Your hearing.
Your way.

This is OtoCorrect, your one-stop shop to observe and protect your hearing from the comfort of your own home.

1

Distance

Uses your camera to estimate how far you're sitting from the screen, and flags whether you're in a comfortable range for face-to-face hearing and lip visibility.

2

Sound

Shape a test sound with a simple equalizer to find what's clearest for you.

3

Hearing Test

A one-minute, self-guided pure tone audiometry check across six frequencies — a supplement to clinical care, not a replacement for it.

Everything runs locally in your browser. This is a comfort tool, not a diagnostic device.

Distance

Find your hearing sweet spot

Center your face in the frame. We'll estimate your distance and flag your ideal hearing range.

Camera access needed

We need your camera to estimate distance. Nothing leaves this browser tab.

Volume by distance

Off

Closer to the camera → quieter. Farther away → louder. Applies to whichever of the outputs below are turned on.

The test tone only controls audio played on this page. Browsers don't allow a website to change your computer's overall system volume.

Spotify playback volume

Connect your Spotify account to let distance control the volume of whatever is playing on your active Spotify device.

Sound

Shape sound to your ears

Play a built-in test sound and reshape it with six frequency bands, from low bass up through treble. Try a preset for a common comfort curve, or drag each slider to build your own.

Hearing Test

Pure Tone Audiometry

A supplement to your audiologist's exam between visits — not a replacement for it — across six frequencies (250 Hz–8 kHz), followed by ten spoken words at varying volumes. Put on headphones in a quiet room, set a comfortable volume, and click the button the moment you hear each tone. When the word portion starts, we'll ask for one-time microphone access — words are spoken aloud, never shown on screen, so just say back what you hear. Full results appear together at the end.

Hearing Test powered by ElevenLabs

One pass through all six frequencies, played to both ears at once — good for a quick, general check. Results plot as a single line.

Language

The six frequencies are just tones — this only affects the spoken words in the second half of the test.

Speaker · ElevenLabs

Pick an AI voice to read the words aloud. The list updates to match the language selected above.

Extension

OtoCorrect, everywhere in Chrome

A companion browser extension that brings distance-based volume to any tab — not just this site. Same camera-driven idea as the Sound page, applied across your whole browser.

OtoCorrect Extend · In Development

Distance-based volume for Chrome

OtoCorrect Extend will watch your camera in the background and gently turn the volume of whatever's playing — YouTube, Spotify Web, a video call — up or down as you move closer to or farther from your screen. We're putting the finishing touches on it now.

Free · Manifest V3 · Works fully offline · Nothing from your camera ever leaves your device.

1

Follows you automatically

A lightweight offscreen camera loop estimates your distance roughly every 100ms and smoothly eases the volume to match — no need to touch a slider.

2

Works on almost any site

Covers plain <audio>/<video> elements as well as sites that generate sound through the Web Audio API, like games and browser-based synths.

3

Private by design

Camera frames are analyzed locally and never recorded or uploaded. The extension only ever adjusts playback volume inside your Chrome tabs.

Desktop App

OtoCorrect for your computer

A native app for Windows and Mac that brings distance-based volume to your whole computer — every app, not just a browser tab.

Windows

v1.0.0

Runs quietly in your system tray and adjusts your system volume as you move closer to or farther from your screen.

Download for Windows

macOS

In Development

Lives in your menu bar and adjusts your system volume as you move closer to or farther from your screen.

How it works

Using the app, step by step

1

Open the app

OtoCorrect adds a small "oto" icon to your menu bar (Mac) or system tray (Windows) — no desktop window to manage, it just lives quietly up there.

2

Click it, hit Start Monitoring

A small menu drops down. Click Start Monitoring to begin the camera-to-volume loop in the background — nothing else on your screen changes.

3

Allow camera access

Your OS will ask permission the first time — allow it. Nothing from the camera is ever recorded or sent anywhere; it's only used locally to estimate distance.

4

Watch it update in real time

Open the live camera preview to see the detected face box plus the current distance and volume, updating continuously as you move — the same numbers driving your volume behind the scenes.
