An engine/plugin for SFXEngine. Analogue VCF is a 24dB/oct low pass filter for SFXEngine designed to emulate the filter on an analogue synthesizer. The effect has a different sound and profile to the default Low Pass Filter engine, with a more pronounced Q, ideal for analogue-style bass sounds, or sweeping effects. Can be used as a program and/or environment engine.

Cutoff
Range 0.010 to 0.990
Cutoff frequency. All frequencies above this will be removed. The units are in the standard SFXEngine format where zero equals a frequency of 0hz and one equals a frequency of 22050hz.

Q
Range 0.001 to 1.000
Filter resonance. This controls the strength of a peak at the cutoff frequency so that high Q values effectively turn the filter into a peaking filter. This filter responds well to high resonance levels.

Wet
Range 0.0 to 1.0
Wet level. The degree to which this engine is applied. A value of one will apply the engine fully and a value of zero will bypass it and produce no audible effect.
