rabbit!jj's comments about dither being a way to improve signal-to-noise
ratios are quite true - there have been some interesting articles in the
"IEEE Communications Magazine" and "IEEE Transactions on Communications" about
it, mostly with an eye to military applications.  Unfortunately, most
digital recorder designs, like rabbit!jj mentions, don't use it.
The real question here is, how much improvement can dither provide (my guess
from what I've read about it is several dB, does anyone have a more exact
answer?)
