Naudio - Disposing WaveIn / WaveOut

Is it safe to dispose WaveIn and WaveOut right after stopping them, and not in the event handlers of WaveIn.RecordingStopped and WaveOut.PlaybackStopped? Like this:

MyWaveIn.StopRecording();
MyWaveIn.Dispose();
MyWaveIn = null;

And:

MyWaveOut.Stop();
MyWaveOut.Dispose();
MyWaveOut = null;

If WaveIn / WaveOut stopped due to an error, or if the playback stopped because the file being played reach its end, I will dispose them in the event handlers. I'm asking just about the situation where I stop them explicitly.

Solution

  • I generally recommend disposing in the PlaybackStopped event handler, but most soundcard drivers seem perfectly happy with you disposing while playback or recording is still in progress (under the hood you're just calling the waveOutClose or waveInClose windows API).
