[sdiy] Harmonic bandwidth

I was under the impression that this subject has been proven mathematically, that
is, that as long as the phase of each harmonic is constant relative to the other
harmonics that there is no difference in the timbre regardless of the exact phase
angles.  I'm not really a math heavy, so I don't know if such a proof exists.

It seems we're diving into a rather subjective hole again with this.  I suppose it
could be argued that I don't hear a difference because I'm old and could be deaf in
the upper range?  My opinion is that using tools like Cool Edit and Audacity to do
these experiments is not optimum and could be flawed.  It's also difficult to
compare our experiences because of wholly different audio systems as well as
different hearing abilities.  And I'll throw in the use of MP3 compression as a
further corruption of the data that could add to the confusion.
