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. Chaloupka, V., Mitchell, S., Muirhead, R., 1992.
