Who uses MP3 to MIDI
Producers
Pull a melody or bass line out of a sketch, a voice memo or a sample and keep working on it in your DAW.
Learners
Slow a passage down, see which notes are played and practise them on your instrument.
Arrangers
Get a first MIDI draft of a tune, then fix the notes and re-orchestrate it for other instruments.
Full-song, multi-instrument MIDI is coming
We are working on splitting a whole song into separate MIDI tracks for each instrument. Leave your email to hear when it is ready.
Frequently asked questions
Can I convert an MP3 to MIDI here today?
Not yet. Uploads open soon. Until then you can listen to real before-and-after examples on this page and leave your email to be told when the converter goes live.
Will it be free?
Yes. Converting and previewing will be free with a daily limit, and you will not need an account.
What kind of audio works best?
A single instrument or a single voice: solo piano, guitar, a sung or hummed melody. Clean recordings without background music give the most accurate notes.
Can it turn a full song into MIDI?
A full mix with drums, bass and vocals will only give a rough draft. Separating a full song into one MIDI track per instrument is planned as a separate feature — leave your email in the section above to hear when it is ready.
Which file formats will be supported?
MP3, WAV, FLAC, M4A/AAC and OGG, up to 5 minutes and 25 MB per file.
What happens to the files I upload?
Uploaded audio and the MIDI result will be deleted automatically within 48 hours. We use them only to run the conversion.
How were the examples made?
Each example clip was converted automatically by the transcription model the converter will use (Basic Pitch), with settings for the instrument and an automatic clean-up of very short and stray notes. Nobody edited the MIDI by hand, so it shows the real quality you can expect.
