Equaliser vs Nahimic

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.

Nahimic is audio software designed for music, movies, communications, and gaming through devices such as internal speakers, headphones, and speakers. Its 3D Sound engine uses head-related transfer function calculations to recreate directional audio as a multichannel sound field on stereo devices. Sound Tracker presents predominant sound directions on a customizable 360° radar overlay. Gaming features include Surround Sound, Device Compatibility, Volume Stabilizer, Voice Stabilizer, and Night Mode. Voice Stabilizer and Static Noise Suppression are intended to support clearer, steadier game communications; Volume Stabilizer helps keep levels more consistent. Night Mode reduces bass and lowers general volume to 50%, with a 10 dB volume reduction. Supported connections include Bluetooth, USB, analog, HDMI, and S/PDIF. Nahimic is free and targets Windows, MacOS, and mobile devices. Its download archive lists compatible computer models for Nahimic 2+ and Nahimic 3 rather than promising support for every computer, and the gaming page advises updating the audio driver before updating the software.
