It seems that the application of Nyquist to audio is a bit of a myth. Perhaps more of a marketing scam to get engineers who didn't want to do their math on board with the idea of digital audio.

If you look into test equipment, you will find that the test equipment manufacturers use a more stringent standard: they scan at 10X the highest frequency to be measured/displayed. That is because they want waveform accuracy, which Nyquist does not give you.

If you look into the better digital recorders nowadays, you will see a lot of them using higher scan frequencies as well. My Alesis Masterlink can scan at 88.2KHz, allowing for a much better sounding CD as a result.

What you have to get is that if Nyquist were real, there would be no sonic improvement by using more advanced scan techniques. Occam's Razor tells us that in the face of this, Nyquist's application to digital audio is phony.
