How to convert audio to MIDI
Upload your audio
Drop in an MP3 or WAV — a hummed melody, a guitar line, a piano riff, or any single-note recording.
AI detects the notes
Pitch detection analyzes the recording and transcribes it into MIDI notes with timing.
Download the MIDI
Export a standard .mid file and open it in any DAW to edit, re-instrument, or build on it.
What you can do with it
Turn a hummed idea into editable notes, transcribe a melody you can't pick out by ear, swap an instrument's sound by re-triggering the MIDI, build backing tracks, or sketch a song to finish in your DAW. It works best on monophonic audio — one note at a time.
Audio to MIDI FAQ
Is the audio to MIDI converter free?
Yes — convert audio to MIDI for free. Sign in to save your files.
What audio formats can I upload?
MP3 and WAV. A clean, single-instrument or solo-vocal recording converts most accurately.
How does audio to MIDI conversion work?
It uses pitch detection to find the fundamental frequency over time and transcribes each detected pitch into a timed MIDI note.
Does it work on full songs or chords (polyphonic audio)?
It works best on monophonic audio — one note at a time, like a hum, melody, or solo line. Dense mixes and chords are much harder to transcribe accurately.
Can I open the MIDI in my DAW?
Yes — you get a standard .mid file that opens in Ableton, FL Studio, Logic, GarageBand, and any other DAW.
How do I get the most accurate result?
Use a clean recording of a single melody with clear pitches and minimal background noise — humming or a solo instrument works great.
