EQ: Parametric effect

The EQ: Parametric effect provides maximum control over tonal equalization. Unlike the graphic equalizer, which provides a fixed number of frequencies and Q bandwidths, the parametric equalizer gives you total control over frequency, Q, and gain settings. For example, you can simultaneously reduce a small range of frequencies centered around 1000 Hz, boost a broad low‑frequency shelf starting around 80 Hz, and insert a 60-Hz notch filter.

Use the standard version of this effect to quickly apply preset equalization curves. Use the advanced version to precisely adjust such curves.

Standard settings

Amount

Controls the ratio of original to equalized sound.

Advanced settings

Graph

Shows frequency along the horizontal ruler (x‑axis) and amplitude along the vertical ruler (y‑axis), with the curve representing the amplitude change at specific frequencies. Frequencies in the graph range from lowest to highest in a logarithmic fashion (evenly spaced by octaves).

Drag control points in the graph to visually adjust settings below.

Highpass and Lowpass Enable

Activate shelving filters at either end of the frequency spectrum.

Band Enable

Activates a peaking filter in the center of the frequency spectrum.

Hz

Indicates the center frequency of each frequency band.

dB

Indicates the level of each frequency band.

Q

Controls the width of the affected frequency band. Low Q values (up to 3) affect a larger range of frequencies and are best for overall audio enhancement. High Q values (6–12) affect a very narrow band and are ideal for removing a particular, problematic frequency, like 60-Hz hum.
