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

Per-App Patchbay Routing: Route individual music and video apps through independent equalizers so mixed browser audio never contaminates the signal chain.
AI Song Live Analysis: An on-device engine analyzes each track as it starts and reshapes tone in real time over the per-app EQ and headphone correction.
3,985 Headphone Correction Profiles: Bundled AutoEq correction curves for a wide catalog of headphones, earphones, and IEMs are read by the AI to compensate for gear response.
User Tweaks Stay On Top: Manual EQ adjustments always sit on top of AI and correction lanes, so listener taste is never overwritten.
Fully On-Device Privacy: All analysis happens locally with no signup, no cloud, and no accounts — nothing leaves the Mac.
Apple-Notarized macOS App: Distributed as a notarized native app for macOS 15.6+ with a free player tier that remains free forever.
Buy-Once License: A one-time ₹1,000 Premium purchase activates on up to two Macs and includes free updates for the EQK 1.x line.

Audiophile Listening on Mac: Music enthusiasts pair headphone correction with AI song analysis to hear a corrected, tone-matched signal on their exact gear.
Content Creator Monitoring: Editors and streamers route their DAW or video app through EQK to preview mixes against a corrected reference.
Isolating App Audio: Users tune podcasts, music, or video separately so switching apps does not mean re-EQing every time.
Privacy-Conscious Listeners: Anyone unwilling to send listening data to the cloud gets AI-driven EQ that runs entirely on device.
IEM and Headphone Reviewers: Reviewers with many pairs compare gear against consistent AutoEq baselines and their own taste tweaks.
Free Player for Casual Users: Users who want basic per-app EQ without AI keep the free player tier indefinitely.
