Alright Kester, thanks :) I'm a Radio Amateur, btw, so I know about
the square attenuation (r*r) of waves with distance from the source.

I should have guessed it applies to sound waves as well :)

I'll bug the list with some more questions later. I'm already as far
as having SDL running in the gameengine and outputting a sawtooth.

If that isn't something! ;)
