{{APIRef("HTML DOM")}}

The read-only {{domxref("AudioTrack")}} property label returns a string specifying the audio track's human-readable label, if one is available; otherwise, it returns an empty string.

Value

A string specifying the track's human-readable label, if one is available in the track metadata. Otherwise, an empty string ("") is returned.

For example, a track whose {{domxref("AudioTrack.kind", "kind")}} is "commentary" might have a label such as "Commentary with director Mark Markmarkimark and star Donna Donnalidon".

Examples

This example returns an array of track kinds and labels for potential use in a user interface to select audio tracks for a specified media element. The list is filtered to only allow certain track kinds through.

function getTrackList(el) {
  const trackList = [];
  const wantedKinds = [
    "main",
    "alternative",
    "main-desc",
    "translation",
    "commentary",
  ];

  el.audioTracks.forEach((track) => {
    if (wantedKinds.includes(track.kind)) {
      trackList.push({
        id: track.id,
        kind: track.kind,
        label: track.label,
      });
    }
  });
  return trackList;
}

The resulting trackList contains an array of audio tracks whose kind is one of those in the array wantedKinds, with each entry providing the track's {{domxref("AudioTrack.id", "id")}}, {{domxref("AudioTrack.kind", "kind")}}, and {{domxref("AudioTrack.label", "label")}}.
