Re: harmonic vs. inharmonic sounds (one last time)
Dear Al and others,

I have framed the explanation in terms of repetition rate because it
was easy to do, but it might not be correct. For example a "harmonic
sieve" or template, might derive pitch.
We have detailed data on pitch shift caused by the medical drug
carbamazepine. These data exclude the possibility of pitch extraction
via a ' "harmonic sieve" or template '.
These data are compatible, however, with the concept of pitch extraction via
tuned periodicity detectors.
