Free audio to MIDI converter

Hum or sing a melody, or upload a single instrument, and NAAD Mix turns it into MIDI notes you can drop into FL Studio, Ableton, Logic or any DAW. You can also pull just the vocal or just the melody out of a full song first.

How to use it

  1. Upload your audio.
  2. Choose As is (a vocal or one instrument), Vocal only or Melody only (for full songs).
  3. Adjust sensitivity and snap to the beat, play it back, then download the MIDI file.

Why NAAD Mix

  • Turn a hummed idea into notes in seconds
  • Snap notes to the beat and set the shortest note
  • Play MIDI, audio or both to check it
  • Download a standard .mid file for any DAW

Questions

Is audio to MIDI free?

As is mode is free. Vocal only and Melody only split the song first, so they use the same daily free limits as the stem splitter. Guests get 1 free song a day, a few more after entering an email, and a free account gets up to 30 a day.

Does it work with chords?

Not yet. It follows one note at a time, so it works best on vocals, humming, bass lines and single melodies.

Can I convert a full song to MIDI?

Choose Vocal only or Melody only and NAAD Mix takes that part out of the song first, then converts it.

Which DAWs does the MIDI file work in?

All of them: FL Studio, Ableton Live, Logic Pro, GarageBand, Cubase, Studio One and more.

Can I hum a melody?

Yes. Record yourself humming on your phone and upload it with As is mode.
