ABOUT US
At ALTITUDE, we began with a simple observation: traditional hearing tests were imprecise, and existing sound personalization solutions compromised audio quality. Our founder assembled a world-class team with over a century of combined expertise to revolutionize how we experience sound.
By merging cutting-edge research with audio mastery, we've created two groundbreaking innovations: the industry's first calibrated, full-spectrum hearing test, and ARIA Studio—our high-resolution hearing refinement technology. Together, they deliver unprecedented audio precision. Your detailed test results inform ARIA's sophisticated algorithms, creating a personalized hearing profile that optimizes your listening experience across all devices and environments.
Our vision is clear: a world where precise hearing tests are the norm, where software transcends hardware limitations, and where everyone can experience sound exactly as it was meant to be heard.

We're redefining the audio experience through advanced software-based hearing refinement, free from the constraints of traditional hardware and lossy processing. Our flagship technology, ARIA Studio, delivers pristine, high-resolution sound personalization that preserves every nuance of your music.
With ARIA Studio, you'll discover a new dimension of sound: feel the intimate breath of a vocalist, experience the full impact of deep bass lines, and immerse yourself in a holographic soundstage that brings your music to life.
Join us on a journey to audio perfection, where every detail matters and nothing is lost.

Our exclusive FullScale Hearing Test serves as the foundation of our entire product line. The results from this test inform ARIA Studio, our advanced sound personalization software.
The FullScale Hearing Test is the only option to obtain your full spectrum hearing profile. With a resolution nine times greater, it uniquely captures the nuanced functions of your hearing perception.
ARIA represents a transformative leap in psychoacoustic software for macOS and Windows. It calibrates sound across all devices to match your unique hearing profile, operating independently of hardware limitations.
Driven by our mission to champion barrier-free hearing, we've designed ARIA with open-use and open-source flexibility. Our goal is for you to experience the advantages of your system on your terms. We've even streamlined the integration of ARIA into any capable third-party software with our convolution files.
