I have a different clock problem...when using bucket brigade
devices (BBDs), the clock frequency is twice the sampling
frequency.  Is there a way to make the clock frequency
four or eight times the sampling frequency?

I was thinking that a counter might do it.  To get the
length of delay I want, the clock runs under 20KHz, so
I can hear it through the BBD output.  Now I'm using
a pair of RC low-pass filters, which gets rid of the
clock sound, but also most of the high end.  The active
filters I tried weren't any better.  I looked at 
active filter chips (CCDs, I think), but they were
$25 each, or so.  I'd pay up to $5-10 for one.
