Parametric EQ (5-band)
Parametric EQ (5-band) shapes tone across five fixed frequency bands — the general-purpose tool for boosting or cutting specific parts of the frequency spectrum.
Parameters
| Parameter | Type | Range | Default | Center Frequency |
|---|---|---|---|---|
| 100Hz | number | -15 to 15 dB | 0 dB | 100 Hz |
| 300Hz | number | -15 to 15 dB | 0 dB | 300 Hz |
| 1kHz | number | -15 to 15 dB | 0 dB | 1000 Hz |
| 3kHz | number | -15 to 15 dB | 0 dB | 3000 Hz |
| 10kHz | number | -15 to 15 dB | 0 dB | 10000 Hz |
How it works
Each band is a moderately narrow peaking (bell-shaped) boost/cut centered on its fixed frequency — the center frequencies themselves aren't adjustable, only the gain at each one.

Bass and Treble for broad shelf-style tone controls instead of targeted bands; High Pass/Low Pass for cutting everything above or below a cutoff entirely.
