About EQBase
EQBase is a native macOS app that puts an equalizer and a full set of audio controls in front of everything the Mac plays: browsers, calls, games, and system sounds, all at once. It ranges from a simple 3-control EQ to a 24-band parametric with dynamic and linear-phase filters, and includes correction curves for 8,666 measured headphone models, per-app volume and per-app EQ, per-app output routing, Audio Unit hosting, system audio recording, room measurement, and loudness compensation.
It adds zero latency to the direct signal, and when every control is flat the output is bit-perfect, verified continuously against the live audio. Setup needs one system permission: no admin password and no kernel extension by default.
The free tier has no time limit. Pro adds the advanced tools for $4.99/month, $39.99/year, or $79.99 once, with a 14-day refund. Requires macOS 14 or later, Apple silicon and Intel.
