acast is a program for webcasting audio from your sound device to a variety of different streaming servers Its features include:

- can stream the audio in Ogg Vorbis (http://www.xiph.org) to Icecast 2.x (http://www.icecast.org) servers and in mp3 to all the servers mentioned above
- the webcast stream can also be recorded to disk
- an extra higher quality stream can also be recorded to disk
- wav files ready to be burnt onto cd can also be recorded to disk
- GTK+2 interface as well as a console interface (useful for remote starting of streams)
- All the streams (webcast and recording ones) can be individually started and stopped dynamically while the streams are running
- the recording filenames can also be changed, thus allowing a conference to have separate files for each speaker, without interrupting the broadcast
- same stream can be webcast to multiple servers, by adding relays
- acast uses GStreamer (http://gstreamer.freedesktop.org/) and it is this that makes acast possible.
