I have a BASIC program sitting around that requantizes sounds into 11
kHz from 1.0-44.1 kHz.  It's dreadfully slow, though (it took 12 hours
to do about half a meg sampled at 20.0 kHz).  Once it's in assembly,
though (how long ago did I say I'd convert it to assembly? :-) ), it
can go into SoftDAC.

The odds of playing 22 kHz sounds directly is anywhere from slim to
none.  The timing for 11 kHz is tight enough on a system with a 1-MHz
clock.  (There is the possibility, though, once I get my RocketChip,
that I could play with the program to deliver faster speeds or more
bits in a sample.)
