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 ⁨October 2018⁩.

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.

Examples

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