I don't think he means (exact) harmonics but partial tones (sinoidal
components of a musical tone with not neccesarily exact whole number
multiples of the base freqency).

Years ago I know "Lemur" did sinoidal tracking on a Macintosh. I think this
beast still exists...
If you don't have a Mac, still have a look at the manual so you might get
some ideas what the program should do you are looking for.
