Well I finally had a few minutes to play around and alas, the results aren’t worth really publishing. Here’s why:
With pure tones, there’s not much difference between a sine wave, a triangle wave, a square wave and a sawtooth wave.
The top is a sine wave, and middle and bottom are types of triangle waves.

The difference is harshness and brightness and such it’s not a tremendous amount of difference between the three.
But, in the process, I _did_ acquire some fun freeware for sound generation and stuff to play around with as I went the “long way” around to the answer… as I wanted to see could make the EXACT forms as shown in the ‘gif.
And I can; I can draw them in audacity after starting with a sine or square wave… I can ‘scan’ them using an ancient image to sound converter called… image to sound… [converts 24 bit BMP to sound]… or mathematically if I get the formulas. [I forgot where now].
But the site I pointed you to will show that, as the forms are regular, there’s not a WHOLE lot of difference between them.
You’re welcome smile emoticon The thing about methodically finding answers to questions (some call it scientific but to me it’s just being thorough, as I like to find a number of solutions to a single problem, not just one) is that you always end up with SOME kind of really good answer.
And often the really good answer isn’t what’s hoped for, but it’s thorough. But what I _really_ like about going through things methodolically and attacking from a few angles is that I always end up with a few interesting tools I can use in the future for other stuff smile emoticon
