Purpose: Equaliser is a system-wide audio equalizer for macOS.
Equalization: It provides up to 64 bands of parametric equalization, with independent frequency, gain, bandwidth/Q, and filter type controls for each band.
System audio: Audio from every app passes through the equalizer automatically.
Compare mode: Compare Mode lets users compare EQ settings with the original sound in real time.
Presets: The app includes 11 factory presets for music, movies, and more.
Audio specifications: The site lists a frequency range of 1 Hz–22 kHz, sample rates up to 768 kHz, and 32-bit float processing.
Integrations: Equaliser supports importing filter settings from Room EQ Wizard (REW).
Preset compatibility: The project README says Equaliser supports EasyEffects import and export to share presets with Linux users.
Audio routing: The README says a custom audio driver captures system audio and routes it through the app for processing.
Privacy: The README says audio processing happens locally and Equaliser does not record, store, or transmit audio or include analytics or telemetry.
Requirements: The app requires macOS 15 (Sequoia) or later and an Apple Silicon Mac.
Notarization: The maker says the app is not notarized by Apple and may require users to select Open Anyway in macOS Privacy & Security settings.
License: The maker identifies Equaliser as free and open source under the GPL-3.0 license.
