sorry not to respond earlier but I was engaged elsewhere.  Just
getting back to your report -- which is daunting....

Would you be so kind as to send me your test csd files?  It would give
be a head start in attacking them, and would be a great hep to me.
Kindly send offlist to this address, or at least a selection so I can
get back to this code, as it is 14 years since I looked closely.

that is complete

What does "values off by scale of 32768:" mean?

I will start with the example you sent (guiro)

John, no sweat on the delay, I understand we're all busy!

I'd be glad to send over my test.  I do most of my testing in Steven's
"Blue", because I just love the flexibility of the IDE, but would you
prefer it if I strip it down to a bare csd for simplicity?  I don't
mind either way, whatever will be best for you to troubleshoot with.

When I say off by a scale of 32768, I mean the "expected" value of 0-1
seems to explode the output, but if you divide it by 32768 you will
get a usable result.  This was only tested with 0dbfs=1, so the
results may be different when working without it.
