wah-plugins - 0.1.0-5 main

This LADSPA plugin is the combination of a 'wah' pedal and
a simple envelope follower.
.
Controls are:
- Freq: the resonance frequency of wah filter.
This would normally be controlled using a
midi pedal.
- Mix: crossfades between dry and wet signal, the
first is the original input signal and the latter
is the pure output of the resonant filter amplified
by 18 dB.
.
The three remaining parameters control the envelope
follower. This produces a control signal that is
added to the 'Freq' setting.
- Drive: input gain to the envelope follower (so
this gain is not in the signal path).
- Decay: controls the decay time of the envelope.
- Range: controls how much the envelope is allowed
to modify the basic frequency.
