FabFilter Pro-Q 4 Alternatives — Every Price Point

Andrei Lupei · June 18, 2026 · 7 min read

FabFilter Pro-Q 4 at $179 is the standard but not the only EQ. Here are the best alternatives across all price tiers.

Free alternatives

• TDR Nova — 4-band dynamic EQ. Best free alternative. Covers most mixing EQ needs. Missing: band count, linear phase, collision detection, M/S per band.
• ReaEQ — unlimited bands, clean, flexible. Free with REAPER license, works as ReaPlugs outside REAPER.
• PT EQ-1A — Pultec emulation, free. Character EQ rather than precise studio EQ.

Mid-tier ($50-100)

• TDR Nova GE ($60) — upgrades free Nova with narrower band targeting and frequency-selective compression. Reasonable Pro-Q 4 substitute for most mixing tasks.
• Kirchhoff EQ ($70) — 40+ filter shapes, spectrum analyzer, good M/S support. The strongest Pro-Q 4 alternative under $100.

Professional alternatives ($150+)

• DMG Audio Equilibrium ($149) — extremely flexible, all phase modes, parallel processing. More complex to operate than Pro-Q 4 but equally capable.
• Sonible smart:EQ 4 ($149) — AI-assisted EQ that suggests settings based on target frequency profiles. Different approach than Pro-Q 4 — useful if you prefer algorithmic assistance.

Is Pro-Q 4 still the best?

Yes in 2026 for most mixing and mastering workflows. Kirchhoff EQ at $70 is the closest challenger at a lower price. For producers doing occasional EQ work, Kirchhoff is a reasonable alternative. For daily mixing and mastering, Pro-Q 4's workflow speed and collision detection justify the $179.
