Voice input, explained

Use one clear pitched voice

01

Good input

Solo humming, a single sung melody, whistling, or a clean a cappella line gives the detector one prominent pitch to follow.

02

Output

You get one standard .mid file containing detected notes, note timing, and velocity. The result is editable in a DAW or notation editor.

03

Not stem separation

This vocal to MIDI page does not isolate a singer from a finished song. Instruments, backing vocals, reverb, and noise can become missed or extra notes.

04

No lyric conversion

MIDI stores performance events rather than words or recorded vocal tone. The downloaded file will not contain lyrics or the singer's timbre.

FAQ

Voice and vocals to MIDI

Can I turn humming into MIDI?

Yes. Record or upload one clear humming line. Steady notes with little background noise are easier to inspect and edit than a full mix.

Does this vocals to MIDI tool separate a singer from music?

No. It analyzes the combined audio it receives. Isolate the vocal before using this page if the source also contains instruments or backing vocals.

Is this voice to MIDI converter free?

Yes. It runs in the browser without an account. The page does not ask you to buy credits before downloading the generated MIDI file.

Does the recording leave my device?

No. The selected audio is decoded and analyzed in your browser. This page does not upload it to the site.

Why does a sung note become several MIDI notes?

Vibrato, consonants, breath noise, accompaniment, and room reflections can create changing pitch evidence. Use a drier solo take, then merge or trim note events in your MIDI editor.
