If I set my AVAudioSession's category to AVAudioSessionCategoryAudioProcessing, I do not receive any interruption notifications regardless of what else I'm doing. (Locking the device, playing audio in another app, etc.) I understand why this is — AVAudioSessionCategoryAudioProcessing is for offline rendering with no input or output — but can this behavior be relied upon? Is it documented anywhere? Are there any situations in which a processing session will receive interruption notifications?
