babelcast

README

Babelcast

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.

Building

Download a precompiled binary or build it yourself.

Usage

Usage of ./babelcast:
  -debug
        enable debug log
  -port int
        listen on this port (default 8080)

Then point your web browser to http://localhost:8080/

If the PUBLISHER_PASSWORD environment variable is set, then publishers will be required to enter the password before they can connect.

TLS

Except when testing against localhost, web browsers required that TLS (https) be in use any time media devices (e.g. microphone) are in use. You should put babelcast behind a reverse proxy that can provide SSL certificates e.g. Caddy.

See this Stackoverflow post for more information.
