# Audio High Pass Simple Effect

> Reference for the Audio High Pass Simple Effect, which passes high frequencies and cuts off lower frequencies.

The **Highpass Simple Effect** passes high frequencies of an AudioMixer group and cuts off signals with frequencies lower than the **Cutoff Frequency**.

## Properties


**The AudioGroup Inspector displays the configurable property of an Audio High Pass Simple Effect.:**

| --------------- | ----------------------------------------------------------------------------- |
| **Cutoff freq** | Highpass cutoff frequency in Hertz (range 10.0 to 22000.0, default = 5000.0). |

## Details

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](/engine/6000.3/manual/audio/reference/effects/class-audio-high-pass-effect.md).
