MediaStreamAudioDestinationNode: stream property

Baseline Widely available

This feature is well established and works across many devices and browser versions. It’s been available across browsers since April 2021.

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.

Value

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

Examples

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