This is an upgrade from Pro-Q 1, Pro-Q 2, or Pro-Q 3. FabFilter Pro-Q 4 combines pristine sound quality with an exceptionally fast and intuitive workflow, giving engineers powerful tools for both mixing and mastering. Its advanced processing modes, dynamic and spectral EQ options, and refined interface make precise, musical shaping effortless.

Mixing and Mastering Features

Pro-Q 4 delivers everything needed for professional work: zero-latency, Natural Phase, and linear-phase modes; smooth dynamic and spectral EQ behavior; per-band mid/side control; full surround support up to Dolby Atmos 9.1.6; Auto Gain; intelligent soloing; and a fully customizable spectrum analyzer.

Effortless Sound Sculpting

The large interactive EQ display makes shaping sound fast and intuitive. Users can sketch or add bands instantly, enable dynamic EQ per band, adjust multiple bands at once, and speed up their workflow with tools like Spectrum Grab, Full Screen mode, and EQ Match.

FabFilter Workflow Essentials

Included are all signature FabFilter conveniences: precise, responsive controls; MIDI Learn; undo/redo; A/B comparison; Smart Parameter Interpolation; extensive help resources; sample-accurate automation; and highly optimized performance.

Unified Control of All Instances

The Instance List provides centralized control of every Pro-Q 4 instance within a session. Sorting, pinning, and zooming options streamline navigation and accelerate initial EQ setup in complex mixes.

Spectral Precision for Problem Frequencies

In Spectral Dynamics mode, only the specific frequencies that exceed the threshold are affected, preserving the rest of the band. This powerful approach handles resonances and fluctuating problem tones without the complexity of a dedicated processor.

Draw EQ Curves Instantly

EQ Sketch allows users to draw the desired curve in a single gesture. Pro-Q 4 automatically translates it into the optimal combination of filters, making it fast and intuitive to create starting points or detailed shapes.
