nyquist

I tried an experiment. I generated a sinusoidal signal, the frequency of which ranged smoothly from 11999Hz to 12001Hz over 300 seconds. The sampling rate was 48000Hz. The bit depth is 32. I did this inside the Izotope program. I also did the same by connecting the balanced output of my S.M.S.L...

Got into a discussion on another forum. Trying to see if a user‘s claims have any theoretical merit. So, Nyquist states that if you sample >2x the frequency range you want, it can reproduce that range perfectly (with quantization noise). However, what if there was a super short transient (say...
