Default 16 bit vs 24 bit, 44.1khz vs 48 khz <-- please explain

So, if you're recording, say, someone's vocals at both 16 and 24
bits, and the peaks are at -6dB to 0dB FS, does the 24 bit recording
represent more accurately the signal in that region than the 16-bit
version?


The extra 8 bits give you 48 db more dynamic range between EVERY
sample. Between sample value = 0 and sample value = 1 they give you
an extra 48 db on the bottom end.

On the loud end, 16 bit max value is 32767 (0x7FFF), second value is
32766 (0x7FFE). That equates to 24 bit values 8388352 (0x7FFF00) and
8388096 (0x7FFE00), a difference of 256 values, the equivalent of 48
dB dynamic range.


Agreed. I figured that out a few hours after I posted, but I was nowhere
near a computer with internet access. I then started wondering who would be
the first to catch my error.
