How it works
Record a melody
One voice or instrument at a time works best - singing, humming, whistling, a lead guitar or flute line.
See the notes
The pitch is tracked every 12 ms and grouped into notes on a piano roll. Preview it against the original.
Download MIDI
Shift octaves, quantize to the grid at your tempo, and download a standard .mid file for any DAW.
How to convert audio to MIDI
Turn a sung, hummed, whistled or played melody into MIDI notes you can edit in any DAW. This free audio to MIDI converter (also works as MP3 to MIDI or WAV to MIDI) is built for single melody lines.
Record or pick a melody
Use a recording with one note at a time - a voice memo of you humming, a whistled tune, a lead guitar, flute or violin line. Drop the MP3, WAV or M4A onto the box.
See the notes
The melody is tracked and drawn on a piano roll. The note count and range appear beside it.
Check it by ear
Press Play MIDI to hear the notes, or MIDI + original to hear them over your recording.
Tidy it up
Use Octave to move the notes up or down, set the Tempo (BPM) of your project, and choose a Quantize grid (1/16, 1/8 or 1/4 notes) to snap the timing.
Download the .mid file
Press Download .mid and drag it onto an instrument track in FL Studio, Ableton Live, Logic, GarageBand, Cubase, Reaper or MuseScore.
Frequently asked questions
Does it work on full songs or chords?
It's built for single melody lines - one note at a time. On full mixes or chords it will follow whatever is loudest, which usually isn't useful. For a song's melody, use an isolated vocal or a clean recording of the tune.
Which DAWs can open the file?
All of them - it's a Standard MIDI File (.mid): FL Studio, Ableton Live, Logic, GarageBand, Cubase, Reaper, MuseScore and more.
Why are some notes missing or extra?
Very short notes, breathy or noisy sounds and slides are hard to pin down. Record close to the mic in a quiet room, sing clearly, and use Quantize to tidy the timing afterwards.
Is it free and private?
Free, unlimited, no sign-up - and the conversion happens in your browser, so your recording is never uploaded.
Hum it, then make it a full song
Turn your melody idea into a finished track: the Swara Sound studio's Vocal to Song builds a full band around your own recorded voice.
