-====== ArmA 2 Sound ======
-If there are 3 parameters, then from second (volume in dB) is used for maximum distance calculation, max. distance is emitter distance from listener where sound from this emitter is not audible.
-When in cfg are four parameters, then 4 parameter is distance in meters, and second parameter (volume in dB) is ignored - is recalculated based on max distance.
-dB == 1000m
-is recalculated based on max distance
-What max distance is this - related to view distance?
-Sample volume is recalculated, volume is derived from distance ( where 0dB = 1000m ), there is no "real" difference between these to entries.
-Distance == view distance.
-Some more good information - details about new class Sounds of cfgVehicles.
-  * frequency range is [0.6, inf] but usable range is somewhere about 1 that's [0.8, 1.2]
-  * randomizer = small random number unique for each vehicle, range [0, 1]
-  * angular velocity - but this controller is not much usable, because values are discrete, not smooth, so in frame N it should be 0 and in frame N+1 it should be 2
-  * factor - linear interpolation between A and B based on x, value = A + (B - A) *x, trick to get peak is using min{ X factor [A, B], X factor [B, A] }
-====== Example config ======
-Here is example helicopter engine / rotor sound config.

-EngineLowOut {"A10_Ext_Engine_Low", 45.2387, 1, 700}
-This sound you should hear last, its the rumble or 'jet wash' you get when an aircraft makes as it gets closer to your position.
-EngineHighOut {"A10_Ext_Engine_High", 25.2387, 1, 1100}
-This is the 'throttle' sound, the sound activates when you apply acceleration as well as sounding at other (from what I can tell) drastic stick movements ? Had to define when you start to hear it but somewhere between the two others gives me the best results during a flyby.
-ForsageOut {"A10_Ext_Engine_Idle", 40.2387, 1, 4000}
-This is the main engine sound, this kicks in as the the engine_start sound is fading out and plays a constant loop until you stop the engine or it gets destroyed.
-{"V_55", 1.0, 0.5, 900};\\
-.0 is volume at source\\
-.5 is pitch 0.0 being same as orginal sample\\
-is volume over distance (how far it can be heard)
