Default compound extensions are used by the PROS tasks when no extension is given for the output file name. Most PROS tasks allow the output file name to be defaulted, with the convention that the output file name will be composed of the input `root' name, plus the default extension specific to the task. ...

... Unlike clients such as Shout and IceDJ this permits the broadcast of live audio, rather than prerecorded mp3's. LiveIce was developed after the appearance of IceCast to provide the Real Time streaming functionality which makes it a viable solution for broadcasting. It is based on the guts of 2 of my previous works - Mp3Serv, the first mp3 broadcasting system & Mp3Mixer, a toy which allows the user to 'Mix' with mp3 streams. ... LiveIce XMMS sourcecode is available here . ...
