Press Escape to cancel while recording or transcribing. Leaving this page stops the microphone and releases its audio resources.
Check the local transcription
The browser converts the microphone signal into notation with the same local transcription and engraving engines used by the editor.
Correct musical details
Play the result, download MusicXML, or continue in the editor to correct rhythm, pitch spelling, key, time signature, and layout.
What to verify
- Pitch and octave, especially after large leaps or very soft notes
- Rhythm and bar placement when the hummed pulse was flexible
- Key signature, time signature, rests, ties, and final enharmonic spelling
Common questions
Is my microphone recording uploaded?
No. Capture, resampling, transcription, engraving, and preview all run in this browser. The tool does not send audio or score content to an API.
Does hum-to-score use AI Tokens?
No. It uses the local NotationAI transcription engine and deterministic score pipeline. It does not call a hosted model and has zero Token cost.
Why did it miss notes or rhythms?
Automatic melody transcription is an editable starting point. Results improve with one voice, a quiet room, clear note changes, steady timing, and a recording between 2 and 30 seconds.
