The onended event handler of the AudioBufferSourceNode contains the callback associated with the ended event: this allows you to run code in response to the audio track finishing playback.

Note: The onended handler won't have any effect if the loop property is set to true, as the audio won't stop playing. To see the effect in this case you'd have to use AudioBufferSourceNode.stop().


var source = audioCtx.createBufferSource();
source.onended = function() { ... };


source.onended = function() {
  console.log('Your audio has finished playing');
