AudioContext: resume() method

The resume() method of the AudioContext interface resumes the progression of time in an audio context that has previously been suspended.

This method will cause an INVALID_STATE_ERR exception to be thrown if called on an OfflineAudioContext.

Syntax

js

resume()

Parameters

None.

Return value

A Promise that resolves when the context has resumed. The promise is rejected if the context has already been closed.

Examples

The following snippet is taken from our AudioContext states demo (see it running live.) When the suspend/resume button is clicked, the AudioContext.state is queried — if it is running, suspend() is called; if it is suspended, resume() is called. In each case, the text label of the button is updated as appropriate once the promise resolves.

js

susresBtn.onclick = () => {
  if (audioCtx.state === "running") {
    audioCtx.suspend().then(() => {
      susresBtn.textContent = "Resume context";
    });
  } else if (audioCtx.state === "suspended") {
    audioCtx.resume().then(() => {
      susresBtn.textContent = "Suspend context";
    });
  }
};
