A clear view.
A precise move.

Work on the frequency graph, then refine the selected band with exact frequency, gain and Q values. Every band has its own filter shape and bypass.

Clear the low end

Choose a low cut to reduce rumble, then set its frequency and slope to leave the useful body of the recording intact.

12 to 48 dB per octave

Four cut slopes let you choose between a gentle roll-off and a steeper boundary.

Give each part room

Use a broad bell to reshape the mids or a narrower cut to reduce a resonance. Drag the band into place and type a value when you need precision.

Frequency, gain and Q

Adjust the center frequency, amount and bandwidth independently, then compare in the full mix.

Balance the whole tone

Use low and high shelves for wider changes in weight and brightness. Watch the input and output spectra together to see how your curve changes the balance.

Compare at the same level

Trim Output after a boost and use bypass to judge the tonal change without a louder signal winning by default.

The controls

The response graph takes the center of the interface. The selected band’s controls stay close at hand.

Eight bands

Select a band on the graph to edit it. Each band has its own frequency and filter shape, with gain and Q controls where the selected shape uses them.

Seven shapes

Choose Bell, Low Shelf, High Shelf, Low Cut, High Cut, Notch or Band Pass for each band. Combine broad shaping with focused filtering in one instance.

Cut slopes

Low Cut and High Cut offer 12, 24, 36 and 48 dB per octave. Set the cutoff first, then choose the slope that suits the surrounding sound.

Live spectrum

Input and output spectrum traces show the energy across the frequency range alongside the EQ response. Use them to orient a move, then listen to the result.

Factory presets

Start from a prepared curve for common sources, then adjust it to your recording. The graph shows every band so the preset is easy to understand and change.

Output and bypass

Set the final output level and compare the full EQ with bypass. Individual band bypass lets you check one adjustment at a time.
