[sdiy] Harmonic bandwidth

[Needham, Alan]

So, there seems to be agreement that the sawtooth waveform may be a bad
example, square should be worse. How about trying a triangle, this
should avoid any speaker transient issues as far as is reasonably
practicable.

Or use ONE of the "saw-spectrum" mutated waves and compare it with its
inverted form and with a copy played backwards, all should have the same
transient energy and different harmonic phases?

I find the note at the end of
http://www.silcom.com/~aludwig/Phase_audibility.htm#Three_notes article
about 200Hz and 400Hz sines to be fairly compelling, although it applies
to a special case, resulting in an identical waveform.

	Alan.
