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.

OfflineAudioContext.resume()

The resume() method of the OfflineAudioContext interface resumes the progression of time in an audio context that has been suspended. The promise resolves immediately because the OfflineAudioContext does not require the audio hardware. If the context is not currently suspended or the rendering has not started, the promise is rejected with InvalidStateError.

OfflineAudioContext.startRendering()

The startRendering() method of the OfflineAudioContext Interface starts rendering the audio graph, taking into account the current connections and the current scheduled changes.
API Method OfflineAudioContext Reference startRendering Web Audio API

suspend

The suspend() method of the OfflineAudioContext interface schedules a suspension of the time progression in the audio context at the specified time and returns a promise. This is generally useful at the time of manipulating the audio graph synchronously on OfflineAudioContext.

OscillatorNode.onended

The onended property of the OscillatorNode interface is used to set the event handler for the ended event, which fires when the tone has stopped playing.

OscillatorNode.setPeriodicWave()

The setPeriodicWave() method of the OscillatorNode interface is used to point to a PeriodicWave defining a periodic waveform that can be used to shape the oscillator's output, when type = "custom" is used.
