How is the coordinate system for Sound.SetPosition set up?

x is obviously left->right
but what about y and z?
is the coordinate system right-handed? is y the back->front (or front->back) axis? etc.

Here is what you have to know about the audio coordinate system :
- it is right handed
- the up axis is always (0, 1, 0)
- the right and front axis are deduced from the target and listener positions

ah, ok, so because the listener is at (0,0,0)' by default, and the default listener target is (0,0,-1)':

(-1,0,0)' is to the left of the listener
(1,0,0)' is to the right of the listener
(0,0,1)' is in front of the listener
(0,0,-1)' is behind the listener

correct?

Yep, should be correct.
