Mono pitcher (filter with harmonically related resonant peaks) algorithm
with a chorus or flanger
Allocation Units: 2 (each)
The mono pitcher algorithm applies a filter which has a series of peaks in the frequency response to the input signal.
The peaks may be adjusted so that their frequencies are all multiples of a selectable frequency, all the way up to 24
kHz. When applied to a sound with a noise-like spectrum (white noise, with a flat spectrum, or cymbals, with a very
dense spectrum of many individual components), an output is produced which sounds very pitched, since most of
its spectral energy ends up concentrated around multiples of a fundamental frequency.
