But it depends on the frequency pattern, no? So we'd need to
analyze the spectrum ... time to use libfftw3.  :-)

I don't see why adding these values to the sound config
should be such a problem. Don't we specify animation
parameters to the smallest detail? Why should sound be
different?

OTOH, I would support global default values <max-dist> and
<reference-dist> in preferences.xml, which an aircraft
could override. And finally, every sound definition can
still define its own values like before.

JFTR: The bo105 sets these values since a while.  :-P
