Lossy compression reduces entropy, I'd expect fewer repeats and more of what looks like random data in any compression worth its salt. Thomas also mentioned AAC, not PCM. I agree on the silence, but it would come up as smaller packets, not repeated packets, IMO. And then we're back to timing analysis of speech.

Um, so, just to make sure I understand you, you're implying that lossy compression is not worth its salt? Because you will surely have more repeats in a lower entropy space.
