-Devon's Whadul-
WHAT DOES IT DO?
Devon's Whadul is an amplitude based wah filter.
It uses a very simple 2 pole lp resonant filter
to add a 'wah' to the sound, based on the amplitude
of the incoming wave.
WHY?
Let me be honest with you: Everyone is writing lowpass
filters. But I find the expression filters hard to tweak.
Perhaps it is because I am not terribly bright, but
the general point of writing this is to make acheiving
similar effects easier.
PARAMETERS:
Response - This adjusts the rate at which the envelope
responds to the incoming signal.
Cutoff - Adjusts the 'approximate centre' frequency
of the filter.
Resonance- Adjusts the maximum amount of resonance applied
to the filter.
SPECS:
Envelope:Input amplitude based
Filter: 2 pole LP resonant filter.
