So, if I understand correctly, a bunch of wave files plus a config file will work in FSX or FS2004, right? So there's no concern as to which of the two I am running(?)
That's correct. However, some aspects in the sound department have been changed in FSX, I think it's called 360 degree sound-panning; you can hear it when you fly an FSX default a/c for example when you change the angles of the exterior view.
FS9 doesn't have this extra trick up its sleeve. Needless to say due to these additional sound aspects in FSX, soundsets for FSX have become somewhat more complicated to make. Perhaps this is the reason why during all the years FSX has been on the market now, very few freeware soundsets have been created for FSX.
In a nutshell, all FS9 soundsets should work in FSX. Whether "native" FSX soundsets work in FS9 I don't know and it won't concern you if you don't run FS9.
Just keep in mind that some file libraries don't even list FSX soundsets, instead you'll find them in the FS9 category.
Look for Christoffer Petersen, Mike Maarse and Devyn Silverstein -- they're my favorites. 😀
