What is SystemEQ for Mac?

SystemEQ is a free, open-source system-wide parametric equalizer for macOS 13+. It allows you to tune all system audio — Spotify, YouTube, Apple Music, browsers, and any other app.

Key features: • 10/31-band parametric equalizer with biquad filters powered by Apple's Accelerate framework (vDSP). • Built-in offline AutoEQ database with 8,665 headphone models and 8,850 presets (oratory1990, Crinacle, etc.). • Hearing calibration module with A/B comparison and subjective room tuning tools. • Real-time audio visualizer (spectrum, waveform, psychedelic modes via ProjectM). • Low-latency audio processing via AUHAL and BlackHole virtual driver. • Zero telemetry, no ads, no subscriptions — 100% free and open source (GPLv3). • Available via Homebrew Cask and direct DMG/ZIP download.
