FabFilter Fabfilter Pro-Q 4 EQ and Filter Plug-In – Software

Unrivaled sound and workflow

An equalizer is probably the tool you use most while mixing and mastering, so you need the best of the best. FabFilter Pro-Q 4 delivers with the highest possible sound quality, a very extensive feature set, and a gorgeous, innovative interface with unrivaled ease of use.

Mixing and mastering features

Pro-Q 4 offers everything that a demanding engineer could wish for: top-quality linear phase operation in addition to the zero latency and unique Natural Phase modes, smooth dynamic and spectral EQ, per-band mid/side processing, full surround support (up to Dolby Atmos 9.1.6), an intelligent solo feature, optional Auto Gain and a built-in, fully customizable spectrum analyzer.

Effortlessly sculpt your sound

FabFilter Pro-Q 4 is designed to help you achieve your sound in the quickest way possible. Via the large interactive EQ display, you can add or sketch bands where you need them, enable dynamic EQ for any band, and select and edit multiple bands at once.

Unique features like Spectrum Grab, Full Screen mode and EQ Match will speed up your workflow even more. Try it yourself!

FabFilter goodies

Of course, you also get all the usual FabFilter goodies: perfectly tuned knobs, interactive MIDI Learn, undo/redo and A/B switch, Smart Parameter Interpolation for smooth parameter transitions, an extensive help file with interactive help hints, sample-accurate automation, advanced optimization and much more.

All your Pro-Q 4 instances in one interface

With Pro-Q 4, you can control any other plug-in instance in your session from a single interface, easily navigating the list by filtering, pinning and zooming as desired.

You will discover that the Instance List is a huge time-saver, making it much easier to setup initial EQing when starting your mix session.

Precise treatment of problem frequencies

In Spectral dynamics mode, Pro-Q 4 doesn’t change the gain of the whole band, but triggers per specific frequency within a band when it exceeds the threshold, leaving other frequencies untouched. This is a great way of treating varying problem frequencies.

Typically, you would need a separate and often complex plug-in for this type of processing, but Pro-Q 4 makes the process simple to use and easy to understand, as a natural extension of normal dynamic processing.

EQ Sketch and usability

Just draw the curve you need

Setting up initial EQ settings in an equalizer often involves adding a few general bands to get started, like a low cut filter, a few bell filters and a high shelf, creating a general starting point.

Wouldn’t it be great if you could draw that curve in one gesture? Well… now you can with EQ Sketch!
