The interface of FabFilter Pro-Q 3 is simple and straightforward. The interactive EQ display
fills the whole plug-in window, and lets you create and adjust EQ bands using the mouse. When you
create or select bands, the band controls will appear, floating above the display, positioned
under the selected bands. Using the band controls, you can change the settings of the currently
selected EQ bands. The bottom bar offers features like processing mode (zero latency, Natural
Phase or linear phase), spectrum analyzer settings, global
bypass, phase-invert, auto-gain, gain scale and output level/panning.
