Looking at the xmlsound structure... Wondering if it would be useful to extend the structure and methods to add a second property and then define a set of additonal macro operators to combine the two properties with an arithmetic/logical operation to produce a result.
One example; interior jet engine noise is a function of thrust and airspeed. It's at a max at takeoff and decreases during climbout as TAS increases; it's probably the loudest on landing when reverse thrust is applied. So one could take the rumble.wav sound file, increase volume/pitch for higher power settings and subtract some amount as a function of airspeed to arrive at a final value. Or is there a set of xml constructs to do the same?
