A Question of Bit Depth. 2003-08-10 15:33:09 Bit depth and dynamic range in DB. (excluding the effects of dithering) I have heard from various sources that :-08 bit = 048 db16 bit = 096 db24 bit = 144 dbI have also heard from various sources that each "bit" equals an increase in dynamic range by 6 db. This makes perfect sense in relation to the bit depths above. But what about an audio file in PCM format that is 1 bit? I cannot understand how 6 db of dynamic range could be represented in 1 bit. (or 2 bits equalling 12 db)Does this mean that "each bit equalling 6 db of resolution" is true or false?
