Sep 20, 2019 at 8:32 | comment | added | Hobbes | that's not the same though. Audio reproduction is governed by the Shannon-Nyquist sampling theorem, and you can build an AD-DA chain that perfectly reproduces the original signal. For visual media, we're far away from being able to do that because you'd have to scan individual atoms to get a perfect reproduction. | |
Sep 20, 2019 at 8:14 | comment | added | TimK | @Hobbes although that is true I would say that it is the same as asking what the equivalent pixel density is of an original Van Gogh painting is. You can compare the aspect ratio and canvas size but you are not going to calculate ppi. | |
Sep 20, 2019 at 7:10 | comment | added | Hobbes | That's incorrect. There is a fairly simple way to compare the two: the sample rate directly translates to the bandwidth of the recording (44 kHz sampling = 20 kHz bandwidth), and the bit depth tells you the SNR (1 bit = 6 dB of SNR, if we ignore noise shaping). | |
