Function:

Cutoff freqLowpass cutoff frequency in Hertz (range 10.0 to 22000.0, default = 5000.0).
ResonanceLowpass resonance quality value (range 1.0 to 10.0, default = 1.0).

Details

The Resonance (short for Lowpass Resonance Quality Factor) determines how much the filter's self-resonance is dampened. Higher lowpass resonance quality indicates a lower rate of energy loss, that is the oscillations die out more slowly.
