OfflineAudioCompletionEvent

Baseline Widely available

This feature is well established and works across many devices and browser versions. It’s been available across browsers since July 2015.

See full compatibility

The Web Audio API OfflineAudioCompletionEvent interface represents events that occur when the processing of an OfflineAudioContext is terminated. The complete event uses this interface.

Note: This interface is marked as deprecated; it is still supported for legacy reasons, but it will soon be superseded when the promise version of OfflineAudioContext.startRendering is supported in browsers, which will no longer need it.
