Realtime/Working WebRTC Experiments

1. It is a repository of uniquely experimented WebRTC demos; written by Muaz Khan!
2. No special requirement! Just Chrome (for desktop and android) or Firefox!
3. These demos/experiments are entirely client-side; i.e. no server installation needed!

How to record audio using RecordRTC?

<script src="https://www.webrtc-experiment.com/RecordRTC.js"></script>

var recorder = RecordRTC(mediaStream);

recorder.startRecording();
recorder.stopRecording(function(audioURL) {
   window.open(audioURL);
});

// get blob
formData.append( 'blob', recorder.getBlob() );

// get DataURL
window.open( recorder.getDataURL() );

RTCMultiConnection.js / A library for all WebRTC APIs

<script src="https://www.webrtc-experiment.com/RTCMultiConnection-v1.4.js"> </script>
