A chain of modules!
Parametric filter
A parametric filter changes the frequency response of the
signal. It has a span of 50Hz to 12kHz. The adjustment
level spans +-16 dB. The Q-value (bandwidth) can be 0.1
to 10. You can choose between EQ, high shelf or a low
shelf filters)
Noise gate
The noise gate operates in 3 separate bands, 1Kz, 3kHz
and 5kHz. The knobs define the sensitivity of the gating.
When the signal is low enough it will be attenuated 16 dB
in that band. The noise gate also has a built-in hum filter.
60Hz for the US and 50Hz for Europe. Other parts of the
world may or may not have different AC frequency com-
ing out of the wall...
Auto Wah-Wah
A Wah-Wah is usually a stomp box where the guitar
player dynamically changes the frequency of a filter. By
stomping on a pedal, the signal is amplified in a sharp fre-
quency band, the center of which is defined by the posi-
tion of the foot. This is very useful, but hard to implement
in a DirectX plugin. Instead of the foot, the Wah-Wah
(now called “auto”) is controlled either by a BPM value
(non smart mode) or by the signal content (smart modes).
The speed controls how fast the signal is to glide up and
down the frequency scale. The range defines the total
change of the frequency, usually between 200-2000 Hz).
