An equalizer is probably the tool you use most often when mixing and mastering, so you want the best of the best. With FabFilter Pro-Q 4, you get the highest possible sound quality, a very comprehensive feature set, and a great, innovative interface with unrivaled ease of use.

Features of mixing and mastering

Pro-Q 4 offers everything a demanding sound engineer could want: high-quality linear phase processing in addition to zero latency and unique Natural Phase modes, smooth dynamic and spectral EQ, midrange and sideband processing for each band, full surround support (up to Dolby Atmos 9.1.6), intelligent Solo function, optional automatic gain and a built-in, fully customizable spectrum analyzer.

Create your own sound easily

FabFilter Pro-Q 4 is designed to help you achieve your sound in the fastest possible way. With a large interactive EQ display, you can add or drag 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!

All your Pro-Q 4 instances in one interface

With Pro-Q 4, you can manage any other plug-in instance in a session from a single interface, easily navigating the list, filtering, pinning, and scaling as desired. You’ll find that the instance list is a huge time saver, making the initial EQ setup much easier when starting a mixing session.

FabFilter Goodies

Of course, you also get all the usual FabFilter benefits: perfectly tuned knobs, interactive MIDI learn, undo/redo and A/B switch, intelligent parameter interpolation for smooth parameter transitions, an extensive help file with interactive tooltips, sample-accurate automation, advanced optimization, and more.

Precise handling of problem frequencies

In Spectral Dynamics mode, Pro-Q 4 does not change the gain of the entire band, but rather acts on a specific frequency within that band when it exceeds a threshold, leaving other frequencies untouched. This is a great way to deal with various problem frequencies in your audio.

Typically this type of processing requires a separate, dedicated and often complex plugin, but Pro-Q 4 makes the process easy to use and understandable, being a logical extension of regular dynamics processing.

Simply draw the curve you want

Setting up the initial EQ settings in an equalizer often involves adding a few common bands to begin with, such as a low-pass filter, some bell filters , and a high-shelf, creating a general starting point.

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