Hey! I'm trying to figure out which files are activated from certain angles with the new 3d sound design in FSX. For example: The F-18 sounds have titles like 'xFA18_an11, xFA18_an21, xFA18_bn11, and xFA18_bn21". Which sounds correspond to right, left, forward, aft? I'm trying to replace the sound files but i'm having very little luck with trial and error.  Any help would be greatly appreciated. Thanks!
