Is this Possible?

Is it possible to use 2 Horn sound recordings on 1 locomotive? For example, you use one horn recording for when the train is coming towards you, then when it passes you it will play the 2nd horn recording. Just like on the Leslie Horns like the RS3L, it sounds like every other RS3L, but it sounds different when your behind it.

Can someone please answer this? There are some sound experts out there.

On the current sound engine, no, this is not possible. For a system like that, sounds would need to be made directional, with a system similar to what Flight Simulator X uses, which they call sound cones. They project the sound in the direction of the cone, then, when the camera exits the area covered by the sound cone, the sound stops playing, or, often, is able to get quieter, such is the case with most planes that use sounds designed specifically for FSX instead of FS2004. When you rotate the camera around the plane, the engines will have more of a hiss from the front where the engine intakes air, then, when behind the rear, you can hear more of the combustion going on in the engine. See the video below for what I mean.

But yeah, like I said, a system like this isn't implemented in our current iteration of Train Simulator. I really wish it was, so that you can have the camera in different positions on the locomotive, yielding different sounds from the prime mover, such as standing near the front, with the prime mover sound being obstructed by the locomotive, but you are able to hear a rumble from the frame. And of course, the most important, horns with bells in different directions and occluded volumes on front facing horns from behind.
