Made for stems and loops

WAV files usually come out of a DAW or a sample pack: a bounced stem, a loop, a single recorded part. That's exactly what audio-to-MIDI does best. Pick the instrument so the converter knows which pitch range to listen to.

Tips

  • Export dry stems when you can: reverb and delay tails can turn into extra notes.
  • For a full mix in WAV, choose Whole song instead.
  • 24-bit, 32-bit float and any sample rate are fine; the file is read as-is.

Questions

Is it free?

Converting one instrument is free and unlimited, and runs in your browser. Downloads are free too: 3 a month with a free account. Piano and whole-song mode give you a free 30-second preview; Pro converts whole files up to 15 minutes.

Will the MIDI line up with my DAW's grid?

Yes, for music with a steady beat. AnyToMIDI detects the tempo, writes it into the file and moves the first beat onto a bar line, so the notes land on your DAW's grid at the project tempo. If it reads a slow song at double speed, use the ½× button before downloading.

Is my WAV uploaded?

Not in One instrument mode: it's converted in your browser. Piano and whole-song mode send the audio to our server, which deletes it after converting.
