Examples

When processing is complete, you might want to use the oncomplete handler the prompt the user that the audio can now be played, and enable the play button:

let offlineAudioCtx = new OfflineAudioContext();

offlineAudioCtx.addEventListener('complete', () => {
  console.log('Offline audio processing now complete');
  showModalDialog('Song processed and ready to play');
  playBtn.disabled = false;
})

You can also set up the event handler using the OfflineAudioContext.oncomplete property:

let offlineAudioCtx = new OfflineAudioContext();

offlineAudioCtx.oncomplete = function() {
  console.log('Offline audio processing now complete');
  showModalDialog('Song processed and ready to play');
  playBtn.disabled = false;
}
