Broadcasting live with MIXXX or B.U.T.T.
This how to is intended for DJs using BUTT or MIXXX to stream to their LibreTime server with an external USB audio card setup to route a mixer and sound.
Live shows with MIXXX
Mixxx is a cross-platform Open Source application for DJs, available here.
Installed on a desktop or laptop computer, Mixxx complements your LibreTime server to provide a complete system for both live and scheduled broadcasting. Although Mixxx has many features designed for dance music DJs that require beat matching and pitch independent time stretching, the program can be used for any kind of manually triggered broadcast playout, including live speech shows such as news or current affairs.
Mixxx supports a wide variety of popular hardware control surfaces, which can be connected to your computer using a USB cable. A control surface might replace or augment an analogue mixer in your studio, depending on your live mixing and playout requirements.
Mixxx 1.9.0 or later includes a live streaming client which, like LibreTime, is compatible with the Icecast and SHOUTcast media servers. This feature can also be used to stream from Mixxx directly into LibreTime, using either the Show Source or Master Source.
To configure Mixxx for streaming into LibreTime, click Options, Preferences, then Live Broadcasting on the main Mixxx menu. For server Type, select the default of Icecast 2. For Host, Mount, Port, Login and Password, use the Input Stream Settings configured in the LibreTime Streams page, on LibreTime's System menu. See stream settings for remote input connection details.
