Anything above 20 kHz of your sound is for dogs and bats!
Even the 2 kHz difference between 44.1 and 48 kHz do make a difference. Its the analog filters you need before your DAC for recording. On 44100 hz the filter needs to cut between 20 and 22.05 kHz by maybe 50dB, which creates all kinds of ripple in the audible area. On 48 kHz it needs to be only half as steep. On 96 kHz a simple filter would be sufficient already… (a 24 dB per octave filter would cut it already by 48 dB, as it may alias into the inaudible area between 20 kHz and nyquist. That gives you about 2 octaves range for the filter. Whereas the range between 20 and Nyquist at 48 kHz is a much smaller intervall…
I would always prefer to record on 96 kHz, the difference is pretty audible even on cheap audio interfaces. Later for processing and mixing it depends on your non-linear fx like saturation. If they have internal oversampling you are fine to run your session in 48 kHz like I do mostly.
Sample rate conversion is pretty good nowadays, and as Edgar said downsampling is better than the other way around…
Alright, I guess this is a major consideration for every acoustic musician, but I’m mostly ITB using plugins and softsynths.
According to what you say I would benefit from higher SR if I have my mastering done on analog gear right ? Is 48khz a good choice in the case ? I wonder how far goes the audible difference.
