No it's not, you're confusing it with how many bits are used.
Once you are above the Nyquist frequency you can perfectly represent the sample. Any more frequency does absolutely nothing.
But the number of bits of resolution that's what actually determines how perfectly the digital wave form matches the original.
- fb03 7y agoah, thank you! yes. every bit adds about 6db of headroom right?
- ars 7y agoYes, that's correct. Wikipedia claims that more than 21 bits is pointless for actual playback since there are no circuits that can be that accurate (quiet). But more bit depth can help with mixing headroom - but you don't need a lot. "24 bits is enough for anyone." © :)
- guggle 7y agoYes, for playback. For some people there's a lot of confusion about bit depth since it can represent a range of integers (like how the data is stored in a wav file or what dacs process) or a range of floats. Internally, audio apps typically represent signals as sequences of 32bit floats between -1 and +1.
