- rightbyte 3y agoIf you got an ideal filter maybe. Having margin to half the sampling frequency helps filter design. Then again, the frequency response of the loud speaker is not flat so I dunno if the sampling filter cutoff frequency matters.
- bandrami 3y agoThe real rabbit hole is when you start looking into the frequency response of your eardrums
- rightbyte 3y agoSure but I guess the goal is for the replayed sound to sound the same as the original would. According to Wiki the absolute max an amazing(?) ear can hear is 28kHz. You can maybe hear aliasing of higher frequencies too? I can't hear any difference between 44.1kHz and faster sampling, but we can't refute it on purely theoretical ground.
- bandrami 3y agoThat's not what I'm getting at. For most purposes the 22KHz limit is a hard one. What I mean is that the eardrums do not have a linear response at any frequency.
- ilyt 3y agoYeah but you can keep source material at 44.1k and oversample before the DAC. And 24 bit is nice purely because you can regulate volume in software without losing fidelity (if DAC is good enough). But again, no such requirement on source, just the processing pipeline
