CD frequency is limited by the sampling frequency, which must be at least 2x the highest audio frequency.
Actually, double the frequency of any harmonic that wants to be included. What reminds me, that one trick of the trade was to artificially add harmonics that were not in the recording (because it is impossible to mechanically record and reproduce them), so that sound looked more "natural". It is a very old trick: the old phone handsets resonated at certain frequencies that the line could not transmit, to that voice seemed "natural". -- Cheers / Saludos, Carlos E. R.
