Audio Streaming with WebRTC

What does this do?

This demonstrates an audio streaming using WebRTC between the two browsers. Instead of using microphones, sender side browser reads a MP3 file, then streams it out to the receiver using WebRTC, while the receiver plays the audio stream in real-time.

How to run?

Check out the repo, cd into the root folder, then:

npm install
npm start

Browser to browser

HTTP server with signaling service (socket.io) should be running at URL: http://0.0.0.0:8080. Open your browser at the URL, then follow the further instruction.

Browser to pion/webrtc

Open your browser at the URL (same as above), then click "sender tab" page only.

cd into pion folder, then:

go build
./pion --use-stun
