Quote ken long:
I love how these threads on SR always end up advising the OPs that there are many other factors to consider when recording than the converters.
If one calmly re-reads the OP, one can surmise that he has asked a question about the theory and science behind sampling. Had he had asked "will my recordings get better using higher a higher SR?" then we could probably advise on all other factors. As it stands, he's asked a theoretical question about the science involved.
Yup it was a simple question, perhaps too simple, but the answers are nonetheless interesting - certainly much more to this than meets the eye. Mark G's post had me suckered right up until the words "total vacuum".
If you think that post was bizarre check out the comments Rupert Neve made regarding this subject. He says 24-bit is fine except 192 kHz is required as the frequency range has to be free (of distortion/noise) up to about 75 kHz. Not doing this is very dangerous. Why? Because the Japanese showed (bad) distortion/noise above 20 kHz makes the brain produce 'electric radiations' associated with (brain) discomfort, frustration, and even anger. Therefore Neve wonders whether we cannot blame the CD for some of our social problems?
So, is it true that the frequency range ought to be considered up to 75 kHz? Is it possible that mp3s could cause bit-rage? Is this bloke actually on to something, or is he off his swede?
