eqMac vs Equaliser

eqMac is a system-wide audio equalizer and volume mixer for macOS. The free tier includes basic bass, mids and treble controls and a fixed 10-band equalizer. AutoEQ provides automatic headphone equalization from frequency responses, with support listed for 4,600 headphone presets. Pro adds unlimited customizable bands, a real-time spectrum analyzer, separate left and right channel EQ, AudioUnit hosting, spatial audio and per-application volume mixing. The maker says its driver captures system audio and passes it to the app through a secure memory tunnel for processing; it also says the driver runs in user space rather than the kernel. Downloads are listed for macOS 10.13 or later on Intel and Apple Silicon. The maker lists a free HTTP API for controlling eqMac, and remote control from iOS, iPadOS or Android devices on the same local network as a Pro feature. The free plan has no Pro features. Paid access is listed from $1/mo, while the Pro subscription page does not state a yearly price. Public GitHub code corresponds to version 1.3.2 without Pro features; newer releases are developed on a private fork.

Equaliser is a system-wide audio equalizer for macOS that processes audio from every app automatically. It offers up to 64 parametric EQ bands, each with separate controls for frequency, gain, bandwidth or Q, and filter type. Compare Mode lets users hear adjusted settings against the original sound in real time, and 11 factory presets cover music, movies, and other uses. Listed 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; the project also supports EasyEffects import and exporting presets for sharing with Linux users. Processing happens locally, and the app says it does not record, store, or transmit audio or include analytics or telemetry. It is free and open source under GPL-3.0. The app 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.
