OK, now _I'm_ the one who's confused. I thought that what Ulysses wrote
above was pretty well established and non-controversial, and furthermore
that you (Chris) were already in agreement with it (based upon your post
back to me just a few minutes earlier). So what exactly is
contradictory here? What does Watkinson say that seems to counter the
above?

Watkinson's The Art of Digital Video, 2nd ed. pg. 143-144 (sorry,
don't have The Art of Digital Audio handy):
" the principles of analog and digital dither are identical; the
processes simply take place in different domains using two's
complement numbers which are rounded or voltages which are quantized
as appropriate. In fact quantization of an analog dithered
waveform is identical to the hypothetical case of rounding after
bipolar digital dither where the number of bits to be removed is
infinite, and remains identical for practical purposes when as few
as 8 bits are to be removed. Analog dither may actually be generated
from bipolar digital dither (which is no more than random numbers
with certain properties) using a DAC."

Hopefully, I'll be shown to have misunderstood the above, and can
go back to my comfortable but fuzzy understanding of things before
this blasted thread started. Ignorance was bliss, and I'm too old
to study.

Thanks!
