Vocal Range Finder — PitchHighway

About

Discover your vocal range and voice type in about 60 seconds — right in your browser.

Sing or hum into your microphone and Vocal Range Finder guides you through three quick steps:

1. Warm up
2. Find your lowest comfortable note
3. Find your highest comfortable note

You'll get:
• Your range in scientific pitch notation (e.g. C3–C5)
• The span in semitones and octaves
• Your closest voice type — Soprano, Mezzo-Soprano, Alto, Tenor, Baritone, or Bass

100% PRIVATE. Pitch detection runs entirely on your device using on-device AI (the SwiftF0 model via ONNX Runtime + WebAssembly). Your microphone audio is never recorded, uploaded, or sent anywhere. The extension makes no network requests.

No sign-up. No account. Completely free.

Tips for the most accurate result: use headphones in a quiet room and warm your voice up first.
