EQ Plug-ins


These are graphic equalizers. GEQ-30 has 30 available frequency bands.

geq 30

Each band can be attenuated or boosted by up to 12 dB, allowing for fine control of the frequency response. In addition, there are several preset modes available that can add color to the sound of GEQ-30.
You can draw response curves in the main display by clicking and dragging with the mouse. You have to click one of the sliders before you drag across the display.
At the bottom of the window, the individual frequency bands are shown in Hz. At the top of the display, the amount of attenuation/boost is shown in dB.


Allows you to adjust how much a set curve cuts or boosts the signal.


Sets the overall gain of the equalizer.


Inverts the current response curve.


Resets all the frequency bands to 0 dB.

EQ Modes

The Mode pop-up menu in the upper right corner allows you to select an EQ mode, which add color or character to the equalized output in various ways.

True Response

Applies serial filters with an accurate frequency response.

Digital Standard

In this mode, the resonance of the last band depends on the sample rate.


Applies a classic parallel filter structure where the response does not follow the set gain values accurately.


Applies parallel filters where the resonance depends on the amount of gain.

ConstQ asym

Applies parallel filters where the resonance is raised when boosting the gain and vice versa.

ConstQ sym

Applies parallel filters where the resonance of the first and last bands depends on the sample rate.


Applies serial filters where a gain increase of one band lowers the gain in adjacent bands.
