No argument there. I'm just saying that if you did, that shouldn't cause
a problem for deemphasis software. I mean, I would hope the (plugin?)
implementer(s) would know the dynamic range requirements of the
algorithm and resample/requantize if necessary.
I was suggesting that there may be benefit to digitizing at 24 bits when
in fact you have far more noise than signal going into the converter. Do
a sharp FIR high-pass at 18 Hz and you still have plenty of bits of signal
left if you are lucky.
