EQK-2AI for Mac
EQK-2AI is a per-app equalizer for Mac that combines routing, headphone correction, and live song analysis. It is presented as an app that listens to each track as it starts, adjusts tone in real time, and keeps the work on-device rather than in the cloud.
The product is built for users who want separate sound treatment for different apps, especially music and video players. The homepage also highlights bundled AutoEq correction profiles, a free 14-day trial, notarization by Apple, and a one-time premium purchase model.
License help explains that the purchase is tied to your purchase email, with key re-sends available if needed. EQK Premium can be activated on up to two Macs, and Migration Assistant is said to carry the license over automatically.
Features
Song-by-song live analysis
Analyze each song as playback starts and apply tonal changes in real time over per-app EQ and headphone correction.
Headphone correction profiles
Use bundled AutoEq correction for the headphones, earphones, or IEMs you actually use, with a built-in profile library.
On-device operation
Keep processing local to the Mac; the site states that nothing leaves your Mac and that EQK uses on-device intelligence with no cloud or accounts.
Full trial and one-time purchase
Try the full app for 14 days without signup, then buy EQK Premium as a one-time license if you want to keep it.
Flexible license transfer
Activate the license on up to two Macs and move it later if your setup changes.
Common use cases
Separate tuning for music apps
Route a music player through its own EQ so you can tune it independently from everything else on the Mac.
Isolate sound per app
Apply different correction to browsers, media players, or other video apps while keeping mixed tabs from affecting the sound path.
Headphone and IEM correction
Use the bundled headphone profiles to compensate for the specific response of your headphones, earphones, or IEMs.
Quick first-listen evaluation
Install the trial, route one app, and press play to hear how live analysis and correction behave on a real track.
Reinstall or move to another Mac
Move EQK to a second Mac or reinstall it without losing access, using the license tools and keychain-based activation flow.
