MAST - Multicast Audio Streaming Toolkit

MAST is set of audio streaming tools using RTP over IPv4 and IPv6 Multicast/Unicast.

Unlike VAT and RAT, which are designed primerily for audio conferencing, MAST is designed to be used for audio distribution and broadcast. It is currently limited to recieving a single audio source, unlike RAT which can mix serveral sources.

It supports many of the audio payload types in the Audio-visual Profile (RTP/AVP).

MAST is licenced under the GNU General Public License.

For more information please read the README, INSTALL and ChangeLog files. To build MAST, you will need the CVS version of oRTP, which is available here as a tarball for convenience.
