Song to MIDI Converter

Turning a whole song into MIDI is the dream — and also the hard case, because a full mix layers vocals, drums, bass and instruments on top of each other. AI transcription pulls out the most prominent pitches, which is perfect for grabbing a lead melody, a hook, or a recognizable line to build on.

What stands out in your recording?

Choose a starting profile. It changes note detection, pitch bends, and cleanup; Advanced settings remain editable.

Drop an audio file to convert to MIDI

MP3 · WAV · FLAC · M4A · OGG · AAC · MP4 · WebM · up to 100 MB — stays on your device

MP4 and WebM need an audio track your browser can read. If a video does not open, export its audio as MP3 or WAV. For files over 100 MB, choose a shorter recording or export just the audio.

Have a melody in mind?

Record one voice or instrument for up to 60 seconds. Listen before converting.

Free and processed on-device · powered by Spotify's open-source Basic Pitch model.

Drop a song into the song to MIDI converter and it transcribes the audio on your device. For the cleanest result, an isolated stem (just the vocal or just the piano) will always beat a dense full mix — but a clear single-instrument song works well as-is.

Grab the melody fast

Get the main line of a song into MIDI so you can study it, transpose it, or re-harmonize it in your DAW.

Stem tip for accuracy

If a full mix is muddy, separate a stem first (e.g. an a-cappella or instrumental) and convert that — far cleaner notes.

Unlimited and free

No paywall, no daily cap — convert as many songs as you want, with nothing uploaded.

Song to MIDI — FAQ

Can a song to MIDI converter handle vocals and drums?

You can try it, and the tool will transcribe the most prominent pitches, but dense mixes are inherently hard. For a clean part, convert an isolated stem instead of the full mix.

Is converting a copyrighted song to MIDI allowed?

Transcribing for personal practice or study is common, but distributing MIDI of copyrighted music may not be. Because everything stays in your browser, your conversion is private to you.

How do I get a better melody line?

Use a cleaner or more isolated recording, and raise the note-confidence threshold in Advanced settings so only the strongest pitches become notes.
