Remarks

The QuantumProcessed event is asynchronous, which means that you can update the properties and state of the AudioGraph and individual audio nodes in the handler for this event. However, because this event is asynchronous and raised only after the audio engine has completed processing, it is not raised on a regular cadence and it should not be used for synchronized processing of audio data such as that obtained from the AudioFrameOutputNode.GetFrame method. Instead, it is recommended that you use the QuantumStarted event for synchronized audio processing.
