What Equaliser is

Equaliser is a free system-wide audio equalizer for macOS that processes audio from every app automatically. Its parametric equalizer supports up to 64 bands, with independent frequency, gain, bandwidth/Q and filter type controls for each band. Compare Mode lets listeners compare adjusted settings with the original sound in real time, and 11 factory presets cover music, movies and other uses. Listed audio specifications include a 1 Hz–22 kHz frequency range, sample rates up to 768 kHz and 32-bit float processing. Equaliser can import filter settings from Room EQ Wizard and supports EasyEffects import and preset export for sharing with Linux users. The project is free and open source under GPL-3.0. Audio processing happens locally; the app says it does not record, store or transmit audio and does not include analytics or telemetry. Equaliser requires macOS 15 (Sequoia) or later and an Apple Silicon Mac. It is not notarized by Apple, so macOS may require selecting Open Anyway in Privacy & Security settings.
