Mp3ToMidi

Mp3ToMidi is a free-to-try web tool that converts audio files into MIDI format using AI. It supports MP3, WAV, FLAC, and OGG files. You upload an audio file, and the tool analyzes it to detect notes, rhythms, and instruments, then outputs a MIDI file you can download instantly. No sign-up or installation required — just drag and drop.

The conversion is powered by Spotify's open-source Basic Pitch library, which provides accurate note detection even for complex chords and melodies. The tool processes files quickly — you get your MIDI in seconds. There are no watermarks or limitations on downloads. The resulting MIDI files work in any major DAW like Ableton Live, FL Studio, Logic Pro, or GarageBand. The interface is straightforward: a drag-and-drop area and a convert button.

This tool is especially useful for music producers who want to sample and remix, educators who need to create sheet music from recordings, and composers transcribing orchestral pieces. It's also handy for bedroom producers looking to quickly turn a melody idea into a MIDI file. The AI handles polyphonic audio reasonably well, though very dense mixes may have some inaccuracies. Overall, Mp3ToMidi is a practical, no-fuss converter for anyone working with MIDI.
