I uploaded a rough video-mix including a number of tests using Blender Game Engine and OpenAL, alongside other related bge work.
The way it is documented is not terribly detailed but I hope to be helpful enough for someone looking at audio stuff for the BGE. Please bear in mind that this work is made by sound people… (you may forgive my 3D skills!)
