Graphic EQ –
Basically as above picture shows the ‘graphic’ eq is a series of sliders.
These sliders are preset values/frequencies – the curve is created by moving the sliders up and down.
A cut would mean pulling a slider down and a boost would mean moving the slider up.
Other Graphic EQ’s include these free vst versions
The Voxengo Overtone GEQ vst plugin
