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

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

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