Per-app macOS equalizer with on-device AI song analysis and 3,985 bundled headphone correction profiles — nothing leaves your Mac.
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.

EQK is designed to enhance the audio experience for music enthusiasts and content creators alike. Here’s how it works:
Per-App Patchbay Routing: EQK allows users to route individual music and video applications through separate equalizer settings. This prevents mixed audio signals from contaminating each other, ensuring clarity and precision in sound quality.
AI Song Live Analysis: The smart on-device engine of EQK analyzes each track as it begins to play. It dynamically reshapes the audio tone in real-time while applying per-app equalization and headphone correction. This feature is particularly beneficial for audiophiles who want to hear music as intended.
3,985 Headphone Correction Profiles: EQK includes a comprehensive library of AutoEq correction curves tailored for a wide range of headphones, earphones, and in-ear monitors (IEMs). The AI uses these profiles to adjust audio output based on the specific characteristics of the user’s audio gear, enhancing the listening experience.
User Tweaks Stay On Top: Manual EQ adjustments made by users are prioritized, ensuring that personal sound preferences are not lost to AI corrections. This allows for a fully customized audio experience.
Fully On-Device Privacy: Unlike many audio processing tools, EQK operates entirely on the device without requiring user accounts or cloud connectivity. This means all listening data remains private, making it ideal for privacy-conscious users.
Practical Applications:
EQK offers features like Per-App Patchbay Routing for independent equalization of audio applications, real-time AI Song Live Analysis for dynamic tone adjustments, and a vast library of 3,985 headphone correction profiles.

The AI Song Live Analysis feature utilizes an on-device engine that assesses the audio track as it plays. It adjusts the tonal quality in real-time, optimizing the sound output based on the per-app equalization settings and headphone correction profiles. This ensures that listeners experience the best possible sound tailored to their specific audio setup.

Isolating App Audio: EQK enables users to tune audio from different apps separately.
