Audio Low Pass Effect

The Audio Low Pass Effect passes low frequencies of an AudioMixer group while removing frequencies higher than the Cutoff Frequency.


Property: Function:
Cutoff freq Lowpass cutoff frequency in Hertz (range 10.0 to 22000.0, default = 5000.0).
Resonance Lowpass resonance quality value (range 1.0 to 10.0, default = 1.0).


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.
