/Web APIs


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.
