Hey Product Hunt 👋
I'm Aakash, the solo dev behind EQK (and KUJA.dev).
This started with a small, dumb frustration. My headphones sounded great for one thing and wrong for another, and macOS gives you exactly one flat curve for the entire system. So I'd fix my music, then a video would sound harsh, then a song would sound thin. One machine, one sound, no nuance. That never made sense to me- every app, every track, every pair of headphones is different.
So the problem I set out to solve was simple to say and annoying to build: let every app on your Mac have its own sound, and stop making people babysit a single EQ curve.
The first version was static- per-app EQ plus AutoEq headphone correction. Useful, but I kept nudging bands manually every time a different genre came on, and I realized that's the real chore. So the approach evolved into what EQK is now: a dynamic engine that reads each song in real time and re-tunes on the fly.
The bigger evolution was philosophical. Early on I framed it as "fidelity" and "correction," and the audiophile crowd (rightly) pushed back hard- if you re-tune per song, you're not chasing neutral truth anymore. That feedback reshaped the whole product story. EQK isn't about lab-grade purity. It's about preference - how music feels, and compensating for the weaknesses in your actual gear. So I made the engine transparent and deterministic instead of a black box: you can see every layer, and lock any band you don't want touched.
Two things I care about a lot: no virtual audio drivers (it uses native macOS audio capture), and 100% local - audio never leaves your Mac, no telemetry, no accounts.
It's built by one person, so I'd genuinely love your feedback - what breaks, what's missing, what headphones you want profiles for. I'm here all day. 🙏
dynamic EQ that adjusts per track sounds nice in theory but I could see it working against you on an album that's mixed to sound consistent front to back, if every song gets re-tuned individually you'd lose that intentional flow. is there a way to lock the curve for a whole album/playlist once you land on something you like, or does it always re-analyze and adjust track by track no matter what
per-app EQ is the thing i wish existed every time a video is quiet and the music after it blows my ears out. auto tuning per song is a clever touch, and system audio on mac is a genuinely hard surface to build on
Been using this for a few days and the per-app EQ is genuinely wild, especially the auto tune per song feature. One thing I'd love to see is a simple way to save and recall whole output setups like a Home pair, work headphones, speakers, etc, so I don't have to remap every app when I switch.
