MediaStreamAudioSourceNode: mediaStream property
Baseline
Widely available
This feature is well established and works across many devices and browser versions. It’s been available across browsers since July 2020.
The MediaStreamAudioSourceNode interface's
read-only mediaStream property indicates the
MediaStream that contains the audio track from which the node is
receiving audio.
This stream was specified when the node was first created,
either using the MediaStreamAudioSourceNode()
constructor or the AudioContext.createMediaStreamSource() method.
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);
