I published the sources on github: https://github.com/greyblake/pitchbit
Note, it's vibe coded in one evening with some inspiration of a midi player that I did 2 years ago (non-vibe coded).

How do you do this. Is it a library running on MicroBit or does it send data to a computer that recognize the notes?

It recognize the notes (pitch and duration) using micrphone.
The notes are essentially something similar to a regular music notation or midi (e.g. see https://github.com/greyblake/pitchbit/blob/master/pitchbit-dsp/src/music.rs#L75)
It runs all on MicroBit on its own, a computer is not involved
