SystemEQ for Mac
Free system-wide parametric audio EQ for macOS
SystemEQ is a free, open-source system-wide parametric equalizer for macOS. • 10/31-band EQ with vDSP biquad filters for ultra-low latency & CPU usage • Built-in AutoEQ database with 8,665 headphone models (oratory1990, Crinacle) • Real-time visualizer & room calibration tools • 100% free (GPLv3), no subscriptions, no ads, no telemetry.
Hi Product Hunt! 👋 I'm Denys, creator of SystemEQ.
By day I assemble medical devices, and in my spare time I build audio tools for macOS.
I created SystemEQ because Mac lacks a native system-wide equalizer. Existing commercial solutions cost $39+ or lock features behind recurring subscriptions. I wanted a fast, native, open-source tool that lets you fine-tune the sound for any headphones or speakers.
✨ Key highlights:
• 10/31-band parametric EQ using Apple Accelerate (vDSP) for near-zero CPU footprint.
• Offline AutoEQ database: 8,665 headphone models ready in one click.
• Hearing calibration & room resonance sweep.
• Real-time audio visualizer powered by ProjectM.
• 100% free and open source (GPLv3) — no telemetry, no tracking, no subscriptions.
Install via Homebrew:
brew trust denzam/systemeq && brew install --cask denzam/systemeq/systemeq
Or download from GitHub: https://github.com/denzam/System...
I'd genuinely love your feedback, feature ideas, and thoughts on the app!
