Raimund,
What did the noise floor consist of? Is this level the added dither? You can
get total silence below 15 bits +1 without dither but the quantising noise
is then bad. The output is a 16 bit uncompressed file, even if 18 bits were
used in quantising it, so what is the effective final dither level? 108dBs
is a dynamic range of 18 bits and with a parity bit, this is 19 bit A to D.
Are the Sony figures about adding two bits worth of dynamic range taking
dither into account, or is this an engineering exercise in numbers? I can't
see how you can get 18 bits into a 16 bit WAV pint pot. The dynamic range
from 1 bit (square wave) to 15 bits digital is 84dBs.
If you or anyone has a WAV file of "silence" on the two settings it may be
interesting to compare them.
