EQK

Adjust supported Mac apps with separate equalizer curves, output levels, and headphone profiles.

Meet EQK

EQK is a Mac equalizer that saves separate sound settings for supported applications. Listeners can assign a ten-band EQ curve, output level, device route, and headphone correction profile to music players, podcast apps, or video players. Changing one application's settings leaves the others in place.

AutoEq-derived headphone profiles provide a correction starting point, while optional on-device AI Tune adjusts a song or remembers a completed profile. A built-in player handles local FLAC, ALAC, WAV, and MP3 files through the same controls. Compatibility depends on the audio source: ordinary browser tabs and some protected audio cannot be isolated as separate routes.
