MediaStreamTrack: muted property

Limited availability

This feature is not Baseline because it does not work in some of the most widely-used browsers.

The muted read-only property of the MediaStreamTrack interface returns a boolean value indicating whether or not the track is currently unable to provide media output.

Note: To implement a way for users to mute and unmute a track, use the enabled property. When a track is disabled by setting enabled to false, it generates only empty frames (audio frames in which every sample is 0, or video frames in which every pixel is black).

Value

A boolean which is true if the track is currently muted, or false if the track is currently unmuted.

Note: When possible, avoid polling muted to monitor the track's muting status. Instead, add event listeners for the mute and unmute events.

Examples

This example counts the number of tracks in an array of MediaStreamTrack objects which are currently muted.

let mutedCount = 0;

trackList.forEach((track) => {
  if (track.muted) {
    mutedCount += 1;
  }
});
