grishgrigoryan / StreamMixer.ts
Created July 4, 2018 13:56
StreamMixer helps to play with MediaStream: Merge multiple streams into single one ( can be used with WebRtc to send multiple streams over a single WebRTC MediaConnection, or to switch streams without worrying about renegotiation)
export class StreamMixer {
streams: Array<{
id: string,
audioSource: any,
gainNode: any,
mediaStream: MediaStream
}>;
destination: any;
audioCtx: any;
