The Highpass Simple Effect passes high frequencies of an AudioMixer group and cuts off signals with frequencies lower than the Cutoff Frequency.
|Cutoff freq||Highpass cutoff frequency in Hertz (range 10.0 to 22000.0, default = 5000.0).|
The Resonance (short for Highpass Resonance Quality Factor) determines how much the filter’s self-resonance is dampened. Higher highpass resonance quality indicates a lower rate of energy loss, that is the oscillations die out more slowly.
For additional control over the resonance value of the high pass filter use the Audio High Pass effect.
