In a nutshell what I'm essentially aiming for is attenuation in an ellipse rather than spherically.
I'm using Wwise and working on a top-down game with a fixed-angle camera focused on the player. Because the attenuation area is circular I can set it up so that the panning and attenuation on-screen is perfect horizontally but then vertically things aren't quite right - an audio emitter can be a fair way off the top or bottom of the screen but you can still hear it. Is there a way of fudging the attenuation in Wwise to be more of an ellipse to better match what you hear with what you can visibly see on-screen?
