About EQK

EQK is a Mac utility that gives every app its own equalizer, then layers an on-device AI Song engine on top that analyzes each song as it starts and reshapes tone in real time — always keeping the user's manual tweaks on top. A Correction lane holds 3,985 AutoEq headphone profiles so the AI understands exactly what your headphones, earphones, or IEMs under- and over-deliver. Music and video apps can be routed through independent equalizers via a Patchbay, so browsers with mixed audio never contaminate the signal. EQK is fully on-device with no cloud, accounts, or telemetry, is notarized by Apple, and requires macOS 15.6 or later. It is sold as a one-time purchase — the local player stays free forever, while Premium unlocks the full experience across up to two Macs.
