WASP - WebRTC Audio Streaming Publisher

WASP is an audio streaming application which allows you to publish PulseAudio and JACK streams via WebRTC to a "room" on a server, which is the distributed to one or more browser clients via WebRTC.

The server application can be found in the server directory, the publisher application in the publisher directory. Common code between the two is shared via common.
