What is voice to MIDI?
Voice to MIDI transcribes a sung or spoken vocal line into MIDI notes, translating the pitch of your voice into notes any instrument can play. Sing a melody, a harmony part, or a topline idea and get editable notes instead of a fixed vocal take.
Since the voice is naturally monophonic, a clean sung line transcribes with high accuracy. It is a fast way to sketch toplines, double a vocal with a synth, or hand a melody to a bandmate as notation rather than an audio clip.
How it works
Record or upload your voice
Upload an MP3 or WAV of your singing or a vocal melody. Sing one clear line at a time for the most accurate transcription. No account needed to convert and preview.
Preview and fine-tune
Hear your voice mapped onto a piano roll, compare it to the recording, and enable pitch bends or adjust sensitivity to capture slides and soft notes.
Download MIDI or sheet music
Download the MIDI, fix any wrong notes on the roll, or export sheet music as MusicXML/PDF for MuseScore, Sibelius, or printing.

Highlights
Sing the melody
Turn a vocal take into notes without playing an instrument.
Keep expression
Enable pitch bends to preserve slides and vibrato from your performance.
Topline to score
Export MIDI or sheet music to arrange the idea or share it as notation.
Getting the cleanest vocal transcription
- Sing a single, clear melodic line — one note at a time — rather than harmonies or overlapping parts.
- Record in a quiet space; background noise and reverb add stray notes to the transcription.
- Enable pitch bends so scoops, slides, and vibrato in your voice are captured instead of flattened.
- Hum or sing on a steady vowel ("la", "da") for cleaner note onsets than breathy or whispered singing.
Frequently asked questions
How do I convert my voice to MIDI?
Upload a recording of your singing or humming as MP3 or WAV, let the AI transcribe the melody, preview it on the piano roll, and download the MIDI. No install required.
Is voice to MIDI the same as humming to MIDI?
They use the same transcription — voice to MIDI covers singing and vocal melodies broadly, while humming to MIDI is tuned for a hummed tune. Both turn a single vocal line into editable notes.
Is the voice to MIDI converter free?
Yes. Conversion and browser preview are free with no account required. Signing in saves results to your history and unlocks editing and sheet music export.
Why are there extra or wrong notes?
Breath noise, reverb, vibrato, or overlapping harmonies can be misread as notes. Record cleanly, enable pitch bends, and use the built-in editor to correct the few that slip through.
