***********************************************************************
19082010 (v2.7.2) -** stable release **-
- added: manual gate (-gm); see ecasound(1) man page
- changed: liboil now enabled by default if the library
development files are available when running
configure
- fixed: bug with 'resample' objects and early seeks (e.g.
with '-y' offsets); reported by Artur
- fixed: bugs in kvutils that broke some old/non-glibc
builds (e.g. cygwin); bug reported by Al Oomens
- fixed: bugs in saving chainsetups with stacked audio
objects ("audioloop", "select", "playat")
20022010 (v2.7.1) -** stable release **-
- note: key changes are described in more detail at:
http://eca.cx/relnotes/ecasound_v2_7_1_relnotes.txt
- fixed: glitches in ALSA capture/playback with some sound
hardware/configurations, and using alsa-lib
older than 1.0.15; related to deprecated ALSA API
function snd_pcm_sw_params_set_xfer_align()
- fixed: bug in removing audio objects when disk double
buffering is used (-z:db); could cause a segfault
in some scenarios (e.g. with ecasignalview)
- fixed: interactive mode; c-selected segfauls if issued
with no chainsetup selected
- fixed: build errors when no liblo is available
- fixed: interactive-mode; cs-setpos, cs-rewind and cs-forward
did not work if chainsetup was connected, and no
chains (or an invalid chain) was selected; bug
reported by Joel Roth
- fixed: ecalength choked filenames with whitespace; patch
from FUJI project
(http://students.mimuw.edu.pl/~tk197881/a8cas/)
17102009 (v2.7.0) -** stable release **-
- note: key changes are described in more detail at:
http://eca.cx/relnotes/ecasound_v2_7_0_relnotes.txt
- added: new exit code of '4' to ecasound; 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); in most cases this means graceful recovery
from failed seek attempts, and correct reporting of
the objects actual current position
- fixed: error is emitted if trying to use 'select' with
objects that do not support seeking
- fixed: bugs with passing 'auto' as the 2nd parameter of
'resample'
- fixed: bug with seeking resampled audio objects
- fixed: bug in combined use of 'audioloop' and 'resample'
- fixed: catch and warn about various errors cases when
given incorrect or missing params to audio
types: typeselect, resample, reverse, playat,
audioloop, select
24082008 (v2.5.2) -** stable release **-
- more verbose description of change available at:
http://eca.cx/relnotes/ecasound_v2_5_2_relnotes.txt
- fixed: bug in channel routing of LADSPA plugins that have
more audio output ports than input ports
21082008 (v2.5.1) -** stable release **-
- more verbose description of change available at:
http://eca.cx/relnotes/ecasound_v2_5_1_relnotes.txt
- fixed: a last minute change in 2.5.0 that caused build errors
with gcc-4.3.1 if ALSA support is disabled
- fixed: a change in 2.5.0 how process cleanup is initiated from
the signal handler caused severe problems on some
systems when ecasound was interrupted with e.g.
ctrl-c/SIGINT; worst case was a crashed X session which
is of course really, really bad
- fixed: a bug in registering LADSPA plugins; on some systems
not all found plugins were registered properly to
ecasound's object maps causing some plugins to be
unusable; errors
16082008 (v2.5.0) -** stable release **-
- more verbose description of change available at:
http://eca.cx/relnotes/ecasound_v2_5_0_relnotes.txt
- notice: slightly modified the version numbering scheme -
minor version is incremented whenever non-trivial
new features are added
- notice: verified to compile with minimal warnings with
gcc-4.3.1
- edi-entries: edi-40 closed (Update to error and warning
reporting mechanisms), edi-38 closed (see
edi-7 partially implemented
- added: ecasound.el: added missing ECI commands cs-option,
cs-set-length, cs-set-position-samples, ai-get-length,
ai-set-position, and ai-set-position-samples [dto,
mlang]
- added: tone generator input; '-i:tone,sine,440,10.3' will
create a 440Hz sine tone with duration of 10.3 seconds;
this input type will be especially useful for reproducing
bugs in complicated chainsetups, without the need to
exchange complete session data (which usually are composed
of large amounts of audio data)
- added: audio looper object; "-i:audioloop,foo.wav" will play
'foo.wav' and loop it indefinitely
- added: audio selector object; "-i:select,5,15.2,foo.wav" will
play 15.2sec of "foo.wav", starting at position 5sec;
relates to (edi-7)
- added: audio play-at object; "-i:playat,5,foo.wav" will
start playing "foo.wav" after position reaches 5sec
- added: EWF files; ability to specify positions in time in
sample frames; "2.0" is interpreted as 2.0secs while
"88200sa" is interpreted as 88200 samples
- added: 'reopen-count' parameter to threshold gate (-ge);
for instance when recording vinyl/tapes, this allows
to automatically restart recording when a new track
is started [andrewl]
- added: ecasound frontend option '-E "cmds"' that allows
to run a set of interactive mode commands at
startup; see ecasound(1) for details; closes (edi-38)
- added: a notice is printed in case audio object's audio
format parameters differ from the chainsetup's default
values (audio object's own params always override
any value set by e.g. '-f:...').
- changed: most of the EWF support (Ecasound Wave Files, .ewf)
has been rewritten in this version; numerous bugs
are fixed
- changed: eaim - commands 'cop-add' and 'ctrl-add' now allow
an alternate syntax: both "-<id_string>:par1,...,parN"
and "<id_string>:par1,...,parN" are now accepted
- changed: ability to write to EWF file is now marked as
a deprecated feature which will be removed in
a later release
- changed: mechanism to terminate forked child processes;
properly wait for process termination in all
circumstances (previously there were some
unhandled corner cases)
- changed: major updates to the examples.html page (available
also at http://eca.cx/examples )
- changed: refactored logic for propagating seek events
across chainsetups; warnings are now issued if
one tries to seek objects that do not supports
seeking; similarly warning is issued if a given
audio object type doesn't support sample accurate
seeks (for example mp3 inputs have this limitation)
- changed: updated ecasound(1) man page description of '-klg'
- changed: separate global (-d, -R, ...) and ecasound frontend
specific (-c, --daemon, -s, ...) options in
ecasound(1) man page
- changed: changes to "cs-status" (aka "status", "st")
output formatting; now more information about
selected and connected setups is printed out
- changed: minor changes to the information printed out when
open audio input/outputs
- changed: pipes, sockets and device nodes in LADSPA plugin
directories are skipped (previously hidden files
were already skipped)
- changed: loop device identifier was changed from an integer
to a generic string; both "-i:loop,1" and
"-i:loop,myloop" are now valid
- fixed: incorrect usage of the Python C API, which leads to
segfaults when pyecasound is used under python2.5;
fixes Debian bug #468965
- fixed: bugs in ewf-looping code
- fixed: avoid terminating processing when invalid parameters are
passed to channel copy (chcopy/erc), mix (chmix/erm) and
move (chmove) chainops
- fixed: eaim - buffering mode was sometimes incorrectly
reported in 'cs-status' output (-B:auto instead of
the actual set buffering mode) output; bug reported by
Jan Weil
- fixed: compilation warnings from GCC-4.3; fixes Debian bug
#454890, patch from Cyril Brulebois
- fixed: bug in passing multiple arguments to 'typeselect',
'resample', and 'resample' objects
- fixed: with some glibc versions (tested with 2.3.6.ds1-13etch5),
ecasound did not fully clean up all threads when
it received a signal and terminated; the bug showed
up as a stuck thread, with backtrace pointing to
pthread_onexit_process()
- fixed: compilation issue on Mac OS X 10.5 [grobian]
- fixed: bug in saving control state with 'cs-save' or
'cs-save-as'; triggered if controller was followed
by more chainops on the same chain
- fixed: bugs with preserving state across seeks with
many controller objects (-kl, -kl2 and -kos)
- fixed: a bug in ecasound user's guide w.r.t. usage of
loop devices
- fixed: sloppy parsing of "-i:loop" and "-o:loop" arguments
leading to confusing error messages when invalid input/output
objects, containing the substring "loop" were passed
as arguments to "-i" and "-o"
14082007 (v2.4.6.1) -** stable release **-
- fixed: extra debugging, printed to stderr, for resource file
values was accidentally left enabled in the 2.4.6 release
14082007 (v2.4.6) -** stable release **-
- more verbose description of change available at:
http://eca.cx/relnotes/ecasound_v2_4_6_relnotes.txt
- added: new option '-R:path-to-resource-file' to use a custom
resource file and disable querying of global and user
resource files; as a special case, by setting this
to '/dev/null', one disable all access to resource
files; requested by Klaus Schulz and Keith Creasy
- added: eiam - new command 'resource-file'; see ecasoundrc(5)
man page; related to previous item
- changed: license of rubyecasound, the Ruby ECI API
implementation, has been changed from GPL to LGPL
- fixed: build errors caused by missing #includes, reported
by GCC 4.3; bug report from Debian, bug #417178
- fixed: rounding errors with small buffersizes caused time crop
gate (-gc) to function incorrectly; reported by Joe
Planisky
- fixed: force localization of decimal numbers to "POSIX" (i.e.
use period as the separator) to avoid bugs with
e.g. LADSPA plugins that call setlocale and break
the ecasound option parser; for instance all swh-plugins
call setlocale; reported by R<>mi Rouaud
- fixed: printing chain operator (e.g. the '-ev' operator) status
at end of sessions was broken in 2.4.5; reported by
Julien Claassen
- fixed: bugs that led to infinitely running chainsetups when
loop input/outputs were used; reported by Aaron Heller
and Etienne Deleflie
- fixed: incorrect page numbers in table of contents of
the Ecasound Programmer's and User's Guides; patch
from Junichi Uekawa
- fixed: segfault when removing a chain operator with multiple
associated controllers; reported by Adam Linson
07122006 (v2.4.5) -** stable release **-
- more verbose description of change available at:
http://eca.cx/relnotes/ecasound_v2_4_5_relnotes.txt
- added: ability to compile without a readline library (will
disable the curses based console user-interface)
- added: if libsndfile is found and supports flac (sndfile
1.0.12 or newer), it will be used as the default
handler for flac files; use of sndfile makes random
access for flac files possible (for example seeking
in interactive mode)
- added: section on 'RETURN VALUES' to ecasound(1) man page
- added: ecasound-iam(1) - added documentation for error
return values for 'run', 'start' and 'cs-connect'
- added: ECASOUND_LOGFILE and ECASOUND_LOGLEVEL environment
variables; see ecasound(1) for documentation

the examples page at eca.cx/ecasound
- added: new chain operators '-chmove' and '-chmute'
- added: new aliases for chain operators: '-chmix' for '-erm',
and '-chcopy' for '-erc'
- added: ability to protect EOS arguments, like filenames, with
double quotes, closes bug #1456510; see also the related
BUGS entry about handling commas in filenames, and
updated documentation in ecasound(1), ecasond-iam(1)
and the User's Guide
- removed: readline-4.0 subdir from the dist package; system
readline library is now the only build option
- changed: ecasoundrc - added "-f" to the default flac
output exec command (although now libsndfile's
flac support is the default)
- changed: improved libsndfile integration, any libsndfile
supported file format can be used as output for
'sndfile,foo.ext' (format selected based on filename
extension)
- changed: eiam - default int-log-history length set to zero
- changed: updated config.guess and config.sub to more recent
versions (timestamp 2006-07-02)
- changed: updated the documentation for 'ai-select/ao-select',
it is no longer required that input/outputs have
a unique name within one chainsetup; problem reported
by Kurt Konolige
- changed: replaced the ECI C implementation's (libecasoundc)
engine cleanup mechanism with a much more robust one
- changed: the engine will now refuse to start if a start offset
is given with '-y:secs' for an object not supporting
seeking; this has been a very common source of
end-user confusion
- fixed: segfault when removing loop devices with a[io]-remove,
reported by Pedro Antonio Fructuoso Merino
- fixed: incorrect headers in created flac files (not related
to sndfile/flac); fix can possibly affect other file
formats handled by external apps (aac, midi, mikmod,
mp3 and ogg files), problem reported by Florian Ladstaedter
- fixed: errors during batch processing (running out of file
space, etc) were not reported as a non-zero process
return value, problem reported by Zrajm Akfohg

- fixed: ecasignalview build errors on cygwin [hawk777]
- fixed: segfault when parsing "\" in interactive mode, reported
by Koen [pfructuoso]
- fixed: a subtle race-condition in the cleanup routines leading
to segfaults when breaking a batch run with ctrl-c
- fixed: bug causing audible glitching when seeking with
chainsetups containing loop devices [pfructuoso]
- fixed: "rw 0" caused the engine to skip ahead multiple
seconds (reported by Kurt Konolige)
- fixed: segfaults from invalid params to -f option, for
example "-f:16" or "-f:16,2", reported by peppo on
#lad at freenode.org
- fixed: a severe string termination bug in libecasoundc
that led to garbled output from ECI commands
returning lists of strings, reported by Brad Bowman,
Joel Roth and Stuart Allie
27012006 (v2.4.4) -** stable release **-
- more verbose description of change available at:

- fixed: bug in seeking mp3 files
- fixed: eiam - 'c-select' caused a segfault if no chainsetup
was selected
- fixed: -etf:0 caused a segfault
- fixed: severe bug in mixdown code - in cases where an input
is connected to multiple chains, and one or more inputs
have reached end of stream, the resulting mix is not
handled properly
- fixed: bug in freeing references to buffers in effect preset
code; triggered by externally terminating an ecasound
session containing preset objects (sfbug:1412200)
- fixed: ECI-C memory access errors reported by valgrind
- fixed: allow commas in ecasignalview input/output params;
makes it again possible to specify ALSA devices, etc

- more verbose description of change available at:
http://eca.cx/relnotes/ecasound_v2_4_3_relnotes.txt
- added: support for ALSA sequencer support; see ecasound(1)
and examples.html [pedrolc]

- fixed: problems in saving ewf objects with cs-save,
cs-save-as and cs-edit [kaiv]
- fixed: controllers were always added to the last
chainop, not to the selected chain operator [allies]
- fixed: --enable-jack and --disable-jack both disabled JACK
support [kaiv]
- fixed: serious bug in the "reverse" audio objects, caused
audible noise in the reversed signal [kaiv]
- fixed: segfaults at exit when LADSPA plugins had been used;
the error did not happen every time and with every type
of plugin; problem was a race between atexit handlers
of ecasound, and the dynamically loaded plugins [kaiv]
- fixed: ecasignalview - do not send or receive transport
events [kaiv]
- fixed: ecasound daemon mode, correctly print hostnames without
resolvable hostname
08042005 (v2.4.1) -** stable release **-
- more verbose description of change available at:
http://eca.cx/relnotes/ecasound_v2_4_1_relnotes.txt
- note: verified to work with automake versions 1.6 and 1.9;
automake 1.5 and older, as well as autoconf versions
older than 2.50, are no longer supported; these
changes only affect users of Ecasound CVS checkouts
- added: ecaplay - better error reporting, feature to reset
output device audio parameters for each new input
file, support for ECAPLAY_OUTPUT_DEVICE environment
variable; see ecatools(1) for more info
- added: playlist mode to ecaplay (new -q, and -p options;
see ecaplay(1) for more info)
- added: "Supported automake/autoconf features" section to
the INSTALL file
- added: new presets to the default effect_presets file
- added: support for describing full range of preset parameter
flags with -ppt (see effect_presets file and the
relevant sections in User's Guide)
- added: new sections on preset parameters to User's Guide
- added: allow reseting ecasignalview max-peak and clipped-samples
counters by sending a SIGHUP to the process
- changed: moved definitions from acconfig.h to configure.in;
gets rid of the AC_DEFINE warnings produced by
recent versions of autoheader
- changed: Ecasound Programmer's Guide converted from LaTeX
to ascii/rst
- changed: sed is used to generate ecasoundrc at make; allows to
specify a custom pkgdatadir when running make [junichi]
- changed: various small improvements to all ecatools and
the related manpages
- changed: updated config.guess and config.sub to more recent
versions (timestamp 2005-03-24)
- changed: various updates to the README file
- fixed: sources for the aRts plugin were not present in the
2.4.0 release package
- fixed: mp3-header parsing code has been partly rewritten;
the new parser is designed to better handle garbage
and unknown frame types in mp3 files [juliand,kaiv]
- fixed: compile errors with egcs-2.91.66
- fixed: current position of the time crop gate (-gc) was
incorrecly increased [alexey]
- fixed: compilation failed if building outside srcdir
- fixed: ECI C impl. did not properly release all file handles
in eci_cleanup(); for example playing thousands of
files with ecaplay would cause the system to run
out of file descriptors (too many open files error)
- fixed: bug in handling LADSPA plugins with colon chars in
their port descriptions (such as the SC1-4
compressors)
- fixed: do not print "Session created" even if -q option has
been given (quiet output mode)
12032005 (v2.4.0) -** stable release **-
- more verbose description of change available at:
http://eca.cx/relnotes/ecasound_v2_4_0_relnotes.txt
- edi-entries: edi-40 progress
- added: support for having commas in arguments by escaping
them with a backslash (example: "ai-add foo\,bar.wav")
- added: pretty-printing of ecasound output; wrap output so
so that all lines fit into 74 columns; does not affect
wellformed output mode nor stderr output (-D)
- added: new section about handling commas in filenames to
Ecasound User's Guide
- added: eiam - new 'int-log-history' command to query
recent log messages sent by libecasound; this is a very
useful tool for debugging ECI scripts and apps
- added: eiam - new 'int-set-log-history-length' command to set
log history length; default to 5 items
- added: resample-lq (low-quality) audio object to force using
the internal resampler even though support for
libsamplerate is enabled at build time
- added: support for sum-mixmode; enabled with -z:mixmode,sum;
the old average mixing is still the default; see
ecasound(1)
- added: ecasoundrc - 'mix-mode' setting; see ecasoundrc(5)
- changed: more helpful messages to explain why a chainsetup
cannot be connected to the engine
- changed: EIAM - when returning a list of strings, all commas
in list elements are now escaped with backslashes;
this is done to avoid ambiguity in parsing
- changed: new default debug level of 271
- changed: new optimized message queue implementation used in
communication between the engine and the interface
subsystems; solves a few remaining corner cases
where ecasound could block in real-time critical
code-paths

with -el/-eli
- changed: removed hard upper-limit for -ei scale-factor,
modified both the upper and lower soft limits

- fixex: setting radius params of -etc comb filter
- fixed: make check target failed in readline-4.0 subdir
- fixed: avoid segfault when receiving a bufsize or srate
change event from JACK; ecasound still cannot change
bufsize or srate on the fly, but at least it now fails
gracefully
- fixed: always pass filename (%f) as one parameter to the
external apps; fixes bug present in 2.3.4 and 2.3.5
releases which broke handling spaces in filenames;
affected all file formats handled via external tools
(ogg/mp3/flac/m4a/...); also a separate bug in handling
spaces in ogg output filenames was fixed
- fixed: occasional bugs with rubyecasound in handling the
EIAM 'quit' command; this also fixes the errors in
running 'make check' in ecasound/rubyecasound
- fixed: serious bugs in resampling between 96000 and 44100/48000
rates when using libsamplerate; upgraded Ecasound to use
the libsamplerate 'full API'
- fixed: options "-b:", "-b" and "-b:0" caused a segfault
- fixed: aac/m4a encoder was not stopped properly after
processing was finished

command has completed; caused commands such as
'cs-set-position' to fail when used after 'run'

guides) are now generated using AE fonts; the PDFs
can now be read with readers like xpdf and
probably look better in others [janweil]

- changed: pyecasound - the native python impl (ecacontrol.py)
now returns an error if communication with the
ecasound process times out

- added: -d, -dd and -d command-line options, see ecasound(1)
- added: recording offset parameter -z:multitrack,offset option
- changed: to avoid resampling faults, upper limit of 2000%
set for pitchshifter's (-ei) shift-% arg; note! high
values of shift-% can still cause crashes if using
libsamplerate
- changed: if available, use pthread API for setting scheduler
params; might improve real-time reliability on
rh9.0 machines and others that have NPTL
- changed: pyecasound - redefined configure option
--enable-pyecasound=IMPL where 'IMPL' is either
'c' or 'python'; --disable-pyecasound disables
them both
- changed: pyecasound - if ecasound's build prefix does not
match the python prefix, /usr or /usr/local,

feedback loop if processed with certain effects
and mixed with audio from other chains
- fixed: ewf length and offset errors with sample rates
different from default (usually 44.1kHz)
- fixed: chainsetup samplerate incorrectly set with some
configurations; caused problems with -t:xxx and
other functions related to chainsetup level position

different number of channels to one output; audio
from previous mixdown rounds leaked to unused
source channels
- fixed: some chainsetup parsing errors were totally ignored
and not reported to the user

certain locales (for example "fi_FI")
- fixed: without at least one '-Md' or one '-km' option
specified, MIDI-services did not work
- fixed: pulse gate timing inaccuracy (-eemp); also affected
the bpm pulse gate (-eemb) and thus the metronome
preset (-pn:metronome)
- fixed: a 'setpos' on a not yet connected chainsetup would
cause seeks to the wrong position for objects with
non-default samplerates

- changed: jack_auto,dstclient input/output object now
automatically connects to matching ports of JACK
dstclient (no longer requires dstclient to have
in_X/out_X port names)
- fixed: yet another fix for creating temporary files in
ecanormalize and ecafixdc; now both LOGNAME and USER
are checked for a valid user name
- fixed: prefer usleep over nanosleep on cygwin; avoids
the excessive-cpu-usage problem
- fixed: work-around for a bug in the pcm plugin of ALSA 0.9.1
and earlier that caused recording/playback to
stop to an audio i/o error
- fixed: inconsistencies in how configure --disable/enable-feat
options were handled

fetch the correct bufsize and srate parameters from
the JACK server when connecting a chainsetup with
JACK inputs or outputs

resampling library; used both by the resample
audio i/o object and the pitch shifter chainop (-ei);
enable with --with-libsamplerate
- added: --disable-libsamplerate; don't enable libsamplerate
support even if the library is found during configure
- added: resample-hq audio object type; like resample, but
use the highest available resampling quality;
currently only has an effect if libsamplerate
support is enabled
- added: alternative UNIX signal handling for platforms that
don't provide sigwait() (cygwin is one)
- changed: ecasoundrc - ladspa-plugin-directory can contain
multiple directories, separated by colons; this
change was done to avoid any confusion with
the LADSPA_PATH syntax and ecasoundrc
- changed: rewritten much of the JACK slave-mode code; enables
much faster and reliable transport-sync
- fixed: compiling pyecasound failed on alpha w/ gcc-3.2

audio object manager level options
- added: -G:jack,client_name,operation_mode option; see

man page for better documentation
- added: pyecasound - if python version is 2.2 or higher,
pyeca.py sets custom dlopen flags before importing
the actual pyecasound python module; this makes it
possible to access ecasound's plugins (ALSA, JACK,
libaudiofile) from python ECI apps
- added: ecasoundrc - 'default-audio-format'; same syntax
as with the -f option; defaults to s16_le,2,44100,i

-y can't be used for setting the loop start
offset -> ewf-files should be used instead
- changed: s24_le and s24_be sample formats are interpreted
as three-byte values, not as four-byte
24-in-32bits values as before; to access
unpacked 24bit data, use s32_le and s32_be
formats instead
- changed: configure.in cleanup
- changed: the libkvutils binary API has changes so its
version number was changed from 3:0:1 to 3:0:0

setup was not valid for reconnection
- fixed: -klg didn't work as documented
16012002 (v2.1dev7)
- edi-entries: edi-12
- added: a watchdog thread that handles thread cleanup;
this is needed especially for audio and chainop
objects which create their own threads (like jack)
- changed: unification of interactive and passive
modes; running ecasound without -c is now
pretty close to "echo run | ecasound -c cmds"
- changed: if an invalid chainsetup is given on the command
line, and -c is given, ecasound will print an
error but will not exit as it did before; you
can continue editing in the ia-mode to check
what was wrong in the setup
- changed: compilation of eca-iamode-parser.cpp is now
significantly faster and takes less resources;
this should fix problems with compiling ecasound
on machines with <256MB of memory

of cmd-line options as iactive-mod commands (like
"-i:file.wav") is still supported, "cs-option

- removed: adding chain operators to multiple chains is no
longer possile - this makes the library interface
more powerful as client programs can have direct
access to chainops they've added (see
eca-controller.h for details)
101199 (v1.6.1d6)
- added: most interactive-mode commands are now implemented
- added: new ia-mode commands: c-mute, c-unmute, c-process,
c-select-all, cs-save-as,
- added: documentation for nearly all implemented ia-mode
commands, see ecasound-aim(1)
- changes: major changes in RPM-packaging
- fixed: a very nasty bug in dynamic ALSA-support
- fixed: some effects caused core dumps (bug in the sbuf
iterator routines)
- fixed: many minor bug fixes
- removed: ia-mode commands: exec, end
081199 (v1.6.0d6)
- added: iactive mode now uses GNU readline for user input
- command-line editing, command history and command
completion (use .inputrc for configuring)
- added: 30-40 new interactive-mode commands
- added: ecasound-iam(1) manual page - interactive mode
documentation
- added: ecasound user's guide and programmer's guide
- added: 'default-to-precise-sample-rates' to ecasoundrc -
whether to ignore sample rate differences (and
possibly avoid resampling), affects OSS-devices,
defaults to 'false'
- added: -z:psr option (see above)
- changed: reimplemented signal handling using POSIX
signal handlers (ANSI interface was used before)
- changed: divided all the bigger modules into smaller
classes and files (these big modules were
causing lots of compiler and resource problems)
- changed: major internal changes (multichannel chain operators,
improved mixing algorithms, etc)
- changed: rewritten mp3-support (still using mpg123 and lame)
- changed: lots of changes in handling external resources
(wave and text editors, mpg123 and lame parameters,
etc.) - see 'man ecasoundrc'
- removed: looping (interactive-mode loop commands)
- removed: 'sfx' command (iactive-mode)

support)
- fixed: extra noise when upsampling
- fixed: qtecasound - chainsetup's name was changed to
tempfile name if edited with an external editor
- fixed: qtecasound - conflict with Qt-libs when

120999 (v1.5.11r5)
- added: ldconfig is now always run after (un)install of
binary RPM packages
- added: if underruns/overruns occur when using ALSA devices,
a warning message is given on exit (stderr)
- changed: gcc's -fomit-frame-pointer isn't used anymore
(caused lots of problems with exceptions)
- fixed: ecasound tried to use ALSA headers even though
--disable-alsa was given (eca-alsa-dyn.h and
eca-midi.h)
- fixed: audiofx_compressor.h tried to include obsolete
error.h header file
- fixed: pan effect (-epp) decreased overall volume level

directory
- added: a much more elegant system for dynamically loading
ALSA support
- added: support for ALSA MIDI devices (/dev/snd/midiCxDy)
- changed: rewrote the MIDI-input sybsystem (works better
with multiple controllers)
- fixed: kvutils -package also needed configure script fixes

- fixed: although "make install" worked in all cases,
plain "make" didn't work if installing ecasound
1.5.x for the first time
- fixed: crashed if you had two chainsetups with ALSA devices
and you tried to delete the other one
- fixed: crashed in some conditions when closing .wav and
.raw files
040999 (v1.5.9r5)
- changed: qtecasound - in all windows with list widgets,
if no item is selected, current item (if any)
is used for all operations
- changed: in most cases, '-r' option (raise priority) isn't
needed anymore (see ecasound and ecasoundrc man
pages for more info)
- changed ecasoundrc - 'x-text-editor-use-getenv' is now
'true' by default
- fixed: resonant lowpass filter was once again broken
- fixed: configure should now recognise FreeBSD's pthread
implementation (not tested yet)
- fixed: in some rare cases, engine was started in interactive
mixmode while the interface was in passive mode
(-> program started but didn't do anything)
030999 (v1.5.8r5)
- added: '!' shortcut to all windows (keyboard focus to
control panel)
- changed: some Makefile changes for excluding static
ecasound libraries from the binary dist packages
(managed to shrink binary-rpms by nearly a 1MB!)
- fixed: qtecasound - shortcut-key fixes in chainsetup window
- fixed: qtecasound - waveform view positioning is now much
more precise than before
- fixed: qtecasound - core dumps when exiting
020999 (v1.5.7r5)
- added: qtecasound - chainsetup window now has a wave-edit
button which loads the active file into a external
wave editor; defaults to "snd", can be changed by
changing the value of "x-wave-editor" in
~/.ecasoundrc
- added: qtecasound - support for external text editors
(can be launched from session window) - saves the
active chainsetup to a text file, loads it to an
editor and afterwards updates file's content back
to ecasound - if "x-text-editor-use-getenv true"
is specified in ~/.ecasoundrc, ecasound uses
EDITOR environment variable if it's available,
otherwise value of "x-default-text-editor" is
used ... an of course, default value for this is
the ultimate musicians tool: emacs! ;)
- changed: qtecasound - some minor changes to session and
chainsetup widgets
- changed: .ews format (wave view cache files) has changed,
ecasound can still read the old format
- changed: qtecasound - "activate" button changed to a
"change status" button which rotates through
inactive->active->connected->inactive ...
- fixed: qtecasound - enabling/disabling chains sometimes
resulted in program crashes
- fixed: all structs found in ecasound source code now
use the standard type definations from sys/type.h
(format "[u_]int'bits'_t") - this should solve some
compatibility problems with non-x86 platforms -
thanks for Guenter Geiger for notifying about these
- fixed: a few fixes to the new double-buffering system -
lots of buffer parameter fine-tuning
290899 (v1.5.6r5)
- added: "-z:feature" command line option for enabling
misc features
- added: mmap-based double-buffering now disabled by
default, enable it with "-z:db" or by putting
"default-to-double-buffering true" to your
~/.ecasoundrc
- added: when upgrading ecasound, new resource values
will be automatically added to your ~/.ecasoundrc
- fixed: crashes when getting error messages from alsa-lib
(for instance when using invalid card and device
numbers)
- fixed: a few Makefile problems in 1.5.x versions
(thanks for Vadim Tkachenko for reporting these)
280899 (v1.5.5r5)
- added: improvements to resource file (~/.ecasoundrc)
handling - resource files can now have comment
lines (lines beginning with a '#'); resource
files are rewritten only if resource values are
changed directly from ecasound; '=' sign can be
used as a name-value separator
- fixed: since version 1.5.2r5, .cdr input/output hasn't
worked (reversed byteorder when reading .crd
files, .cdr output files weren't padded correctly)
270899 (v1.5.4r5)
- added: experimental support for double-buffered
mmap() file i/o (currently implemented
for .wav/.raw input only)
- fixed: thread-priority was always risen (once again)
210899 (v1.5.3r5)
- added: a lowpass filter effect (-ef2); not as good
as the other lowpass filters (-efl and -ef3), but
should be a bit faster
- fixed: 1.5.2r5 was really _slow_ (a file seek bug)
200899 (v1.5.2r5)
- added: "-x" command line option - truncate outputs
- added: sample rate conversion (resampling) - if audio
object's sample rate differs from ecasound's
internal rate the signal gets resampled
(internal rate is currently 44100; can be
changed from samplebuffer.h)
- changed: gcc 2.95.1 is now used when developing
ecasound; precompiled packages require libstdc++
2.10.0 (comes with gcc 2.95.1) or newer
- fixed: few minor fixes to the noisegate effect
- fixed: upon creation, more precision is used to print
effect parameters
190899 (v1.5.1r5)
- fixed: problems with filters
180899 (v1.5.0r5)
- added: ecatools package which now consists of programs
ecatools_normalize, ecatools_fixdc and
ecatools_play - see ecatools(1) man page
- changed: ecasound and qtecasound now have their own
source trees; rest of ecasound is compiled
into the libecasound.so shared library
- changed: to make ecasound relocatable, preset files are now
installed to standard data dir (defaults to
/usr/local/share/ecasound)
- changed: lot of source file name changes
- changed: ALSA support (libasound.so library) is now loaded
dynamically at runtime
- fixed: you had to have yodl installed to to install ecasound
man pages
150899 (v1.4.6r5) -** public release **-
- added: qtecasound - along with some other improvements,
waveform widget now uses cache files to store
wave statistics; for file "somefile.wav", cache
file "somefile.wav.ews" is used
- fixed: reading and writing aiff files works again;
some aiff files created with sox still seem to
cause trouble (might be a problem with
libaudiofile)
- fixed: qtecasound - a nasty mutex bug which caused ecasound
to crash if you tried to use a chainsetup which has
more inputs than chains
120899 (v1.4.5r4):
- added: qtecasound - dialogs for adding, removing and
attaching inputs and outputs
- added: support for null inputs/outputs
- added: effect status is now printed when exiting ecasound
(doesn't affect interactive mode)
- added: if OSS drivers for your soundcard don't support
trigger functions, you can disable these with
configure option "--disable-osstrigger"
- added: -ev effect (analyze sample data) now also tells
how much the analyzed signal can be amplified
without clipping
- added: debug level can now be set in iactive mode with
"debug level" command
- changed: qtecasound - shortcuts a, A and ctrl-a now do
the same thing; applies to all shortcuts
- fixed: adding a chain without a valid output resulted in
hangs when using multithreaded mixmode
- fixed: didn't compile with alsa-lib versions older than 0.3.1
- fixed: "ecasound -h" dumped core
010899 (v1.4.4r4)
- added: qtecasound - now asks for a name when adding chainsetups
- added: qtecasound - adding and deleting chains
- changed: some layout changes
290799 (v1.4.3r4)
- changed: if format supports it, outputs are now opened in
read-write mode; currently supported by .wav,
.cdr and .raw; when you use these as outputs, files
aren't truncated if they exist
- fixed: qtecasound - active chainsetup was always saved even
if some other chainsetup was selected
- fixed: qtecasound - crashed if you changed the active
chainsetup and you had a waveform window open
- fixed: qtecasound - crashed if tried to activate
a invalid chainsetup
- fixed: if you wrote to a output file, its length was
not changed (from ecasound's viewpoint)
270799 (v1.4.2r4)
- fixed: samplebuffer.h still tried to include <soundcard.h>,
which is both not necessary and a wrong place to
look for it; thanks to Torbjorn Tornkvist and
Xavier Hosxe for notifying me
- fixed: qtecasound - using multithreaded mixmode, changing
chainsetups on the fly caused a lot of problems
- fixed: qtecasound - shortcut keys didn't work with CLI
270799 (v1.4.1r4)
- added: qtecasound - chain widget now monitors effect
parameters
- added: qtecasound - support for double clicks and return
presses for various widgets
- added: qtecasound - some new features to the waveform widget
- changed: from now on, interactive mode isn't automatically
enabled, if a realtime input is specified
- changed: names of some functions (I'm trying to be careful
how I use 'new' and 'add', 'load' and 'open', etc
- fixed: qtecasound - waveform widget crashed qtecasound if
the analyzed file had less than 76800 samples
- fixed: if processing was completed and was restarted without
a rewind/setpos, ecasound crashed/hang
- fixed: raised-priority mode was sometimes enabled even
without the -r option
- fixed: qtecasound - when using multithreaded mixmode,
exiting sometimes resulted in core dump or segfault
250799 (v1.4.0r4)
- added: qtecasound - waveform widget; graphical representation
for input/output objects
- added: qtecasound - chain widget; view chain status
- added: qtecasound - chainsetup widget; status of input,
output and chain objects, enable/disable chains
- added: qtecasound - session-setup widget; load and save
chainsetups, create new ones, etc
- changed: can now be started without a valid chainsetup if
interactive mode is enabled
- fixed: *serious bug* if end of input was reached,
that input remained silent until ecasound was
restarted (has been broken since 1.3.0r3)
240799 (v1.3.3r4)
- added: -n option, sets chainsetup's name
230799 (v1.3.2r4)
- added: a new compressor - thanks for Viktor Endersz for
sending it to me and John S. Dyson for coding it;
it really works like a dream! (option -eca)
- fixed: some fixes to my old compressor (now that we
have a better one, this should be used only if
you really want brutal results :))
- fixed: due to some changes in ALSA libs, ecasound
wouldn't compile with ALSA versions >0.3.2;
haven't tested it, but should now work with both
new and old ALSA libs
200799 (v1.3.1r4) -** public release **-
- fixed: delay effect was broken; while fixing this I also
added a new surround mode, 2 = stereo-spread
- fixed: more bugs with ALSA and OSS input routines;
did some multitrack recording with both of them
and got suprisingly good results (it seems that
finding the optimal buffer size is the key to success)
190799 (v1.3.0r3)
- added: support for sessions and chainsetups; now you can
store the whole runtime setup to an ascii file and
load it back; the syntax used is exactly the
same as the command line syntax so editing these
saved chainsetup files is easy
- added: "-s[:]filename" command line option for loading
chainsetup files
- added: "load filename" and "save filename" commands to
the interactive-mode (for chainsetups)
- added: support for libaudiofile (SGI audiofile) library;
new file formats: .aiff, .au and .snd; (linking to
audiofile can be prevented with --disable-audiofile
option to the configure script)

- added: support for raw/headerless (.raw) input/output files
- added: support for using standard system input and output
streams (-i:stdin, -o:stdout)
- added: finished the man pages, all important options and
features should now be covered
- fixed: file name ending with a upper-case extension
wasn't recognised
- fixed: when using multithreaded mixmode with complex setups,
threads sometimes went out of sync causing strange
behaviour
- changed: size of sample buffer objects can now be changed
on-the-fly (output files are not aligned to
buffersize anymore) -> this makes ecasound more
usable as a format conversion tool
- changed: compressor wasn't working, decided to code
a new one (still experimental but works better
than the last one)
140799 (v1.2.3r3)
- added: support for .mp2 files
- fixed: still some bugs in selecting mixmode
- fixed: automatic stereo-mono conversion wasn't working
at all (as all chains are internally stereo, this
occured everytime you specified a mono output, even
if the input was mono, too)
130799 (v1.2.2r3)
- added: ALSA devices can now also be opened by specifying
the actual device name (/dev/snd/pcm...)
- changed: default output is now always attached to chain 'all'
- fixed: start/stop/forward/rewind with ALSA-output sometimes
resulted in loud crackle
- fixed: some bugs in the position slider of qtecasound
- fixed: 'noise-gate-mono' effect was rewritten as it didn't
seem to work very well
120799 (v1.2.1r3) -** public release **-
- added: 'make install' now creates /etc/ecasound directory
and copies all the configuration/preset files
to this directory (existing files/dirs are skipped)
- added: lots of crash-guards to command line parsing
- added: frequently-asked-questions file (both txt and html)
- added: new options to the configure script: --disable-alsa,
--disable-oss and --disable-qt
- fixed: bugs in mixmode multithreaded-iactive (crashed
pretty much everytime)
- fixed: estatus output was sometimes pretty messy
110799 (v1.2.0r2)
- added: support for ALSA input/output
- added: a lot of new documentation to the man pages
- added: new configurable options to ~/.ecasoundrc
(default-buffersize, default-to-interactive-mode,
default-to-raisepriority)
- added: finally implemented the 'help' command in
the interactive-mode; also added a prompt, which
should help a bit :)
- added: autoconf and automake additions; now qtecasound is
compiled only if qt library is found, OSS and
ALSA modules are compiled if the necessary
headers and libraries are available
- added: support for single-chain effect presets (-ps command
line option)
- fixed: bugs with OSS-input (device was sometimes closed
multiple times resulting in core dumps)
- fixed: auto-runmode used 'simple-iactive' mixmode
although iactive-mode wasn't set
- fixed: looping wasn't working properly
- fixed: -m option wasn't working
- removed: simple filter effect (not really useful)
- removed: 'Waiting for the processing thread'
messagebox (qtecasound)
100799 (v1.1.8r2)
- fixed: more synchronisation bugs
050799 (v1.1.6r2)
- added: rewrote the man-pages using Yodl; now they're
also available in HTML-format
- fixed: OSS-output module used a non-standard location
for soundcard.h (noticed by D.Phillips)
010799 (v1.1.5r2) -** public release **-
- tested: did some real recording and mixing work with this
version and after a few fixes, everything seems
to work ok
- added: now checks whether a chainop supports parameter
controlling or not
- added: a lot of new documentation (especially to
'Documentation/examples.html')
- fixed: chain 'all' wasn't working properly
- fixed: multitrack chain synchronization was broken; should
now work even with complex setups
- fixed: a serious bug in OSS-input: ecasound always threw
an "read-error" exception when trying to read from
OSS input
- fixed: analyze effect (-ev) output didn't work
300699 (v1.1.4r1) -** public release **-
- notice! first release; should be considered beta
- fixed: if mp3 files had white-spaces in their filenames,
filenames weren't interpreted correctly

- support for GNU autoconf and automake
- added some new command line shortcuts
- qtecasound: added a position slider widget (displays and

they will reappear in the "Chain Setup"
window (still under work)
160699 (v1.0.8r0)
- mp3 output support (using lame)
150699 (v1.0.7r0)
- fixed: waveform -output now works with all inputs
(for instance showing mp3 waveforms is now possible)
- routines for interfacing with mpg123 recoded;
a lot more stable than before
- qtecasound now uses the new qt library (v2.0beta2)
- support for various controllers (sine oscillator, MIDI
