I went back and read some of my notes off of g4guo's web site, and one of
them was:
"The waveform uses clipping to reduce the peak to mean ratio, followed by
filtering. Each tone starts at a different phase offset to try to reduce
the crest factor. The phase offsets were calculated using Newman Phase
Generation."
I remember looking-up Newman Phase Generation, and found mostly mathematics
buried in greek and egyption symbols and promptly forgot about it. I did
another search now, and found:
http://www.stanford.edu/~boyd/papers/pdf/multitone_low_crest.pdf
Which is actually readable by an undergraduate who hid in the back during
calculus...
Google search finds a bunch of poop:

have fun,
