I thought CDs had a sampling rate of 44kHz? You need twice as many samples as the frequency you want to represent, after all (to make a wave you need both a positive anda negative sample in the same period). This is the essence of the Nyquist-Shannon a.k.a. the sampling theorem.

That's correct. CD's has a sample rate of 44.1kHz. And humans can hear above 20kHz, it's just that most don't.
