Dear Reg:

Thanks for the info on calculating the sinusoidal components and
their relative amplitudes via Fourier analysis. It will take some
returning to my engineering math for me but I like to see if I can
still follow earlier work in his area.

You would be interested, I think, to know that when using the vowel
mirror devised by Burt Coffin I powered it with a square wave
generator/tuner. As a result, it made it a lot easier to locate the
vocal tract shapes necessary to focus individual vowels because I was
primarily working with the odd harmonics.

The one question you have not yet answered to my satisfaction is why
you are convinced that the open/close mode function of the vocal
folds will produce only a square wave. It is not true of the similar
function of the lips when played with just a trumpet mouthpiece. Or
are not speaking of only the phonated tone (or only the trumpet
mouthpiece tone).
