<<There is definitely advantage to post-processing in 24bit, but not=A0

While it's true there are very few circumstances in the real world=A0
which provide even a full 16 bit dynamic range I'm not sure adding 8=A0
extra empty bits at the bottom of the word for greater post processing=A0
resolution actually accomplishes anything. Current DAWs do their=A0
internal math at 32 bit floating point (or 48 bit fixed point in=A0
ProTools) so the extra empty bits are already being added within the=A0
DAW. When there is actual audio contained in the lowest 8 bits there=A0
will be an advantage when the numbers are rounded during any internal=A0
DAW processing, but I don't see how simply adding zeroes provides that=A0
same resolution benefit. Even though physics limits the maximum signal=A0
to noise ratio possible within any analog circuit preceding or=A0
following the AD-DA conversion to about the equivalent of 21 bits, I=A0
think I'd rather have the least significant 8 bits contain noise,=A0
since the ear/brain is capable of hearing coherent audio at a lower=A0
level than the uncorrelated noise.
