MP3 to MIDI

MP3 to MIDI Converter 

Convert audio recordings into editable MIDI files using AI — no software to install, works entirely in the browser.

How It Works 

1. Upload an MP3, WAV, or M4A file (up to 10 MB free, up to 50 MB on paid plans)

2. AI transcription — a deep learning model detects pitch, timing, velocity, and rhythm from the audio waveform

3. Preview the MIDI output directly in the browser

4. Download a standard Type 1 .mid file ready for Ableton, FL Studio, Logic Pro, or any DAW Key Features
