Low Pass
Low Pass cuts frequencies above a cutoff — softening harshness, sibilance, or high-frequency hiss.
Parameters
| Parameter | Type | Range | Default | What it does |
|---|---|---|---|---|
| Cutoff Frequency | number | 500 to 20000 Hz | 10000 Hz | Frequencies above this are attenuated. |
| Poles | number | 1 to 2 | 2 | Filter slope. 2 is steeper than 1. |
| Width (Q) | number | 0.1 to 2 | 0.707 | Resonance/steepness right at the cutoff frequency. |
