eqMini

eqMini is an open-source, lightweight equalizer for macOS that allows users to adjust audio output globally or on a per-application basis. It features a ten-band equalizer, simple tone controls, bass enhancement for small speakers, and local audio processing using Apple's Core Audio taps. The software is built with SwiftUI, requires macOS 14.2+ on Apple silicon, and does not use virtual audio drivers or send data externally, focusing on user privacy.
