The Highpass Effect passes high frequencies of an AudioMixer group and cuts off signals with frequencies lower than the Cutoff Frequency.
 
| Property: | Function: | 
|---|---|
| Cutoff freq | Highpass cutoff frequency in Hertz (range 10.0 to 22000.0, default = 5000.0). | 
| Resonance | Highpass resonance quality value (range 1.0 to 10.0, default = 1.0). | 
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.
