Value

A MediaStream representing the stream which contains the MediaStreamTrack serving as the source of audio for the node.

The user agent uses the first audio track it finds on the specified stream as the audio source for this node. However, there is no way to be certain which track that will be on multi-track streams. If the specific track matters to you, or you need to have access to the track itself, you should use a MediaStreamTrackAudioSourceNode instead.

Examples

const audioCtx = new window.AudioContext();
let options = {
  mediaStream: stream,
};

let source = new MediaStreamAudioSourceNode(audioCtx, options);
console.log(source.mediaStream);
