[sdiy] saw vs ramp, audible?

[Chris McDowell]

Ah when I say play around with this, I mean Donald's phase shifted harmonics business. I wanna whip up various "not squares" and listen to them. I could do this in C but I bet someone here has a better idea. 

Cheers,
Chris

Then get a friend to play them out at random whilst you sit very still with your eyes closed listening carefully.

All of which may or may not add phase shifts, non-linearity, filtering, etc.  And if you move your head even the slightest bit relative to speakers in anything other than an anechoic room you're going to hear a significant change in the timbre due to the multipath reflections with something as broadband as a sawtooth tone.
