This seems like it would be a useful exercise in tone production (to record
yourself and dissect the harmonics of the tone). Where could I get ahold of
some shareware of this kind? I searched the net and found a couple of
entries, but no relevant data. If somebody has these and they ARE
shareware, could they post them on an ftp or something? It would be greatly
appreciated by many, I am sure...

Thanks,
Ryan Lowe
