  • A track per instrument — melody, bass, keys and drums land on separate MIDI tracks with sensible instrument presets
  • Standard .mid file — opens in every DAW and notation app — FL Studio, Ableton, Logic, MuseScore, GarageBand
  • Any audio source — MP3, WAV, M4A and other formats, a direct link, or a track from your Homiwork music

How to Convert Audio to MIDI

  2. Or pick a track from your Homiwork music — your archive is one click away.
  3. Press “Convert to MIDI” — AI transcription takes a minute or two.
  4. Download the .mid file from your archive and open it in your DAW.

Why Convert MP3 to MIDI?

MIDI is editable music: instead of a frozen recording you get the notes themselves, ready to re-voice with any synth or sample library. Producers convert audio to MIDI to borrow a chord progression, remake a melody with a different sound, fix a timing wobble, or print sheet music from a recording. AI transcription listens to the actual mix and estimates each note's pitch and velocity — best results come from clear, well-separated recordings; dense walls of sound transcribe more roughly. The output is a standard multi-track MIDI file, so it drops straight into any production workflow.

Frequently Asked Questions

Is the audio to MIDI converter free?

Yes. New users get starter energy points — one conversion costs a few points.

How accurate is the transcription?

Clean melodic recordings convert very well. Dense mixes with heavy effects are harder — expect a good sketch you can polish in your DAW rather than a perfect score.

Does it keep the song's tempo?

Note timings are preserved exactly as performed. The file uses a fixed tempo grid, so beats may not align to bars until you set the project tempo.

Which files can I upload?

MP3, WAV, M4A, OGG and FLAC up to 8 minutes long, plus any track from your Homiwork music.
