Hum to MIDI
Hum or play a melody: it becomes MIDI notes.
…
How it works
- It works with one voice or instrument at a time (a melody), not chords or full songs.
- Notes are detected with the YIN algorithm and joined when they stay steady for at least 80 ms.
- Quantize lines the notes up to the grid of the tempo at the top.
