Re: [LAD] sound dissipation in air - formulas and filters? (Maitland)

 true, for this particular case it would do (and that's what i'm using
 atm). but i have this idea for a plugin that takes actual mic distance,
 temperature, humidity and desired distance as parameters and will do
 something that is reasonably correct (not taking into account sound
 diffraction or reflection at temperature boundary layers, obviously).
 would be kind of cool, but i need to get a deeper understanding of the
 physics involved... especially the dependance on humidity is a very
 tricky and quite non-linear issue.

 fons is probably right that it doesn't make all that much of a
 difference, but since such a plugin could be a nice learning tool for
 sound engineers, i'd want it to be as precise as reasonably possible.

This sounds like a really interesting project to me, and I wish you
all the best in completing it!  Aside from being a nice learning tool,
I'm sure it will be a *very* nice creative tool, as well.

I can't wait to hear what it sounds like to modulate humidity with a sine wave!

:-D the effect will be very subtle indeed. gives a whole new ring to the
term vaporware.

while we're at it, the in and out ports should probably simulate
corrosion after prolonged exposure to humidities  .8 ... patches welcome.
