Web/API/OfflineAudioCompletionEvent

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

Properties

Also inherits properties from its parent, Event.

OfflineAudioCompletionEvent.renderedBuffer Read only: An AudioBuffer containing the result of processing an OfflineAudioContext.

Methods
