I've thought about this too. Unfortunatly I don't have a digitiser.
In anycase it should not be too hard to get the data you need. One
way might be to contact the manufaturer of your digitizer.
Basically what you will need to do is capture the data comming in on
whatever port they're using and then run some math on it. Are you
knowlegable about Fourie Transforms and finite series? If not, look
into signal processing. Also look into signal processing chips such
as TI's TMS 320XX (ie: 32010/20/25C...) series, the documentation for
which goes into detail on the "how to's" involved.
If you get this working let me know as I'd be interested in seeing it.
Of course, I don't see it as being very practicle, as I'm not going to
give up the convience of a walkman size tuner for the boat-anchor that
sits on my desk :^).
WHAT WOULD BE REALLY USEFUL AND PROBABLY MARKETABLE WOULD BE A VERSION
OF THIS WHICH WOULD SHOW THE OVERTONES AS A SET A WAVE FORMS RATHER THAN
JUST ONE BIG CONGLOMORATION. This would be immensly useful in adjusting
the intonation, and would be of interest to commercial music repair shops.
Good Luck,
Wade.
