Turn Your Singing Voice Into Printable Notes Directly in the Browser

Turn your singing voice into printable notes (in the browser)

I built a browser tool that converts your singing voice into printable musical notation instantly. By adjusting settings like pitch tolerance and re-attack sensitivity, you can capture repeated notes or long held tones accurately. Just remember to use headphones so the click track doesn't bleed into your microphone, ensuring the noise gate filters out background sounds effectively.

Sing repeated notes on separate syllables like ta-ta and it works; sing them legato on one vowel and nothing in the signal distinguishes them from a held note.

    Your server is sending a header that switches this feature off for the whole page. Look for Permissions-Policy: microphone=() in your host config and allow microphone=(self) instead.

    Despite allowing microphone.

    Disclosure: it is a favor for my little sister.

    I made it for her in 5min without much testing on recognition accuracy. Which was enough to blow her mind ;)

    Given your feedback, i might do another loop on this.
