A SINGLE VOCAL PART

What does this vocal MIDI converter handle?

This page is for one clear vocal or other single-voice recording. Choose one MP3, WAV, FLAC, M4A, or OGG file; the shared local Web Audio pitch tracker analyzes it in your browser and creates one standard .mid download. The file is processed on your device and is not uploaded.

PREPARE THE SOURCE

How should I prepare vocals for MIDI conversion?

Remove reverb: export the vocal as dry as your mix allows.
Mute harmony: leave the part you want to convert on its own.
Export one track: avoid a full mix when you need a readable melody line.

WHAT TO EXPECT

Why can a vocal MIDI result need editing?

A vocal recording contains pitch movement, breath, consonants, reverb, and overlapping parts. A clean single voice gives the tracker a clearer signal; reverb or layered harmony can add competing pitch information. Treat the downloaded MIDI as editable note data and listen back before arranging it.

LOCAL TEST NOTES

What was checked on this page?

Each line below records one local run with known note fixtures. The input note names and MIDI numbers are the generated reference; the output note-on events are read from the downloaded MIDI file.

Single voice: input known-clean.wav was C4 (60), D4 (62), E4 (64), G4 (67). Downloaded known-clean.mid contained 4 MIDI note-on events: C4 (60), D4 (62), E4 (64), G4 (67). Exact ordered matches: 4/4; no mismatched position was observed.
Reverb: input known-reverb.wav was the same C4 (60), D4 (62), E4 (64), G4 (67) sequence with the generated echo effect. Downloaded known-reverb.mid contained 5 MIDI note-on events: C4 (60), D4 (62), F#4 (66), C2 (36), G4 (67). Exact ordered matches: 2/4; the first mismatch was output note 3, F#4 instead of input note 3, E4. The C2 low-frequency event and extra note remained, so this result was still messy.
Layered harmony: input known-harmony.wav mixed lead C4 (60), D4 (62), E4 (64), G4 (67) with a second line E4 (64), F4 (65), G4 (67), A#4 (70). Downloaded known-harmony.mid contained 4 MIDI note-on events: C2 (36), E4 (64), C2 (36), D#2 (39). Exact ordered matches to the lead line: 0/4; the first mismatch was output note 1, C2 instead of input note 1, C4, and the layered result remained messy.

SAME INTENT, ONE PAGE

Voice to MIDI, singing to MIDI, and convert vocals to MIDI.

These phrases describe the same focused workflow here: choose a vocal recording, let the browser read its pitch movement, and download MIDI note data. This page keeps the input boundary clear instead of opening separate pages for each wording.

NEXT STEP

Where can I take the MIDI file?

Use Audio to MIDI for a broader audio input page, or open MIDI to Sheet Music to render an existing MIDI file as notation in the browser.

VOCAL MIDI FAQ

Can I use this as a voice to MIDI converter?

Yes. A voice to MIDI run starts with one local vocal recording and ends with a standard .mid download. For a singing to MIDI workflow, isolate the voice you want to read before choosing the file.

Does convert vocals to MIDI handle a full harmony stack?

It can read a file containing overlapping voices, but the page is designed around one clear vocal part. To convert vocals to MIDI with a cleaner first pass, mute the harmony tracks and export the target vocal alone.
