DarkIce is a live audio streamer. It records audio from an audio interface (e.g. a sound card), encodes it, and sends it to a streaming server. DarkIce can record from OSS audio devices, ALSA audio devices, Solaris audio interfaces, and Jack sources. DarkIce can encode into MP3, MP2, Ogg Vorbis, and AAC formats, and can send the encoded stream to ShoutCast, IceCast 1.3.x and 2.x, and the Darwin Streaming Server.
IceGenerator is a direct stream generator for Icecast/Shoutcast servers. It streams MP3s to an Icecast/Shoutcast server without resampling it, saving CPU time. It features directory searches, MySQL/PGSQL support, M3U/PLS support, ID3 tags, META dynamic info, and a telnet interface.
The Slag project is a pattern-based audio sequencer that can currently be used as a simple drum box. It features real-time editing, optional JACK support with individual ports for tracks, volume settings for pads and tracks, a virtually unlimited number of tracks and patterns, the ability to link song parts together, and real-time audio file output.
