FabFilter Pro-Q 4 is a flagship parametric EQ plugin for mixing, mastering, and sound design, built for fast problem solving and clean musical shaping in any DAW. If you already know Pro-Q 3, Pro-Q 4 takes that workflow further with Spectral Dynamics, EQ Sketch curve drawing, an Instance List for multi-instance control, and advanced dynamic EQ across up to 24 bands, making it a serious daily-driver EQ for producers and engineers.
🎛️ What’s Inside
| Module / Feature | What it does | Perfect for |
|---|
| Up to 24 EQ Bands | High-precision EQ bands with multiple filter types, steep slopes up to 96 dB/oct, plus brickwall low/high cut options. | Surgical cleanup, tone shaping, mastering EQ, corrective mixing. |
| Dynamic EQ (All Bands) | Turn any band into dynamic EQ with attack and release control, sidechain filtering, and optional external triggering. | De-harshing vocals, taming resonances, tightening low end, dynamic tone control. |
| Spectral Dynamics | Advanced frequency-dependent dynamics to precisely control problem areas without over-EQing the whole signal. | Resonance control, harshness cleanup, dynamic mids, modern mix clarity. |
| EQ Sketch | Draw an EQ curve directly to set up initial shaping fast, then refine with normal bands. | Fast workflow, quick tonal shaping, creative sound design moves. |
| Instance List and Session Control | View and control other Pro-Q 4 instances in your session, speeding up mix decisions and A/B checking. | Large sessions, mix organization, consistent tone across busses. |
| Mid/Side and Left/Right Processing | Per-band processing modes so you can EQ center vs sides, or left vs right independently. | Stereo imaging, vocal center cleanup, widening, mastering control. |
| Zero Latency, Natural Phase, Linear Phase | Choose the mode that fits your session: real-time tracking, natural phase shaping, or linear phase mastering precision. | Tracking, mixing, mastering, phase-sensitive EQ moves. |
| Spectrum Grab and EQ Match | Grab peaks directly from the analyzer and optionally match the spectrum of another instance or external signal. | Fast resonance fixes, reference matching, consistent tonal targets. |
| Character Modes (Gentle and Warm) | Optional character modes that add subtle analog-style color while staying clean and controlled. | Musical EQ sweetening, mix glue, less sterile shaping. |

💡 Pro Tip
When a vocal feels harsh only on certain words, do not hard-cut the whole frequency range. Use a dynamic bell or Spectral Dynamics around the harsh area, set a moderate attack and release, and let it clamp down only when it gets spiky. You keep the air and presence, but the listener stops wincing on the loud parts.
