3D sound ... (inverse volume levels) ???

I have implimented a sound region that (when entered) emits a background music.

I have set the 3d parameter and it works great ... BUT (why is there always a 'but' ?) ... something very strange happening with the volume... its almost like it's in reverse. I have set the maxfdist & minfdist parameters ... and they work great ... when I walk away from the sound it gets quieter...perfect!

Now, this is where it gets weird...

It's most noticable as you get closer to the 'edge' of the maxfdist area ... whilst it does get quieter as i go further away from the sound emiter, if I FACE the sound emiter it's QUITER than if I stand on the spot and spin around and face AWAY from the emiter, (when it gets LOUDER).

The correct channel is playing the sound (left and right) ... its the volume thats wrong. Surely, if you face an emiter the sound should be louder than it is when having your back to it?

(I know nothing about the plugin and how it handles sound, but it seems like the volume setting is in reverse - louder facing away from a sound and quieter when you face the sound)

Has anyone else noticed it?

(I have been playing with (sorry, testing) this for about 2 hours ... changing the y axis direction in local, changing the left, right channel parameters in Alcscript, all kinds of settings ... but, whatever I do, I can't make it work correctly)

Are you using third person view? Sound is always played from the camera's perspective, so when you turn around, it moves behind you, which is farther away from the sound...

If you're using first person, then it should become muffled when facing away from it, but not necessarily quieter.

I always test most of my stuff in 1st person view, and for me, the sound gets muffled a little when I turn away from the emitter if I'm using 3d sound.
I have not tried it in 3rd person though.

DOH ... (as usual) ... I must admit I never noticed that before, (but now I've got that perception in my head) it works correctly. In first person there is no change in volume (obviously becuase the camera doesn't move). Thanks for clearing that up, I was begining to think I was going mad ! (well, now that I mention it ... blahh..blahh...blah :roll: )
