# WebRTC Audio Publishing

This repository contains an application to publish [PulseAudio](https://www.freedesktop.org/wiki/Software/PulseAudio/) and
[JACK](https://jackaudio.org/) streams via [WebRTC](https://webrtc.org/) to a "room" on a server, which is the distributed
to one or more browser clients via [WebRTC](https://webrtc.org/).

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