Getting the cleanest music transcription
- A single, clear lead line transcribes far better than a full mix — isolate the melody or use a stem if you have one.
- Full songs with drums, bass, and layered instruments will produce extra notes; expect to clean them up in the editor.
- Trim intros, outros, and silence so detection focuses on the musical content.
- AI transcription is a starting draft — the editor is where you turn it into a usable score.
Frequently asked questions
Can I convert any music to MIDI?
You can transcribe any MP3 or WAV, but accuracy depends on the material. Clear, monophonic melodies come out cleanest; dense, fully-produced songs will contain extra notes you can fix in the editor.
What formats are supported?
MP3 and WAV uploads up to 50 MB. For the best transcription, start from the cleanest source you have.
Is the music to MIDI converter free?
Yes. Conversion and browser preview are free with no account required. Signing in saves results to your history and unlocks editing and sheet music export.
How is the transcription done?
By Spotify's open-source Basic Pitch model, which detects note pitch and timing from the audio. You can fine-tune parameters and re-transcribe until it sounds right.
