How to convert MP3 to MIDI in 3 steps
Turning an MP3 into MIDI takes less than a minute — here is the whole flow.
1
Add your audio
Upload an MP3, WAV, FLAC or M4A file, or pick a song or stem you already have. Any audio works — the converter just needs a sound to read.
2
Choose your engine
Use the Traditional engine for fast, note-for-note transcription, or the AI engine for cleaner results on full songs. Then press Convert.
3
Edit and download
Your .mid opens in the piano-roll editor. Tweak notes, tempo or key, then export the MIDI file or save it to your library.

Two ways to convert audio to MIDI
Pick the engine that fits your audio — both turn sound into an editable MIDI file.
Traditional engine
Built on an open-source pitch-detection model, the traditional converter reads your audio note by note. It is fast, runs on anything you upload, and is the best choice for solo instruments, melodies and single stems.
AI engine
The AI engine is tuned for full, layered songs. It interprets the mix to produce a cleaner, multi-track MIDI where a straight transcription of a busy track would be too cluttered.
What can this converter turn into MIDI?

Loved by producers and hobbyists
Turn any audio into editable MIDI in seconds.
I hum a bassline into my phone, convert it to MIDI here, and reassign it to any instrument. Fastest way I've found to get an idea out of my head.

I turn reference tracks into MIDI to learn the chords, then rebuild them in my own style. The AI engine catches harmonies the cheaper tools always miss.

Recorded a riff, dropped the MP3 in, and had an editable .mid in seconds. Being able to fix a couple of stray notes afterward sold me.
