MOTM

I posted the mp3 to the Files section.  There is some warble from 
the noise reduction algorithm, but you get the essential character.  
Woody, but nasal.  Moving the transducer produced differing timbres 
as you would expect.  This one is representative.  A better 
transducer might work better.  ANd amplifying the signal more might 
also make a difference.

All in all interesting, but not what I expected.  Needs more 
fiddling, which I will do this weekend.
