44100 is not a bad sampling rate, but it necessitates very sharp aliasing filters,
When you're talking about recording, sure, but in terms of storage and playback, we solved that problem 20 years ago with oversampling.
- Derbasti 15y agoYou will still need a aliasing filter that cuts off between, say, 18 and 22.5 kHz to avoid aliasing noise. That is one sharp filter no matter how you look at it. You can use a high quality, long, linear-phase FIR filter, but you can't cheat physics: sharp filters necesserily introduce distortion, and such a sharp filter so close to the hearing threshold does not go unnoticed.
- sjwright 15y agoI don't see how a sharp filter could be needed if the DAC is oversampling.
