@Brunk, (and anyone who might misinterpret those graphs)
The graph on the left is fundamentals only.
For example, cymbals, if fundamentals go up to 16Khz, there will be harmonics at 32kHz, at 64kHz, at 128kHz etc, almost to infinity. That's how sound works in real life, that's what we hear when someone bashes a cymbal. Analog.
Hence the importance of recording in analog, mixing in analog, mastering in analog, and if it has to be converted to digital at the end of the chain, it's important to keep as much high end (natural harmonics) in there, to keep the 'real sounding sound'. Sampling at 96kHz will allow frequencies up to 48kHz to remain relatively intact. That will sound "pretty realistic". Sampling at 192kHz will allow frequencies up to 96kHz to remain relatively intact. So those cymbals will sound realistic.
That's how it works.
If you sample at 44.1kHz, every harmonic over 22.05kHz will be missing, so cymbals, violin, trumpet etc, will be missing harmonics on into infinity.
It also affects how we perceive the lower harmonics, as Bob Katz explains in his book (see earlier in this thread).
