MP3 to MIDI Converter
Turn any song into a clean, editable MIDI file — one track per instrument, full length.
MP3 to MIDI Converter — Turn Any Song Into MIDI
Upload a song and get back a real MIDI file: the notes themselves, not just the sound. This audio to MIDI converter listens to the full mix, finds each instrument on its own — voice, drums, bass, keys, guitars, synths — and writes every part as a separate track. Before you download anything, you see the result as a piano roll and hear it played back, so you know exactly what you’re getting.
MP3, WAV, M4A, FLAC, and videos with music all work. Full songs, not 30-second clips. Free to try, straight in the browser, with nothing to install.
How to convert MP3 to MIDI
- Upload your audio — an MP3, WAV, or any common format, or a video with music in it.
- Wait a moment while it’s transcribed. A one-minute song takes about fifteen seconds.
- Check the piano roll, press play, and download your .mid file — every transcription arrives with its piano roll and audio preview already rendered.
You also get MusicXML — open it in MuseScore or any notation app and the transcription becomes sheet music.
Why the results are actually usable
Most converters run a model on the raw mix and hand you the output — a single garbled piano track full of ghost notes. This one works differently:
- One track per instrument. Drums land on a real drum track, the bassline is a bassline, the vocal melody is its own line. Mute what you don’t need in your DAW.
- Notes land on the beat. The tempo is detected and notes are snapped to the grid, so the file drops cleanly into Ableton, Logic, FL Studio, or GarageBand at the right BPM. When a performance is too loose to snap honestly, it is kept as played rather than mangled.
- Proof before download. Every transcription comes with a piano-roll picture and a rendered audio preview, automatically — you see the notes and hear the result up front, no downloading a mystery file to find out.
What people convert
- Songs to MIDI — pull the parts out of a track to remix, reharmonize, or learn from.
- Hummed or sung melodies — sing an idea, get the notes.
- A single instrument — a guitar riff, a piano take, a bassline, straight to editable notes.
- WAV stems and bounces — recover MIDI from a mixdown when the project file is long gone.
FAQ
How do I convert MP3 to MIDI? Upload the MP3, wait a few seconds for the transcription, check the piano roll, then download the .mid file. Nothing to install and no DAW needed — it runs in the browser.
Can I convert WAV to MIDI? Yes. WAV, M4A, FLAC and AIFF convert exactly like MP3, and lossless files usually transcribe a little more cleanly.
Can I convert a YouTube video to MIDI? Save the video or its audio to your computer first, then upload the file — video soundtracks convert the same way audio does.
What is a MIDI file? A MIDI file stores the notes of a piece — which pitch, when, how long, how loud, on which instrument — rather than the recorded sound. That’s what makes it editable: change the melody, swap instruments, fix timing, in any music software.
How accurate is it? Clear parts transcribe very well: basslines, drums, lead melodies, piano. Dense pads and heavily layered walls of sound come back approximate — a strong starting point to edit rather than a perfect score. The preview shows you honestly before you download.
Does it handle drums? Yes, properly — drum hits are written as real percussion events (kick, snare, hi-hat) on the drum channel, not fake piano notes.
Can I get sheet music too? Yes. Every conversion includes a MusicXML file that opens as notation in MuseScore, Finale, Sibelius, or Dorico.
Is there a length limit? Full songs are fine. No 30-second cap.
Is it free? It is free to try in the browser, with no setup and no plugin to install.
Can I go the other way and turn a MIDI file back into audio? Yes — MIDI to MP3 Converter performs a .mid through a General MIDI soundfont and hands you an MP3 or WAV. Useful for hearing a transcription from this app once you have edited it.
How is this different from the Stem Splitter? Stem Splitter separates a recording into isolated audio stems — you still get audio, just unmixed. This converter goes further and turns the performance into notes you can edit, retime, and reassign to any instrument. Use Stem Splitter when you want the original sound on its own; use this when you want the notes.
