real "stereo" sounds would be nice and add alot more, but if you use stereo sounds, AH can't use stereo wavs for placement of external sounds..ie other plane sounds, gvs and i believe gun fire.
So unfortunaly for now, we're stuck with mono sounds for engines, ect...until of if they ever have seperate files for external /ambient sounds.
But Ah does a nice job on the direction of sounds as well as the amount the of volume would change depending on how far the sound source is away from you.
Also the psudeo doppler effect is pretty cool..can really hear it with the different plane engines.....
V2.0 out shortly
