- Convert, preview the detected notes, and download the `.mid` file.

What works best
One file at a time, up to 50 MB and 5 minutes. Clear solo melodies work better than drums, heavy effects, or a dense full mix. The result is a starting point you can edit in a DAW or notation app.
FAQ
MP3 to MIDI questions
Can I convert audio to MIDI without uploading it?
Yes. This page processes the audio in your browser and does not send the file to a server.
Can I convert WAV to MIDI?
Yes. WAV, MP3, M4A, FLAC, and OGG are accepted when your browser can decode the file.
Can I turn a voice recording into MIDI?
Yes. Record a clear sung or hummed melody, then adjust the detection controls before downloading the MIDI result.
Why do some notes need editing?
Audio contains sound, while MIDI contains note events. Background noise, overlapping instruments, reverb, and dense chords can produce extra or missing notes.
