[sdiy] Additive Synthesis - phase shifts important??

[cheater cheater]

Heheh, yeah.
So, to paraphrase what I posted earlier:

I'm pretty sure that even a constant phase-shift will give you a
noticable change in the timbre.

But even then, consider the fact that the signal will overdrive
differently. Just put a square wave through a rectifier - you still
get a square wave. If you put the square wave shifted by Pi/2 (so an
'arc sin wave') you will get something very different, that would look
more like an exponentialized trapezoid wave.

Now that everyone knows I meant half-wave rectification, this example
should be clear as water 8)
