Live Audio Broadcaster

A server which allows audio publishers to broadcast to subscribers on a channel, using nothing more than a modern web browser.

It uses websockets for signalling & WebRTC for audio.

The designed use case is for live events where language translation is happening. A translator would act as a publisher and people wanting to hear the translation would be subscribers.
