You’d think, but you still need a megahertz-resolution DSP to emulate some signal chains closely, due to phasing and reflected harmonics: https://youtu.be/GjtE

Although to be fair, most of the time “liking the sound” is indeed just due to quirks of the analog implementations, like eq cramping. Those differences were emulated long ago, and producers often do reach for a “colored” emulation instead of the “ideal” digital filter.

- ilyt 4y agoFunnily enough, same problem with trying to emulate CRT on LCDs
- kazinator 4y agoIn terms of audio, you only have to emulate what can actually be heard. Ears don't hear phase effects that require megahertz resolution. (Ears hear only binaural phase effects. If the phase doesn't change when you turn your head, it is not relevant.)
- progrus 4y agoCheck out the video. Harmonics above Nyquist can still reflect back into the audible range. About phasing issues, it is not usually the path-difference between your two ears, but harmonic interference due to mixing the phased signals, which cancels out desirable frequencies. Although I do have another excellent Dan Worrall video for you, about the ears thing: https://youtu.be/uZ9WQDojQt8 https://youtu.be/uZ9WQDojQt8
