1. RE: Lower WAV pitch problem
Dan:
You maybe creating a harmonic of the original.
Try changing the original by something other
than one half or double which would create a
harmonic.

Dan:
May I help you by looking at your code to see where it went wrong?

Dan:
The problem was not "a bunch of harmonics", but rather that each harmonic
was exactly at a frequency *twice* of the previous one.

So, it works without changing the pitch... by changing the pitch a big
amount!

Right, a C in one octave becomes a C an octave lower.

Of course, I know that, but changing the pitch one octave *is* changing the
pitch.
