MIDI Converter
Online AI MIDI converter for audio, MP3, WAV, M4A, FLAC, and more
This is the general PureMIDI converter that is actually usable today. Upload MP3, WAV, M4A, FLAC, OGG, WEBM, or AAC and the AI extracts melody, chords, bass, or drum information into a standard .mid file. PDF sheet music, direct YouTube links, the online MIDI editor, and the AI MIDI generator are still waitlist features and are labeled that way.
Upload audio to generate MIDI
Start with 30-60 second single-instrument, lead melody, or clear vocal clips. The AI extracts pitch, timing, and velocity.
