Atrium measures how you listen, then reshapes everything your computer plays to match. This is why we built it.
Every piece of audio you've ever heard was mixed for an ear that doesn't exist. Listening is as individual as a fingerprint — on three layers:
The audio industry spent a decade in controlled listening tests searching for the tuning the average person prefers. The result became the reference standard headphone makers tune to — and even it satisfies only about two thirds of listeners. The industry's best one-size-fits-all answer misses a third of humanity.
No two ears are shaped alike, and almost no one hears symmetrically between their own two. Your sensitivity varies across the frequency range in a pattern that's yours alone — yet almost no consumer software ever measures it.
Around 1.5 billion people already live with some degree of hearing loss — projected to reach 1 in 4 humans by 2050 — and over a billion young adults are at risk from unsafe listening. Sound that adapts to your hearing isn't a luxury; it's overdue.
The industry's answer to all this variety is to ship one tuning per product and let demographics average out. The result: every listener is hearing someone else's compromise.
Atrium builds a profile of you in about fifteen minutes, through five short listening tests — hearing thresholds, loudness sensitivity, sound separation, spatial perception, and a taste test that turns simple A/B choices into a picture of the sound you actually prefer. We call the result your Signature.
The engine then applies it to everything your computer plays: a personal EQ, per-ear balance, correction profiles for your headphones, real acoustic rooms, and a 3D spatial mixer. Every adjustment you make teaches it a little more. The longer you listen, the more yours it sounds.
The quietest sounds you can hear, ear by ear.
How your sensitivity changes across frequencies.
How well you pick details out of a busy mix.
How you locate sound in space — front, back, above.
A/B choices that map the sound you love.
A profile of how you hear is personal — close to biometric. So Atrium is built the only way we'd accept ourselves: no accounts, no cloud, no tracking. Your hearing data and your audio never leave your machine. The tests run on your device, the engine runs on your device, and deleting everything takes one click.
Say what you mean — "warmer," "bring the vocals out," "less harsh" — and have it translated into your tuning. Real-time instrument enhancement that can lift a bass line or push dialogue forward in any stream. An engine that adapts to what you're playing, on its own.
From 27 curated correction profiles today to the open measurement ecosystem — thousands of models, plus community-shared rooms and presets.
Atrium runs on Windows today, with macOS next — and a longer-term vision where your Signature follows you to every device you listen on.
