High Pass
High Pass cuts frequencies below a cutoff — removing rumble, handling noise, or wind.
Parameters
| Parameter | Type | Range | Default | What it does |
|---|---|---|---|---|
| Cutoff Frequency | number | 20 to 5000 Hz | 80 Hz | Frequencies below this are attenuated. |
| Poles | number | 1 to 2 | 2 | Filter slope. 2 is steeper (cuts more decisively) than 1. |
| Width (Q) | number | 0.1 to 2 | 0.707 | Resonance/steepness right at the cutoff frequency. |
