What InSpectro does
Your voice turns into color in real time. Lows at the bottom, highs at the top, and the stronger the harmonic, the warmer the color.
A precision engine measures how many overtones you reveal and gives you the number instantly. It's the Challenge, the score only InSpectro has.
Pitch and warm-up exercises with instant feedback, in game form. You improve without feeling judged.
A sound field to lean on and tune over, with the keyboard always at hand.
Record sound and image together, with Reverb and Delay on your voice and the spectrum in motion, to track your progress.
Opens in your phone or computer browser, instantly, with nothing to install.
More than a spectrogram
The only one to unite the spectrogram with vocal training exercises and challenges, synthesizers to create backing drones, recording with effects, and a precision engine that gives feedback instantly.
Pitch training and vocal warm-up with instant feedback, in game form. The joy of experimenting and playing with your own voice, with no pressure.
Interactive keyboard and continuous drones to create a backing and tune over it, on any note you want.
Reverb and Delay to give body and space to your voice. With headphones, you hear yourself live while you practice or record with quality.
With one click, create interactive videos with or without camera, capturing your ideas and sharing them with friends.
Plans and access
You start for free and choose access whenever you want. Two tracks: use the app on your own, or learn the method in the live lessons.

Yes. Every voice has overtones, and InSpectro shows yours. You don't need any singing experience to start seeing and measuring.
No. It works with your phone or computer's own microphone. Headphones are only recommended when you want to hear your voice live with the effects, to avoid echo.
You can start for free, choose a short pass, subscribe monthly, or buy the lifetime plan once. You can cancel the monthly subscription anytime, directly on Hotmart.
It's how you measure how many layers your voice reveals at the same time. You hold a note, shape the sound, and the score goes up. It's the core feature of InSpectro.
The app is the tool to see, measure and train on your own. The lessons (recorded Tutorial and live sessions) teach the method step by step. The two tracks complement each other.
