In a debate on the value of 24b/192KHz consumer audio (using a good brick wall filter, minimal jitter), a friend posed the argument:
Nyquist never properly dealt with harmonics, which change sound pressures by riding a higher frequency on a lower frequency "carrier", increasing the propagation of the higher frequency and lending some extra punch to the lower frequency.
A post from ComputerAudioPhile.com poses the same:
So let's say you have a flute that produces a tone at 14kHz. It may then produce overtones or harmonics at 28kHz, 42kHz, etc. If say the 28kHz overtone is sufficiently strong, and you truncate at redbook sampling frequency (corresponding to a 22kHz signal), then you might get an artifact at 22kHz - (28-22kHz) = 16kHz, which, if you are young enough, might be audible.
My Nyquestions are: How does this actually work? Which papers should I read?
