[sdiy] Harmonic bandwidth

[Mike]

This is a bit wierd: I downloaded all 3 samples and loaded them into
Audacity. Unless we have a player fluke here, I can't hear any real
difference between the first 2 that can't be accounted for by level, but to
me the third one seems quite timbrally different.

I'm wondering if there is some artifact in the program first of all. I need
to brush up my CSound and try again.

I don't agree with the guy's terminology - to me a harmonic is a
mathematical definition - an integal multiple of the fundamental. I think
'Partial' is the better term for what he is doing
