. -These controllers are used to control chain operator parameters. -The typical examples are various oscillators and MIDI continous -controllers (knobs, sliders, etc found on MIDI-devices). - -Both types of objects are attached to chains. The term \emph{chain object} -refers to all objects that can be attached to chains - ie. -operators and controllers. - -% ---------------------------------------------------------------------- -\section{Chainsetup} - -Chainsetup is the central data object. All other objects (inputs, -outputs, chains, etc) are connected to some chainsetup. -Many chainsetups can exist at the same time (during one session), -but only one of them can be in use. In Ecasound documentation, -the term \emph{connected} is used to describe a chainsetup that -is in use. - -Another important chainsetup concept is that of a \emph{selected} -chainsetup. All editing operations are done on the currently selected -chainsetup. It is possible to have one chainsetup connected (currently -processing audio), while editing another, chainsetup that is selected -for editing. - -Loading and saving chainsetups is the primary mechanism -for storing and restoring state information. When saving -to files, the \emph{.ecs} file format is used. The file syntax -uses the same notation as Ecasound's console (and command-line) -interface. This makes it easy to edit the chainsetup files -outside Ecasound, either manually or using external utils. -See \href{http://eca.cx/ecasound/Documentation/ecasound_manpage.html}{ecasound(1)} -man page for details. - -% ---------------------------------------------------------------------- -\section{Current position} - -Information about current position is only stored for audio -objects and chainsetups. When you change chainsetup position, -all audio objects are affected. On the other hand, positions -of different audio objects can be changed independently. - -% ---------------------------------------------------------------------- -\section{Ecasound Control Interface - ECI} - -Ecasound Control Interface is an API for application -developers who want to take advantage of libecasound -in their own apps. See ``Ecasound Control Interface Guide'' -and ``Ecasound Programmer's Guide'' for more information. - -% ---------------------------------------------------------------------- -\section{Ecasound Interactive Mode - EIAM} - -Most of Ecasound's functionality is located in one -central library (libecasound). One thing that this library -provides is a simple interpreter, which can be used for -controlling Ecasound. This mode of operation is better -known as Ecasound's Interactive Mode (EIAM) - -The most common frontend for the Interactive Mode is the console-mode -Ecasound program. You can enter its Enteractive Mode -by issuing ``ecasound -c''. For more detailed information -the available commands, see \texttt{ecasound-iam(1)} man page. - -% ---------------------------------------------------------------------- -\section{Ecasound Option Syntax - EOS} - -One very notable feature of the console-mode ecasound -program is its command-line option syntax. You can -do pretty much everything from the command-line. - -But it doesn't end with the console mode ecasound. In -fact, interpreting these options is located in -the main libecasound library, and is very closely tied -to the interactive mode. - -As a result, the same syntax (tokens that look like -``-prefix:arg1,arg2,...,argN''), is used in various -parts of libecasound. Note that if any of the arguments -contain commas, those arguments need to be enclosed in -double-quotes (for example ``-prefix:"ar,g1",arg2''). - -Following is a partial list of the places where EOS syntax -has been used: - -\begin{itemize} -\item parsing command-line options -\item the interactive-mode (as arguments to the 'cs-option' command - [2.1dev4 and newer]) -\item saved chainsetup-files (.ecs format) -\item effect preset definitions (see for example - ``/usr/share/ecasound/effect\_presets'') -\item generic oscillator definitions (see for example - ``/usr/share/ecasound/generic\_oscillators'' -\end{itemize} - -% ---------------------------------------------------------------------- -% ---------------------------------------------------------------------- -\chapter{Using} - -% ---------------------------------------------------------------------- -\section{Where to start?} - -There's no one single right way to use Ecasound. You can use it as -a simple glue component for doing tasks that aren't handled by -other applications you are using, or because Ecasound does these tasks -more easily (or better even :)). But Ecasound can also serve as the -centre of your studio setup, doing everything from effects processing -to multitrack recording and mixing. - -This flexibility doesn't come for free. It's difficult to describe -Ecasound's features in a few phrases. Because of this, new users -are encouraged to start from the \texttt{Examples page} at -\url{http://www.eca.cx/ecasound/Documentation/examples.html}. -It isn't a perfect introduction, and definitely shows only one way to -use the software, but it does give an overall view of what can be done, -and more importantly, it shows that many tasks are actually quite simple -to do. - -% ---------------------------------------------------------------------- -\section{Rules for creating and modifying chainsetups} - -Here are a few rules that help writing valid chainsetups. -Whether you are editing chainsetup files (.ecs), some -graphical frontend, just using command-line options, etc; -these rules always apply: - -\begin{itemize} -\item Every chain has exactly \_one\_ input and \_one\_ output. -\item All inputs and outputs must be connected to some chain. -\item For every input/output, there is one and only one - definition (example: ``-i:file.wav''). -\item All routing from and to chains is based on selecting a set of - chains and then specifying an input or output (example: - ``-a:1,2 -i:file.ext''). -\item All audio copying and mixing is done channel-wise. If you attach - a 4-channel input and a two-channel output to a chain, that chain - will have 4 channels of audio, but only the first two channels - will be written to the output file. -\end{itemize} - -Note that these rules are checked only when \emph{connecting} the -chainsetup (when issuing commands such as ``cs-connect'', or ``start''). - -% ---------------------------------------------------------------------- -\section{Chain operators and controllers} - -The best place to start is to read through -the \href{http://eca.cx/ecasound/Documentation/ecasound_manpage.html}{ecasound(1)} -man page, which contains documentation for all native Ecasound -chain objects. - -% ---------------------------------------------------------------------- -\section{Configuration} - -User preferences are stored in \emph{\textasciitilde /.ecasound/ecasoundrc}. -See the \href{http://eca.cx/ecasound/Documentation/ecasoundrc\_manpage.html}{ecasoundrc(5)} -manual page for details. - -By default, files for effect presets and oscillator presets are -in \emph{/usr/share/ecasound}. - -% ---------------------------------------------------------------------- -\section{Common problems} - -\subsection{I get occasional audio dropouts during operation? How to get rid of them?} - -Check \url{http://www.oreillynet.com/pub/a/linux/2000/11/17/low_latency.html} -where you'll find a very good article written by Dave Phillips on -Linux low-latency issues. If you are in a hurry (or desperate :)), -here's a quick list of things to try: - -\begin{itemize} -\item Tune your disks (see the article) -\item Enable ecasound's double-buffering system by using the \emph{-z:db} - option [note! this is only necessary with Ecasound 2.0.x and older] -\item If you're still having problems, run ecasound as root (or with SUID-bit - set) and use ecasound's \emph{-r} option. This will raise ecasound's - scheduling priority to realtime (SCHED\_FIFO). [with ecasound 2.1 - and newer, just run ecasound as root and it will take care of - tuning the settings] -\item Try increasing ecasound's buffersize with the \emph{-b:sample\_frames} - option. Something like \emph{-b:4096} should do the trick. -\item If all else fails, try the various low-latency kernel patches - (again, check the article) -\end{itemize} - -There has been a lot of discussion about tuning your system for better -performance on linux-audio-dev and linux-audio-user mailing lists. You -can browse the list archives at \url{http://www.linuxdj.com/audio/lad/archive.php}. - -Here are links to selected messages from the ecasound-list archives: -\begin{itemize} -\item Tuning parameters for reliable recording \url{http://eca.cx/ecasound-list/2005/04/0038.html}. -\item Smart Buffering \url{http://eca.cx/ecasound-list/2001/10/0020.html}. -\item Ecasound for Recording \url{http://eca.cx/ecasound-list/2001/06/0016.html}. -\end{itemize} - -\subsection{Can I use multiple soundcards?} - -This is possible, but there are some issues you should be aware of. If -you try using multiple cheap soundcards to get more simultaneous -inputs for recording, it's likely that the resulting streams will not -be in sync. This problem is explained in detail in the Linux -Audio-Quality HOWTO section "Notes on Full Duplex Recording, and Other -Realtime Issues": \url{http://karmak.org/archive/2003/02/audio_quality_HOWTO.htm}. -The original page at \url{http://www.linuxdj.com/audio/quality/} is no -longer available. - -\subsection{Problems with panning mono files} - -In situations where you need to convert mono -audio objects to multichannel objects, Ecasound -can behave in a somewhat unexpected manner. - -For instance, the correct way to set panning for -three individual mono input files, and mix the -resulting stereo output to soundcard, is: - -\begin{verbatim} -ecasound -a:1 -i:monofile1.wav -erc:1,2 -epp:0 \ - -a:2 -i:monofile2.wav -erc:1,2 -epp:50 \ - -a:3 -i:monofile3.wav -erc:1,2 -epp:100 \ - -a:all -f:16,2,44100 -o:alsa -\end{verbatim} - -The actual signal chain is something like: - -\begin{verbatim} -monofile1.wav |--'1'---- erc ----| epp |---\ - \-----| |---\\ - \\ -monofile2.wav |--'2'---- erc ----| epp |------- | alsa - \-----| |------- | - // -monofile3.wav |--'3'---- erc ----| epp |---// - \-----| |---/ - -('---' = mono channel) -\end{verbatim} - -The critical points to notice are: - -\begin{itemize} -\item ecasound automatically notices that the three - input files are mono files so chains are initialized - with one mono input -\item chains contain mono signal until -erc operator, - which transforms the chain into a stereo chain - by copying the data from ch1 to ch2 -\item now -epp works as expected (sets the stereo balance - for one input) -\item chains are mixed to the soundcard device channel-wise -\end{itemize} - -If you leave out the -erc operators, chains will still be converted -to stereo (as -epp is a stereo operator), but on each chain, only -the first channel (left) will contain any audio from the input -files. - -\subsection{Filenames with commas not handled correctly} - -There are some pitfalls in how commas in filenames are handled -by ecasound. If you have a filename ``foo,bar.ogg'', the following -will not work: - -\begin{verbatim} -ecasound -i foo,bar.ogg -o alsa -\end{verbatim} - -The only way around this is to escape all the commas with backslashes: - -\begin{verbatim} -ecasound -i foo\\,bar.ogg -o alsa -\end{verbatim} - -The backslash has to be a double-backslash as the shell strips -one of the backslashes away before passing the string to ecasound. - -% ---------------------------------------------------------------------- -% ---------------------------------------------------------------------- -\chapter{User interfaces and Applications} - -For a complete list of user-interfaces and applications built -on top of Ecasound, visit Ecasound's web site at \url{http://www.eca.cx}. - -% ---------------------------------------------------------------------- -\section{Ecasound} - -The standalone program ``ecasound'' is the primary user interface -for Ecasound. - -See \href{http://eca.cx/ecasound/Documentation/ecasound_manpage.html}{ecasound(1)} -man page and the \texttt{Examples web page} -at \url{http://www.eca.cx/ecasound/Documentation/examples.html}. - -% ---------------------------------------------------------------------- -\section{Ecasignalview} - -Ecasignalview is an utility program for monitoring signal amplitude -and peak statistics. It's primarily used when adjusting -signal levels for recording. - -\subsection{Basic use} - -The basic use scenario is to record audio from a soundcard device, -visualize it with vu-meters and write it to a null output. - -\begin{verbatim} -# OSS-drivers (or properly installed ALSA OSS-emulation) -ecasignalview /dev/dsp null - -# native ALSA-mode, recording from the 'default' device -ecasignalview alsa,default null -\end{verbatim} - -It is possible to reset the max-peak and clipped-samples -counters by sending a SIGHUP signal to the process (i.e. -from another console: "killall -v -HUP ecasignalview"). - -To monitor the input signal you can either use the soundcard's -analog (or in some cases, digital) monitoring functions by -enabling line/mic-in monitoring using \emph{alsamixer} (ALSA), -\emph{aumix} (OSS) or some other mixer application. Another option is to -use ecasignalview to do the monitoring. In this case the correct -command is: - -\begin{verbatim} -# OSS input and output -ecasignalview /dev/dsp /dev/dsp - -# corresponding ALSA command -ecasignalview alsa,default alsa,default -\end{verbatim} - -Ecasignalview command-line options allow you to fine-tune -the way monitoring is done: - -\begin{verbatim} -# increased refresh rate 20Hz -ecasignalview -r:50 alsa null - -# larger buffersize (1024 samples) -ecasignalview -b:1024 alsa null - -# recording in mode 32bit/10channels/96000Hz with -# interleaved channels -ecasignalview -f:s32,10,96000,i alsa null -\end{verbatim} - -It can also be used with files and real-time devices like -JACK inputs and outputs: -\begin{verbatim} -# monitor audio recorded by JACK system input (first 2ch) -ecasignalview -f:f32,2 jack,system null - -# monitor audio from JACK application ``foosynth'' -ecasignalview -f:f32,2 jack,foosynth null - -# play and monitor a file input -ecasignalview foo.wav alsa -\end{verbatim} - -\subsection{Further Reading} - -See \texttt{ecatools(1)} man page for a detailed listing of -available command-line options. - -% ---------------------------------------------------------------------- -\section{Ecatools} -See \texttt{ecatools(1)} man page. - -% ---------------------------------------------------------------------- -% ---------------------------------------------------------------------- -\chapter{Advanced features} - -% ---------------------------------------------------------------------- -\section{Audio loop devices} - -Just by using normal chain connections it's not possible to -route audio from one Ecasound chain to another. One way -around this limitation is loop devices. They were introduced -in Ecasound 1.7.0. - -\subsection{Example of use} - -An example use-case where we route audio from chains ``1'' and ``2'' -to chain ``3'' which is amplified and send to a soundcard output (``alsa''). - -\begin{verbatim} ---cut-- -# note, the second loop parameter is the loop id-number; -# it is used to associate loop inputs with correct loop outputs -ecasound -a:1 -i:some.mp3 - -a:2 -i:another.mp3 - -a:1,2 -o:loop,1 - -a:3 -ea:200 -i:loop,1 -o alsa ---cut-- - -\end{verbatim} - -Both inputs are eventually routed to chain "3", where a -ea:200 is -applied to the signal. This does have one downside, loop device -adds latency (-b:x -> latency of x frames). - -% ---------------------------------------------------------------------- -\section{Ecasound Wave Files - the EWF (.ewf) format} - -\subsection{General} - -Ecasound Wave File (.ewf) is a simple wrapper format for controlling -other audio objects. Ewf files are useful for offsetting or time-shifting -audio files (for instance play a short audio clip in the middle of -a long multitrack mix), for minimizing diskspace usage during -multitrack recording (output offsetting ) and looping. - -Starting from Ecasound version 2.5.0, similar functionality is -provided by special purpose audio object types 'audioloop', 'audioselect' -and others. You may choose between EWF and these audio object types -based on your specific needs. See -\href{http://eca.cx/ecasound/Documentation/ecasound_manpage.html}{ecasound(1)} -man page and the \texttt{Examples web page} -at \url{http://www.eca.cx/ecasound/Documentation/examples.html} -for many examples of using these. - -Writing to EWF file is nowadays considered to be a deprecated -feature and it may be removed in a future release. - -\subsection{File format} - -Ewf-files are stored in ascii format. The syntax is based on ``key=value'' -pairs. The same syntax is used with Ecasound resource files. See -\href{http://eca.cx/ecasound/Documentation/ecasoundrc\_manpage.html}{ecasoundrc(5)} -man page for detailed info. Currently recognized ewf keywords are: - -\begin{itemize} -\item source - audio object name (string) {[}read,write{]} -\item offset - insert audio object at offset (time) {[}read,write{]} -\item start-position - start offset inside audio object (time) {[}read{]} -\item length - how much of audio object data is used (time) {[}read{]} -\item looping - whether to loop sample data (true or false) {[}read{]} -\end{itemize} - -All time values are interpreted as seconds (need not be an integer -but can be given as a decimal number, e.g. ``1.05''). However if -the value is an integer number and has a postfix of ``sa'' (e.g. -``44100sa''), it is interpreted as time expressed as samples (in -case of a multichannel stream, time in sample frames). - -\subsection{Example of ewf use} - -Let's look at a simple example .ewf file: - -\begin{verbatim} --- test.ewf -- -source = test.wav -offset = 5.0 -start-position = 2.0 -length = 3.0 -looping = true ---cut-- -\end{verbatim} - -Now what happens when you issue "ecasound -i test.ewf -o alsa"? -Because of the ``offset'' definition, the first 5 seconds will be -silent. After that ecasound will start to read data from ``test.wav''. -But as ``start-position'' is not zero, ecasound will skip the -first 2 seconds. After 8 seconds has passed (``offset'' + -``length''), ecasound will loop back to ``start-position''. -This looping will continue until the user interrupts the operation. - -% ---------------------------------------------------------------------- -\section{Effect presets} - -\subsection{General} -Ecasound has a powerful effect preset system that allows you to create -new effects by combining basic effects and controllers. - -Presets can be stored into separate files or they can be stored -into a global database. Either way, the preset format is the same -(also see \href{http://eca.cx/ecasound/Documentation/ecasoundrc\_manpage.html}{ecasoundrc(5)} - man page, the same file format and syntax is used): - -\begin{verbatim} -preset_name = effects controllers | ... | effects controllers -\end{verbatim} - -Effects and controllers are specified using the EOS syntax, -the same syntax that is used for parsing command-line options -(``-ea:100'', ``-kl:1,0,100,5'', etc). The pipe character is -used to separate parallel chains. - -Just like in shell scripts, the '$\backslash$' character can -be used to spread definitions across multiple lines. - -\subsection{Example of preset use} -Ecasound effect presets are in fact small Ecasound engines that -behave just like native effects. Here's an example of a -multi-chain effect preset: - -\begin{verbatim} ---cut file 'bassbooster.ecp'-- -# let's put the low freqs into one chain and high freqs in another -bassbooster = -efl:2000 -ea:200 | -efh:2000 -ea:50 -# note, the '|' sign separates parallel chains ---cut-- -\end{verbatim} - -Once defined, you can use the preset in the following way: - -\begin{verbatim} ---cut-- -ecasound -a:1 -i:some.mp3 -pf:bassbooster.ecp - -a:2 -i:another.mp3 -pf:bassbooster.ecp - -a:1,2 -o:alsa ---cut-- - \end{verbatim} - -When separate files are used (the ``-pf:name'' option), -Ecasound always loads the first preset it finds. If the -file contains more presets (additional ``key=value'' -pairs), -they are ignored. - -An alternative way to define presets is to put the -definition in the global preset list (usually in -``/usr/local/share/ecasound/effect\_presets''. Once you've -added a line defining ``bassbooster'', you can use it -like: - -\begin{verbatim} ---cut-- -ecasound -a:1 -i:some.mp3 -pn:bassbooster - -a:2 -i:another.mp3 -pn:bassbooster - -a:1,2 -o:alsa ---cut-- -\end{verbatim} - -\subsection{Preset parameters} - -Parameters of operators belonging to a preset can be -exposed as preset paramters. Example: - -\begin{verbatim} ---cut preset definition-- -f_res_lowpass = -ef3:%1,1.5,0.7 ---cut-- -\end{verbatim} - -In the above example, the lowpass filter cutoff is exposed -as a parameter of the ``f\_res\_lowpass'' preset. The preset -can be used just like any other Ecasound operator. The -following two commands will results in identical output: - -\begin{verbatim} ---cut-- -ecasound -i:foo.mp3 -o:alsa -pn:f_res_lowpass,800 -ecasound -i:foo.mp3 -o:alsa -ef3:800,1.5,0.7 ---cut-- -\end{verbatim} - -\subsection{Parameter descriptors} - -Ecasound preset parameters can be described using the following -set of descriptors: - -\begin{verbatim} - -pd:name_of_preset = preset description - -ppn:par1,...,parN = parameter names (public params) - -ppd:val1,...,valN = default param values - -ppl:val1,...,valN = lower bounds for param values - -ppu:val1,...,valN = upper bounds for param values - -ppt:flags1,...,flagsN = special flags for param N - ('i'=integer, 'l'=logarithmic, 'o'=output, 't'=toggle) -\end{verbatim} - -The option can only be used inside preset definitions (in ``effect\_presets'' -files, or individual ``*.ecp'' files). An example preset parameter -definition: - -\begin{verbatim} ---cut-- -f_two_filters = -efl:800 -ea:%1 | -efh:800 -ea:%2 \ - -pd:Parallel_highpass_and_lowpass_filters \ - -ppl:0,0 -ppu:1000,- \ - -ppd:100,100 -ppn:lowgain,highgain ---cut-- -\end{verbatim} - -The above preset ``f\_two\_filters'' has two parameters, which -are described using the ``-pd'' descriptor. Recommended lower and -upper bounds for the parameters are defined with ``-ppl'' and -``-ppu'' descriptors. Default values for the parameters are -specified with ``-ppd''. - -% ---------------------------------------------------------------------- -\section{Gate operators} - -Gates are just like any other chain operators. They are assigned to -a chain, and process passing audio data buffers. One special feature -of gates is the ability to crop sections of audio files, for instance -to achieve automatic volume-based cutting of audio streams: - -\subsection{Example of use} - -The following sequence cuts the section {[}60:00 sec -> -61:00 sec{]} from ``guitar.wav'' into ``gate-test.wav'': - -\begin{verbatim} ---cut-- -|\$ ls -la guitar.wav --rw-rw-r-- 1 kaiv kaiv 15790124 Sep 30 23:27 guitar.wav - -|\$ ecasound -i guitar.wav -o gate-test.wav -gc:60,1 - -|\$ ls -la gate-test.wav --rw-rw-r-- 1 kaiv kaiv 180268 Dec 12 22:13 gate-test.wav ---cut-- -\end{verbatim} - -The threshold gate is used similarly: - -\begin{verbatim} ---cut-- -|\$ ecasound -i gate-test.wav -o gate-test-rms.wav -ge:11.2,5,1 - -|\$ ecasound -i gate-test.wav -o gate-test-peak.wav -ge:5,5,0 - -|\$ ls -la gate*wav --rw-rw-r-- 1 kaiv kaiv 163884 Dec 12 22:18 gate-test-peak.wav --rw-rw-r-- 1 kaiv kaiv 143404 Dec 12 22:17 gate-test-rms.wav --rw-rw-r-- 1 kaiv kaiv 180268 Dec 12 22:13 gate-test.wav ---cut-- - \end{verbatim} - -In the first case, the gate is opened when the RMS-volume goes over the ``11.2\%'' -threshold, and closed when RMS-volume falls below ``5\%''. In the second, -case, both entry and close thresholds are ``5\%'' (peak volume). - -% ---------------------------------------------------------------------- -\section{LADSPA plugins} - -Ecasound supports LADSPA-effect plugins (Linux Audio Developer's -Simple Plugin API). See \href{http://eca.cx/ecasound/Documentation/ecasound_manpage.html}{ecasound(1)} -man page and the LADSPA web site at ``www.ladspa.org'' for more information. - -\subsection{Ecasound is not able to find any LADSPA plugins I have installed!} - -Just installing the LADSPA SDK - ``www.ladspa.org'' -- should be enough. The plugins themselves are stored in shared library -files (.so). They are usually stored in ``/usr/local/lib/ladspa''. To test -whether Ecasound finds the plugins, issue: - -echo "ladspa-register" | ecasound -c - -You should get a list of all installed LADSPA plugins. If this doesn't -work, you need to make sure Ecasound is compiled with LADSPA enabled (ie. -ladspa.h header was present when Ecasound was compiled). The precompiled -rpm-binaries have this, but if you've compiled Ecasound yourself you -should recompile after installing the LADSPA SDK. - -Also, check Dave Phillips' great -article on Oreillynet - -\url{http://www.oreillynet.com/pub/a/linux/2001/02/02/ladspa.html}. - -% ---------------------------------------------------------------------- -\section{JACK Audio Server} -\label{JACK Audio Server} - -JACK is system for handling real-time, low latency audio. -It allows multiple independent applications to access the system -audio hardware and also to route audio between applications. - -JACK is different from other audio server efforts in that it has been -designed from the ground up to be suitable for professional audio -work. This means that it focuses on two key areas: synchronous -execution of all clients, and low latency operation. - -Note that Ecasound must be compiled with JACK support enabled -(the ``--with-jack'' configure option) to take advantage of -the functionality described in this section. - -\subsection{Basic Input and Output} - -Let's start with how to play a file using Ecasound and JACK: - -\begin{verbatim} -ecasound -i foo.wav -o jack,system -\end{verbatim} - -This will create a separate JACK output port for each channel -of ``foo.wav'', and automatically connect these Ecasound ports to -the JACK system PCM output ports. - -Note that ecasound does not allow to mix objects with different -sampling rates (without explicitly inserting ``samplerate'' -conversion objects). That means that if sampling rate of ``foo.wav'' -does not match the current JACK system rate, the above command -wil fail. - -The connections creadted are as follows: - -\begin{verbatim} -ecasound:out_1 --> system:playback_1 -ecasound:out_2 --> system:playback_2 -\end{verbatim} - -If ``foo.wav'' was a four channel file, the same command would -connect all channels: - -\begin{verbatim} -ecasound:out_1 --> system:playback_1 -ecasound:out_2 --> system:playback_2 -ecasound:out_3 --> system:playback_3 -ecasound:out_4 --> system:playback_4 -\end{verbatim} - -To record a file, you'd issue: - -\begin{verbatim} -ecasound -f:,2 -i jack,system -o foo.wav -ecasound -f:f32,2,44100 -i jack,system -o foo.wav -\end{verbatim} - -Here we use ``-f:bits,channels,srate'' to set how many channels -to record from the sound device using JACK. As described in -the \href{http://eca.cx/ecasound/Documentation/ecasound_manpage.html}{ecasound(1)} -man page, the parameters to ``-f'' may be overridden -by the audio objects. In case of JACK, the server always sets -the sampling rate, and also the sample format is fixed to 32bit -floats. Because of this, the above two examples achieve the same -result (but you may find the latter command more readable). - -It is possible to add another ``-f'' before ``-o foo.wav'' -if you want to write the file in a different format. For -example to convert the sample format to 16bit fixed: - -\begin{verbatim} -ecasound -f:f32,2 -i jack,system -f:s16,2 -o foo.wav -\end{verbatim} - -\subsection{More Advanced Port Creation} - -Ecasound also offers the following alternative ways -to create input and output ports: - -\begin{verbatim} -ecasound -i foo.wav -o jack -ecasound -i foo.wav -o jack,remote_client -ecasound -i foo.wav -o jack,remote_client,local_portprefix -ecasound -i foo.wav -o jack,,local_portprefix -ecasound -i foo.wav -o jack_multi,remote_client:port_1,system:port_2 -ecasound -i jack -o foo.wav -ecasound -i jack,remote_client -o foo.wav -ecasound -i jack,local_portprefix -o foo.wav -\end{verbatim} - -See \href{http://eca.cx/ecasound/Documentation/ecasound_manpage.html}{ecasound(1)} -manual page for descriptions of the ``jack\_multi'' audio object and the variants -of ``jack'' usage. - -\subsection{Transport Control} - -Transport controls are functions like ``start'', ``stop'', ``seek'', -etc, that are commonly available in audio applications that -maintain some kind of current position. JACK's transport -control interface allows controlling the transport state -of all the apps connected to one JACK server from a single -application. Ecasound can support this functionality in -four different modes (``notransport'', ``send'', ``recv'' -and ``sendrecv''). - -By default Ecasound will both send and reveive transport -events (position and state) to other JACK clients -(mode ``sendrecv''): - -\begin{verbatim} -ecasound -c -i null -o jack -\end{verbatim} - -To use transport control in Ecasound, you have to have at least -one published input or output JACK port. Here we publish -one null output port. After giving the initial ``engine-launch'' command -in Ecasound interactive mode, you are now able to use -further EIAM commands to control all other JACK apps connected -to the same server. Commands like -``stop'', ``setpos 20'', ``rw 10'', ``fw 10'', and so should -affect other apps. - -By default, Ecasound doesn't react to outside transport -control. To enable this: - -\begin{verbatim} -ecasound -c -i foo.wav -o jack,system -G:jack,eca_slave,recv -\end{verbatim} - -After giving an initial ``engine-launch'' to Ecasound, you should -now be able to use other JACK apps to control Ecasound's -playback of ``foo.wav''. - -To combine external control with the ability to control -the transport from ecasound's user-interface: - -\begin{verbatim} -ecasound -c -i foo.wav -o jack,system -G:jack,eca_slave,sendrecv -\end{verbatim} - -\subsection{JACK and Ecasound states} - -To have a good understanding of the overall system, it's important -to understand how Ecasound and JACK states relate to each other. - -When an Ecasound chainsetup is connected (EIAM-command ``cs-connect''), -a connection is established with the JACK server, and all the -JACK ports in that chainsetup are registered to it. -Once Ecasound's engine is launched with EIAM-command ``engine-launch'', -connections (if any are specified) are made to the ports of other -JACK clients. In this state Ecasound is ready to process -incoming transport state and position changes. - -When Ecasound processing is started (either with ``start'' or -by an incoming transport event), Ecasound's engine runs -as a node in the JACK system. When processing is stopped (either -with ``stop'', or by a transport event), Ecasound's engine is -not run. - -Any connections (initiated by Ecasound) to other clients, -are disconnected once ``engine-halt'' is issued and engine -operation is stopped. Connection to the remote JACK server -as well as unregistering any ports is performed when chainsetup -is disconnected (``cs-disconnect''). - -Note! Normally you don't need to go through all the steps one -by one. Instead issuing ``start'' will automatically connect -the chainsetup and launch the engine. Similarly ``cs-disconnect'' -will stop processing and halt the engine if needed. - -\subsection{Troubleshooting} - -Ecasound v2.2 and earlier don't have the capability to change -the engine buffersize and sampling rate dynamically during -processing. As a consequence, running Ecasound will fail if -the currrent values for these parameters do not match -the ones used by the JACK server. In other words, you have -to correctly set the buffersize (with ``-b:xxx'') and sampling -rate (with ``-f:bits,channels,srate'' and possibly using the -\emph{resample} audio object). This is the first thing to -check if communication with JACK does not work. - -Future versions of Ecasound will hopefully solve this -problem. This issue is covered by Ecasound development item -``edi-31 - Support for dynamic sampling rate and buffersize changes.''. - -\subsection{Deprecated JACK input/output syntax} -Ecasound 2.5 and older supported ``jack\_alsa'', ``jack\_auto'' -and ``jack\_generic'' object types, but these are now replaced -by a more generic ``jack'' interface. The old variants this -work, but are now considered deprecated (they work but may be -removed in a future Ecasound release). - -% ---------------------------------------------------------------------- -% ---------------------------------------------------------------------- -\chapter{Miscellaneous} - -% ---------------------------------------------------------------------- -\section{Security Considerations} - -When given the -r option (raise priority), Ecasound tries to raise -its scheduling priority (to so called SCHED\_FIFO realtime scheduling) -and to avoid swapping, locks all its memory. To do this, -root-privileges are required. So either Ecasound has to be run as -root (logged in as root, or using the 'sudo' program), it has to be -installed with the suid-root bit set, or otherwise be granted necessary -privileges to turn on real-time schedule (see below). Now is this a safe -thing to do? - -Although there are no known vulnerabilities, setting Ecasound suid-root is -not safe. Whether this is a real problem depends on the particular setup -(whether connected to a network or not, any untrusted users with shell -access, ...). - -The basic problem is that Ecasound (or at least 2.0 and earlier) -doesn't contain any code for altering privilege levels. If it is run -with root-privileges, it does everything as root - including forking -external programs such as mp3 and ogg utilities and editors. - -But all in all, this shouldn't be that big of an issue for many users. For -noncritical uses, just don't set the suid-bit, but run as a normal user. If -you have an untrusted setup, and you don't want to login as root, but still -need to run in raised-priority mode, the following can help to limit -the risk of suid-root use: - -\begin{verbatim} - cd /usr/local/bin - chown root.ecausers ecasound - chmod 4750 ecasound -\end{verbatim} - -In other words, the ecasound binary is set as suid-root (so it is run with -root-privileges), but only root and members of the 'ecausers' group can -start it. You of course first have to create the 'ecausers' group to your -system. - -The ideal solution would be that ecasound would not need full root-privileges, but -privileges for changing scheduling and locking memory. On recent Linux systems, -there are couple ways to achieve this. - -The Realtime Linux Security Module (LSM) is one practical solution -(see \url{http://sourceforge.net/projects/realtime-lsm/} and -\url{http://lwn.net/Articles/106009/}). This module is a loadable extension for -Linux 2.6 kernels. It selectively grants realtime permissions to specific user groups -or applications. Unfortunately Realtime LSM does not yet come with the standard Linux -kernel, so you need to install it separately. - -A more recent approach, and one that might be adopted by popular GNU/Linux distributions, -is the \emph{rtprio} extension to Linux resource limits. See -\href{http://lwn.net/Articles/134460/} for a good overview of this approach and how -it compared to the LSM mechanism described above. - -\end{document} diff --git a/library/ecasound/INSTALL b/library/ecasound/INSTALL deleted file mode 100644 index 8520c274c..000000000 --- a/library/ecasound/INSTALL +++ /dev/null @@ -1,279 +0,0 @@ -======================================================================= -*** Ecasound - INSTALL *** -======================================================================= - - The `configure' shell script attempts to guess correct values for -various system-dependent variables used during compilation. It uses -those values to create a `Makefile' in each directory of the package. -It also creates the file `config.h' in the top-level source directory. -This file contains system-dependent definitions. Finally, it creates -a shell script `config.status' that you can run in the future to -recreate the current configuration, a file `config.cache' that saves -the results of its tests to speed up reconfiguring, and a file -`config.log' containing compiler output (useful mainly for debugging -`configure'). - - If you need to do unusual things to compile the package, please try -to figure out how `configure' could check whether to do them, and mail -diffs or instructions to the address given in the `README' so they can -be considered for the next release. If at some point `config.cache' -contains results you don't want to keep, you may remove or edit it. - - The file `configure.in' is used to create `configure' by a program -called `autoconf'. You only need `configure.in' if you want to change -it or regenerate `configure' using a newer version of `autoconf'. - -The simplest way to compile this package is: - - 1. `cd' to the directory containing the package's source code and type - `./configure' to configure the package for your system. If you're - using `csh' on an old version of System V, you might need to type - `sh ./configure' instead to prevent `csh' from trying to execute - `configure' itself. - - Running `configure' takes awhile. While running, it prints some - messages telling which features it is checking for. - - 2. Type `make' to compile the package. - - 3. Type `make install' to install the programs and any data files and - documentation. - - 4. If you have not specified an alternative install prefix with --prefix - option, make sure that you have `/usr/local/lib´ in your - `/etc/ld.so.conf' and then run `/sbin/ldconfig´ (as root). - - 5. You can remove the program binaries and object files from the - source code directory by typing `make clean'. To also remove the - files that `configure' created (so you can compile the package for - a different kind of computer), type `make distclean'. There is - also a `make maintainer-clean' target, but that is intended mainly - for the package's developers. If you use it, you may have to get - all sorts of other programs in order to regenerate files that came - with the distribution. - -Ecasound specific options -========================= - -`--enable-all-static' - Build static binaries that are not linked against any - shared libraries.

Defaults to yes if Ruby interpreter - is found on the system. - -`--with-extra-cppflags=ARG´ - Pass extra options to preprocessor (cpp). This option should - be used to add non-standard header paths to the search path. - -`--with-extra-libs=ARG´ - Pass extra options to linked (ld). This option should - be used to add non-standard library paths to the search - path, as well as additional libraries to link against. - -Supported automake/autoconf features -==================================== - -Ecasound uses the autotools (automake, automake and libtool) -build system framework. Standard practises (see below for -references) are followed where applicable. - -Some features offered by the autotools do not work without -explicit support from the package. Following is a short list of -features that Ecasound _does_ support. If you encounter any -problems in using these features with Ecasound, please report -them as bugs. - -1. Building Ecasound in a directory separate from the source - directory. - Example: "mkdir objdir ; cd objdir ; ../configure ; make" - -2. 'uninstall' make target - You should be able to uninstall Ecasound by running "make uninstall". - Note that if you override any make variable when running "make install", - you should specify the same variables also when running "make uninstall". - Reference: Automake manual (see below) - -3. 'DESTDIR' make variable for staging installs - Reference: http://sources.redhat.com/automake/automake.html#Install - -4. 'prefix', 'datadir', pkgdatadir' make variables - You should be able to override any of the make variables - on the make command-line. But remember to always override - the same variables when you switch between make targets (see - notes on (2)). - Example: make prefix=/tmp/ecasound-foobar install - -5. Overriding CPPFLAGS, CFLAGS, CXXFLAGS, etc variables. - It is possible to override these parameters both before - running the configure script (specify new values as - environment variables), or at make time (specify new - values on the make command-line). Note that these - mechanisms are exclusive to each other. - - To specify extra preprocessing and compile flags that are - applied when building libecasound components, but not when - building the test programs run by 'configure' script, one can - use the environment variables ECA_S_EXTRA_CPPFLAGS and - ECA_S_EXTRA_CFLAGS (define before running 'configure'). - -General references: - -o Automake manual - http://sources.redhat.com/automake/automake.html - -o Autoconf manual - http://www.gnu.org/software/autoconf/manual/ - -o GNU Coding Standards - http://www.gnu.org/prep/standards/ - - -Specifying the System Type -========================== - - There may be some features `configure' can not figure out -automatically, but needs to determine by the type of host the package -will run on. Usually `configure' can figure that out, but if it prints -a message saying it can not guess the host type, give it the -`--host=TYPE' option. TYPE can either be a short name for the system -type, such as `sun4', or a canonical name with three fields: - CPU-COMPANY-SYSTEM - -See the file `config.sub' for the possible values of each field. If -`config.sub' isn't included in this package, then this package doesn't -need to know the host type. - - If you are building compiler tools for cross-compiling, you can also -use the `--target=TYPE' option to select the type of system they will -produce code for and the `--build=TYPE' option to select the type of -system on which you are compiling the package. - -Operation Controls -================== - - `configure' recognizes the following options to control how it -operates. - -`--cache-file=FILE' - Use and save the results of the tests in FILE instead of - `./config.cache'. Set FILE to `/dev/null' to disable caching, for - debugging `configure'. - -`--help' - Print a summary of the options to `configure', and exit. - -`--quiet' -`--silent' -`-q' - Do not print messages saying which checks are being made. To - suppress all normal output, redirect it to `/dev/null' (any error - messages will still be shown). - -`--srcdir=DIR' - Look for the package's source code in directory DIR. Usually - `configure' can determine that directory automatically. - -`--version' - Print the version of Autoconf used to generate the `configure' - script, and exit. - -`configure' also accepts some other, not widely useful, options. diff --git a/library/ecasound/Makefile.am b/library/ecasound/Makefile.am deleted file mode 100644 index f413cc2d1..000000000 --- a/library/ecasound/Makefile.am +++

see entry below - about signal handling changes and ecasound(1) for - more details - - added: -eadb chainop, like -ea/-eac, but gain given in dB; - documented in ecasound(1) - - added: -chorder chainop; see ecasound(1) - - added: optional inner loop optimizations using liboil; - enable with '--enable-liboil' - - added: OSC support added, see ecasound(1) and - Documentation/ecasound_osc_interface.txt; sffeat:2541462 - - added: in ncurses mode, honor COLUMNS environment variable - - added: configure - added '--with-extra-cppflags' and - '--with-extra-libs' options - - added: new 'cop-get' command; see ecasound-iam(1) [alinson] - - changed: ecasound now defines "-D_XOPEN_SOURCE=500" for - all builds, expressing that the codebase expects - the build environment be compatible with the Single - UNIX Spec v2 (1998); thanks to Jussi Laako for - reminding about this - - changed: yet another change to signal handling in ecasound; - now two level response to signals is supported in - all stages of process termination -> first starting - normal cleanup and exit procudere, and with - second signal terminate immediately; see ecasound(1) - for the full story (new 'SIGNALS' section) - - changed: dropped "-funroll-loops" from the set of default - compiler options - - changed: comment out many entries in the global installed - 'ecasoundrc' file (entries are redundant as the same - defaults are already set in the program binaries) - - changed: optimized inner loops in core chain routing and - mixdown functions (with liboil if available) - - changed: optimized inner loops of -ea, -eadb, -eac, and -epp - - changed: dropped tracking of 'clipped samples' from -ev as - the results were of little use (and misleading) - - changed: '-ev' status output - - changed: cosmetic changes to the default ncurses trace output; - reduced number of subsystem-level trace messages - - changed: the name for default chainsetup created from command - line is now "untitled-chainsetup" - - changed: do not automatically connect chainsetups loaded - with '-s' - - fixed: mp3 output was broken with lame 3.98 (and newer); - the default lame parameters have now been updated - and have been tested with lame 3.96, 3.97 and with - the latest 3.98.2 - - fixed: bad audio with 'resample' object, non-integer sampling - rate change ratios and output to JACK; ecasound did - emit warning about this, but did not raise a fatal - error; now the underlying problem is fixed and now - 'resample' and 'jack' objects maybe safely used - together - - fixed: minor bug in ecamonitor; "cop-status" was used with - multiple chains selected - - fixed: don't use '--ignore-fail-on-non-empty' rmdir option - as it is not available on many platforms (e.g. OS X) - and this breaks the uninstall target; sfbug:2772628 - - fixed: bug in ecasound frontend parser for '-E' option that - broken passing arguments containing the substring - "-E"; introduced in 2.5.2 release - - fixed: stale audio was written to JACK output ports in case - of multiple streams, connected to different JACK ports, - reaching end-of-stream at different times [jedahu] -08022009 (v2.6.0) -** stable release **- - - note: key changes are described in more detail at: - http://eca.cx/relnotes/ecasound_v2_6_0_relnotes.txt - - added: new optional params to 'jack' -> 'jack,clientname,portprefix'; - replaces old interfaces 'jack_auto', 'jack_generic' - and 'jack_alsa'; see ecasound(1) for more details - - added: interactive mode - new commands 'jack-connect', - 'jack-disconnect' and 'jack-list-connections'; see - ecasound-iam(1) for details; closes sffeat:2134183 - - added: 'jack_multi', see ecasound(1); closes sffeat:1415822 - - added: ecasound options '--server', '--server-tcp-port' and - '--no-server'; these replace the misleading old - options '--daemon', '--nodaemon' and '--daemon-port', - which are now deprecated - - added: extended unit tests to cover option parsing, with - some initial test cases - - added: unit test framework - minor improvements including - abilitity to select which cases to run - - added: ECI - functions eci_ready() and eci_ready_r() added - to ecasoundc.h, and ECA_CONTROL_INTERACE::ready() - to the C++ API - - changed: deprecated 'jack_auto', 'jack_generic' and - 'jack_alsa' - - changed: numbering of JACK ports created with 'jack' and - 'jack_generic' starts from "_1" separately for - each prefix [dsacre] - - changed: deprecated 'ai-wave-edit', 'ao-wave-edit' commands - and the 'ext-cmd-wave-editor' ecasoundrc field - - changed: emit a 'subsystem' level trace message when - engine state changes to finished - - changed: interactive mode - minor update to 'status' command - output - - changed: compile libecasoundc as PIC code to make it possible - to use it from shared libraries; fixes problems - with e.g. Audio::Ecasound on amd64 architecture ; - closes sfbug:2505551 - - changed: ecasound option -f now accepts empty arguments for - sample format, channel count and sampling rate; empty - argument states that ecasound can pick a suitable - value, either the default value or e.g. the JACK - system sampling rate; updated documentation, see - ecasound(1) - - changed: minor update to ecasound's "--help" - - changed: when reading RIFF WAVE files, properly ignore - any unknown subchunk types - - changed: largefile support (+2GiB files) is now enabled - by default and configure uses's default autoconf - macro AC_SYS_LARGEFILE to perform the checks; - to explicitly disable, use '--disable-largefile'; - the old '--with-largefile' no longer has any effect - - changed: refactored ECI C impl code to get rid of all - fixed size buffers from the parser; this makes - the implementation more robust, reduces memory - usage and provides a small speed-up to most ECI - apps; closes sfbug:1412409 - - fixed: do not limit max-gain reported by '-ev' to [1,max] - value range - - fixed: avoid denormal numbers in '-ete' (leads to unusually - high CPU load) - - fixed: 'dump-cop-value' did not work as documented - - fixed: ECI - signal an error (e.g. eci_error() returns true) - if connection is lost to engine process (sync lost - or an other error) - - fixed: ecasignalview - exit if engine reports an error - during operation - - fixed: interactive mode - loop devices saved with incorrect - syntax, affects cs-save, cs-save-as and cs-edit ; see - http://eca.cx/ecasound-list/2009/01/0058.html - - fixed: problems when seeking back to start with setups using - loop devices; closes sfbug:2527049 - - fixed: segfault if using a tone generator input with a fixed - lenght, and a seek past the end of stream was performed - - fixed: aac/ogg/mikmod/mid inputs - once object reached state - 'finished' (all samples played), it cannot be played - again by reconnecting the chainsetup - - fixed: combination of '--server' and '-C' (disable interactive - mode) had a bug that prevented processing of commands - received over the server socket while the engine - was running the batchmode - - fixed: a nasty bug in 'playat' implementation causing audible - artifacts ; see - http://eca.cx/ecasound-list/2009/01/0089.html - - fixed: sndfile and audiofile backends - emit a warning if - a seek fails (e.g. when seeking beyond current - end-of-file for output objects) - - fixed: various improvements and fixes related to using - non-seekable audio objects (especially interactive - use);

It can be used for simple tasks like audio playback, -recording and format conversions, as well as for multitrack effect -processing, mixing, recording and signal recycling. Ecasound supports -a wide range of audio inputs, outputs and effect algorithms. -Effects and audio objects can be combined in various ways, and their -parameters can be controlled by operator objects like oscillators -and MIDI-CCs. A versatile console mode user-interface is included -in the package. - -Primary platform for running Ecasound is Linux. Ecasound also -works on many UNIX-derived systems such as FreeBSD and Solaris. -Limited support for Windows is available through Cygwin. - ------------------------------------------------------------------------ - How do you... (author: Kai Vehmanen) ------------------------------------------------------------------------ - -... spell the name? - -I haven't been very consistent with this, but at least in principle, -when capitalized, the name refers to the whole package. When in lower -case, it refers to the console mode application which happens to have -the same name. - -"Ecasound" = the whole package -"ecasound" = the console mode client application (binary) - -... pronounce the name? - -Any way you want! :) Personally I say something to the effect of -"eck-uh-sound". Start from "megasound", and omit pronouncing the -'m' at the start, and replace 'g' with a sharper 'k' sound, like -in the word "car". - ------------------------------------------------------------------------ - Story behind Ecasound (author: Kai Vehmanen) ------------------------------------------------------------------------ - -I started developing Ecasound because I needed an application to -record, process and mix my own music. The first versions of Ecasound -ran under IBM OS/2. I used those versions for finalizing my analog -4-track recordings. - -The analog 4-track - Tascam 414 - was a nice tool, but it -had its limits. So eventually I started looking for PC software -that supported multitrack recording. The first programs I used were -for Windows. I still used the OS/2 version of Ecasound for effects -processing and finalizing my mixes. Although I'm not fanatical -about operating systems, I did prefer (and still do) to use Linux -for my computing needs. I also hate rebooting between multiple -systems all the time, so it was time to do a port. - -When I ported Ecasound to Linux, a lot of functionality was rewritten -from scratch. During this work I also added multitrack capabilities -to Ecasound. It took quite a lot of effort to put it all back -together, but in the end I reached the point where I could do -all the audio processing tasks on Linux. As an additional benefit -I now had source code for - and thus control over - all tools I used -for audio processing. - -Nowadays I still use Ecasound for my music projects. This is also -the primary motivation for continuing the development work. There is -always something to improve. - ------------------------------------------------------------------------ - Requirements ------------------------------------------------------------------------ - -To run Ecasound, you need...: - -- Operating system that provides standard POSIX/SUS interfaces.

On some systems -Ecasound is part of the distribution and can be installed easily with -tools such as apt-get, yum and others. This is probably the easiest and -most straightforward way to install Ecasound. - -If you need to compile Ecasound, the file 'INSTALL' contains detailed -instructions on how to do this. - ------------------------------------------------------------------------ - Documentation ------------------------------------------------------------------------ - -Ecasound documentation is updated whenever new features are added -or existing features are modified. Some things are not documented -in great detail, but on the other hand, documentation is kept -up-to-date. So in short, correctness over volume. The primary -documentation sources are: - -- Ecasound User's Guide -- Ecasound Programmer's Guide -- Ecasound Control Interface Guide -- manual pages - - ecasound(1) - - ecatools(1): ecaplay(1), ecaconvert(1), ... - - ecasound-iam(1) - - ecasoundrc(5) -- misc HTML-formatted docs (Documentation/*.html) -- command line help - - ecasound --help - -Probably the best place to start is the examples section of -Ecasound's HTML-documentation (Documentation/examples.html). - ------------------------------------------------------------------------ - Mailing lists ------------------------------------------------------------------------ - -- ecasound-list at lists dot sourceforge dot net: - -A general discussion forum for developers and users of Ecasound and -related tools.

Active participation, -both from developers and users, is what pushes a FOSS project forward. - -Every succesful FOSS project has an active userbase behind it. This -means that your comments, ideas and bug reports are extremely -important. If something does not work, or some feature is missing, -be active. Either try to fix the problem yourself, or report it -on the ecasound-list mailing list. - -[1] Although Ecasound is free software (http://www.gnu.org), it also - fits the definition of open-source software (http://www.opensource.org/). - Although the two initiatives have different goals, they also share - a lot in common. The term FOSS is used to refer to both of them, - while still acknowledging the difference between the two. - ------------------------------------------------------------------------ - How stable is stable? ------------------------------------------------------------------------ - -Although publically released versions are called stable, this is not -a guarantee of any kind. Before releases, a small set of test cases is -run to verify that all basic features are working. The developers -also use the very latest versions themselves, so hopefully at least -all obvious bugs are found before stable releases are made. But -otherwise no guarantees are given. - -On the other hand, as Ecasound is free software, you have the -possibility to review the code yourself, perform tests, and fix any -bugs you might find, or get someone to fix them for you. In the end -you have the control. - -The more people there are participate in Ecasound development, testing -and related discussions, the better Ecasound will become! - ------------------------------------------------------------------------ - Authors ------------------------------------------------------------------------ - -See the file 'AUTHORS'. - ------------------------------------------------------------------------ - Thanks to ------------------------------------------------------------------------ - -DotCX (www.nic.cx) - For providing 'eca.cx' domain free of charge 2000-2004. -SEUL (www.seul.org) - For hosting Ecasound CVS, ftp, and http services since 1999. -SourceForge.net - For hosting Ecasound, Ecawave and Ecamegapedal ftp and - http mirror sites since 1999. -Wakkanet Oy (www.wakkanet.fi) - For various hosting services 1999-2004. - -Linux-audio-dev community - Always a great source of inspiration!

Complete with context sensitive -;; completion and interactive features to control the current process -;; using ECI. -;; -;; * Ecasound Control Interface (ECI) library for programmatic control -;; of a Ecasound process. This allows you to write Ecasound batch -;; jobs in Emacs-Lisp with Lisp functions and return values. Have a -;; look at eci-example and ecasound-normalize. -;; -;; * ecasound-ewf-mode, a mode for editing .ewf files. -;; -;; -;; Usage: -;; -;; You need at least ecasound 2.2.0 for this file to work properly. -;; -;; Put ecasound.el in your load-path and require it in your .emacs. -;; Set `ecasound-program' to the path to your ecasound executable. -;; -;; (setq load-path (cons "/home/user/elisp") -;; (require 'ecasound) -;; (setq ecasound-program "/home/user/bin/ecasound" -;; eci-program "/home/user/bin/ecasound") -;; -;; To set ecasound startup options use -;; -;; M-x ecasound-customize-startup RET -;; -;; Then use M-x ecasound RET to invoke an inferior ecasound process. -;; -;; For programmatic use of the ECI API, have a look at `eci-init', -;; `eci-command' and in general the eci-* namespace. -;; -;; Compatibility: -;; -;; This file is only tested with GNU Emacs 21. I've invested some minimal -;; efforts to get it working with XEmacs. However, XEmacs support -;; might be broken in some areas. Since I personally very seldomly -;; use XEmacs, I am happy about suggestions and patches. -;; -;; Todo: -;; -;; * Find a better way to do status info fetching... -;; * Add more conditions to the menu. -;; * Use map-xxx-list data in the ecasound-copp widget. This means we -;; need to merge cop-status and map-cop-list data somehow or have -;; the cop-editor fetch hints from map-cop/ladpsa/preset-list. -;; * Make `ecasound-signalview' faster, and allow to invoke it on already -;; opened sessions. -;; * Fix the case where ecasound sends output *after* the prompt. -;; This is tricky! Fixed for internal parsing, probably will leave -;; like that for interactive use, not worth the trouble... -;; * Copy documentation for ECI commands into eci-* docstrings and menu -;; :help keywords. -;; * Expand the menu. - -;;; History: -;; -;; Version: 0.8.3 -;; -;; * ecasound-cli-arg:value-to-internal: Use `widget-get' instead of -;; (car (last elt)) to extract :value from :args which makes code compatible -;; to XEmacs. -;; * ecasound-cli-arg:value-to-external: Use `widget-get' instead of -;; `widget-apply' to fetch :arg-format. Makes XEmacs happy. -;; * Add "-D" to the default `ecasound-arguments'. This fixes a problem -;; with the TERM variable which only appeared in XEmacs and is a reasonable -;; default anyway. -;; * Fix `ecasound-output-filter' when "-D" is used as argument on startup. -;; * Add `comint-strip-ctrl-m' to `comint-output-filter-functions' when -;; we are running XEmacs. -;; * `defeci' cs-set-position. Bound to "M-c M-s s" and in -;; `ecasound-iam-cs-menu'. -;; * Add some more docstrings. -;; * New interactive functions `ecasound-set-mark' and `ecasound-goto-mark' -;; which implement the position marker system discussed on ecasound-list. -;; Bound to C-c C-SPC and C-c C-j respectively. -;; * New user variable `ecasound-daemon-host' which defaults to "localhost". -;; * Record the daemon port in a buffer local variable `ecasound-daemon-port' -;; and therefore allow temporarily binding `ecasound-arguments' to something -;; different via e.g. `let' before invoking `ecasound'. -;; * Fix regexp in `eci-input-filter' to be XEmacs compatible. -;; -;; Version: 0.8.2 -;; -;; * Added quite some missing docstrings. -;; * New variable `ecasound-last-command-alist'. Use that to do fancy stuff -;; to certain commands return values. -;; * New variable `ecasound-type-alist'. Normally you should not need to -;; change this, but it's nice to have it configurable. -;; * New function `eci-is-valid-p'. Rationale is that nil as return -;; value of a ECI command should indicate an error. So this function -;; with a -p suffix to use as a predicate. -;; * New variable `ecasound-parent' holds the parent buffer in a daemon buffer. -;; * New variables ecasound-timer-flag&interval. -;; * Renamed `eci-output-filter' to `ecasound-output-filter'. -;; * New variable ecasound-mode|header-line-format. -;; * `ecasound-cop-edit' now uses cop-set instead of -;; cop-select+copp-select+copp-set to update values. -;; * Fixed multiple-argument handling. They are separated with ',', not -;; with a space. -;; * New variable ecasound-sending-command, used to prevent the background -;; timer from coliding with other ECI requests. -;; -;; Version: 0.8.1 -;; -;; * Make ai|ao|cs-forward|rewind use ai|ao|cs-selected in the prompt -;; string of the interactive spec. -;; * New keymaps ecasound-audioin|audioout-map. -;; Now you can be very quick: -;; M-x ecasound RET M-i a
