Parametric EQ

The Parametric EQ exposes 4 bands: a low shelf, two parametric (peaking) bands, and a high shelf.

Low Gain — Low shelf gain in dB, −18 to +18. Boosts or cuts everything below the low shelf frequency. Positive values add bass body and warmth; negative values clean up rumble or thin the low end. The shelf frequency itself isn’t separately exposed — drag the band point on the EQ widget to move it.

Mid1 Freq — Center frequency of the first parametric mid band, 100–4000 Hz. The lower of the two parametric (bell-shaped) bands. Useful for cleaning up muddy low-mids (200–400 Hz), boxy upper-bass (300–600 Hz), or boosting body and presence in the lower midrange.

Mid1 Gain — Gain at the mid1_freq band, −18 to +18 dB. Positive values boost the band; negative values cut. The Q (width) of each band is editable on the EQ widget — drag the band’s curve to adjust width. Tight Q for surgical notching; wide Q for tone shaping.

Mid2 Freq — Center frequency of the second parametric mid band, 500–16000 Hz. The upper of the two parametric bands. Covers the presence (1–4 kHz), brilliance (4–8 kHz), and air (8–16 kHz) regions. Use for vocal presence, snare crack, cymbal sheen, and similar.

Mid2 Gain — Gain at the mid2_freq band, −18 to +18 dB. Same role as mid1_gain but for the upper midrange band.

High Gain — High shelf gain in dB, −18 to +18. Boosts or cuts everything above the high shelf frequency. Positive values add air and brightness; negative values tame harshness or fizz.

Dry/Wet — Equal-power blend between dry (0) and the EQ’d signal (1). At 1 you hear the EQ; lower values blend the unprocessed signal back in. Mostly useful for parallel-style EQ where you want the EQ effect blended in rather than fully replacing the dry signal.

About Parametric EQ

The Parametric EQ exposes 4 bands: a low shelf, two parametric (peaking) bands, and a high shelf. The two shelf frequencies and all four band Qs (widths) are not on dedicated knobs — they’re edited directly on the EQ response widget by dragging the band points. Vertical drag = gain, horizontal drag = frequency, modifier-drag = Q. The animated knobs handle the most-changed parameters (the mid frequencies and the four gains); everything else is on the visual curve. This matches how most modern parametric EQs work (FabFilter Pro-Q, Pro Tools EQ III) — the curve is the interface.
