<audio>: The Embed Audio element - HTML: Hypertext Markup Language
detecting addition and removal of tracks you can detect when tracks are added to and removed from an <audio> element using the addtrack and
removetrack events.
... for example, to detect when audio tracks are added to or removed from an <audio> element, you can use code like this: var elem = document.queryselector("audio"); elem.audiotracklist.onaddtrack = function(event) { trackeditor.addtrack(event.track); }; elem.audiotracklist.on
removetrack = function(event) { trackeditor.
removetrack(event.track); }; this code watches for audio tracks to be added to and removed from the element, and calls a hypothetical function on a track editor to register and remove the track from the editor's list of available tracks.
... you can also use addeventlistener() to listen for the addtrack and
removetrack events.
