What Equaliser is

Equaliser is a system-wide audio equalizer for macOS, applying processing to audio from every app. It offers up to 64 parametric EQ bands, each with independent frequency, gain, bandwidth or Q, and filter type controls. Compare Mode lets listeners switch between EQ settings and the original sound in real time, and 11 factory presets cover music, movies, and other uses. The 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. Audio processing happens locally; the app says it does not record, store, or transmit audio and has no analytics or telemetry. It is free and open source under GPL-3.0. It requires macOS 15 (Sequoia) or later and an Apple Silicon Mac. The app is not notarized by Apple, so macOS may require selecting Open Anyway in Privacy & Security settings.
