"Your ears can fool you. Physics can't."
— SonaLab
What We Believe
Singing has long been treated as mysticism — feel it, intuit it, or be born with it. We believe in another path: the voice is a physical phenomenon, and it can be measured, understood, and mastered.
What We Build
SonaLab turns professional acoustic analysis — spectrum, formants, NAQ, Singing Power Ratio — into real-time charts and health scores anyone can read, with a built-in AI assistant to interpret the data and point your practice in the right direction.
All audio is processed on your device in real time: never uploaded, never stored. Your voice belongs to you.
What about the built-in AI assistant — why does it ask for your own LLM API key? All analysis and symptom detection runs in real time on your Mac. The only things sent to the model are the resulting parameters — health scores, symptom statistics, pitch range — plus our interpretation rules. The model's job is to organize those numbers into advice you can read and act on; it never "listens to" your voice.
Your original recordings are never part of that request — they never leave your device or reach any LLM. Your API key is stored only in your device's keychain, and requests go directly from your Mac to the model provider, never through SonaLab's servers. You can even choose a local open-source model in Settings and keep the entire pipeline offline.
Where We Stand
SonaLab won't replace voice teachers — just like a calculator doesn't replace math teachers.
What we build is the "kilogram" — an objective, stable standard of measurement. It tells you what's happening in your voice, giving progress a scale and practice a direction; the method and the path remain yours and your teacher's.
That is exactly why we salute every great voice teacher out there, and sincerely recommend to every student: find a vocal teacher — the tool gives you the scale, but a great teacher gives you the path.
