2nd order SideBandFilter
By boosting the fundamental and overtones, you can
apply a pitch to unpitched input sounds such as noise
or a drum phrase. This lets you create a stronger effect
than the first-order sideband filter.
Comb Filter
A comb filter can be used to boost or cut the
fundamental or overtones.
Dual Filter
Two filters can be connected in series or parallel.
