PCM, DSD - Trying to get my head round some basics 2017-04-23 10:21:17 I've recently revived an interest in music/equipment, but am only slowly putting the pieces together regarding the PCM/DSD discussions.My main query is regarding the value of a sampled bit. There are plenty of references that state things like '24 bits has a higher dynamic range than 16 bits'. Why does a bit sample always have to have the same amplitude value? Why can't you expand (say) 90dB into 24 bits instead of 16 bits, and get higher resolution?With DSD, is a 0/1 bit switch the same amplitude as one of the 65535 16 bit bits?DSD is quoted as having a better impulse response than PCM. Surely though (at least in theory) PCM can go from 0-65535 in one sample, whereas DSD would take 65535 samples to do the same? So DSD would have to be at 65535 times the sample rate to get the same response?Obviously in practice you wouldn't get these extreme values, but what is the reality of the speed of a transient? DSD would only be good with transients of low amplitude.Or have I got everything completely bass-ackwards?
