FabFilter Pro-Q 4

The definitive surgical EQ. The late 2024 transition to 'v4' introduced 'Spectral Dynamics' (AI-assisted compression/expansion per band), 'Character Modes' for analog-style warmth, and 'EQ Sketch' for freehand curve drawing. It features native Dolby Atmos support up to 9.1.6 and industry-leading spectrum collision detection. While it is the most efficient and visually advanced EQ on the market, the $200 price point and the lack of a free tier have led to a surge in high-quality open-source rivals like ZL Equalizer.
