That equation is so wrong.
filesize(192kHz + 24bit) = 6 * filesize(48kHz + 16bit)
It also only applies directly to raw audio like pcm. Once you encode it (to, say, flac) some of that size increase could disappear depending on the waveform.
I don't know how mp3 is defined for higher dynamic range, but I know frequency range/sampling rate doesn't matter, because a 128kbps mp3 is 128kbps whether the frequency cutoff is 14kHz or 20kHz. Isn't a 192kbps mp3 from a 16/48 master the same size as a 192kbps mp3 from a 24/192 master?
- ygra 13y agoAll this isn't about MP3, but FLAC which is lossless, so even for the compressed version the same ratios should approximately hold.
- harshreality 13y agoApproximately? Either it does or it doesn't. What I'm thinking is that a 4x increase in sampling rate doesn't necessarily lead to a 4x increase in waveform complexity except for certain types of random noise. With the references to 192kbps and mistakes, it wasn't clear what parent was talking about.
