In Reply to: "the huge dynamic range of many LPs" - Which ones? [nt] posted by Chris from Lafayette on September 29, 2017 at 10:19:01:
Hi Chris,
It turns out that due to the RIAA pre-emphasis/de-emphasis process that LPs can reach a dynamic range of over 90 dB in the mid-band - where our hearing is the most sensitive. Add to that the fact that the marvelously sophisticated human ear/brain can hear between 20 and 30 dB below the noise floor means that 24-bit digital is really a good idea, and pretty much necessary to ensure that one has *for-sure* captured everything that is on the LP.
Granted, a 16-bit transfer will usually suffice for many recordings, but with today's technology and low cost of storage, there is really no reason not to go to 24 bits. On the other hand it is extremely difficult to make a case for 32 bits - except in a DAW where one wants to maintain 24-bit resolution when all of the effects are applied. That is why all modern DAWs use 24 bits - to ensure that the final product has at least 16 bits of resolution.
Hope this helps,
Charles Hansen
