MediaStreamAudioDestinationNode.stream

The stream property of the AudioContext interface represents a MediaStream containing a single audio MediaStreamTrack with the same number of channels as the node itself.

You can use this property to get a stream out of the audio graph and feed it into another construct, such as a Media Recorder.

Syntax

var audioCtx = new AudioContext();
var destination = audioCtx.createMediaStreamDestination();
var myStream = destination.stream;

Value

A MediaStream containing a single audio track. The audio track is a MediaStreamTrack whose kind is audio.

Example

See AudioContext.createMediaStreamDestination() for example code that creates a MediaStreamAudioDestinationNode and uses its stream property as a source for audio to be recorded.
