[sdiy] Harmonic bandwidth

Ok, now I've done it.  I wrote a C program to generate 3 .wav files using double float,
one with zero starting phase values and 2 more each with different random, but constant
phase values.  The program uses 32 harmonics in the series that produces a sawtooth.  I
was careful to limit clipping and applied the same worst case attenuation value to all
three.  Each sample is several seconds long.

I most definately hear a difference in timbre.

The question is "why?".  

Surely, there is something about digital generation of waveforms.
