The close() method of the AudioContext Interface closes the audio context, releasing any system audio resources that it uses.

Closed contexts cannot have new nodes created, but can decode audio data, create buffers, etc.

This function does not automatically release all AudioContext-created objects, unless other references have been released as well; however, it will forcibly release any system audio resources that might prevent additional AudioContexts from being created and used, suspend the progression of audio time in the audio context, and stop processing audio data. The returned Promise resolves when all AudioContext-creation-blocking resources have been released. This method throws an INVALID_STATE_ERR exception if called on an OfflineAudioContext.

Syntax

var audioCtx = new AudioContext();
audioCtx.close().then(function() { ... });
await audioCtx.close();

Returns

A Promise that resolves with void.

Example

The following snippet is taken from our AudioContext states demo (see it running live.) When the stop button is clicked, close() is called. When the promise resolves, the example is reset to its beginning state.

stopBtn.onclick = function() {
  audioCtx.close().then(function() {
    startBtn.removeAttribute('disabled');
    susresBtn.setAttribute('disabled', 'disabled');
    stopBtn.setAttribute('disabled', 'disabled');
  });
}
