Guessswork algorithms not recovered data

the only way a CD player could ever possibly output anything approaching a smooth sine wave at 10 kHz, let alone 19kHz is if it had an internal algorithm that GUESSES that the signal should be sine rather than relying on the supplied data avaialble.

I'd lay bets that they are set up to output smooth sine waves at the upper frequencies based upon repeating intervals of sampling that give clues to spot frequencies and that if you feed them with a triangular wave, a sawtooth wave or a pentagonal wave they'll still output a very beautiful sine that you can John Elison can display on your CRO screens to prove that there's full recovery of the high level signal.

Digital boys, try this on for size: You cannot recover data that has not been recorded. It's that simple. to argue otherwise is futile.
