How long before 3d soundtracks?
By 3d, I mean companies keep adding all these channels around the listener in the left/right/front/back directions, but not in the up and down directions.
eg. If a plane flies over from behind you, the sound doesn't, it just goes straight through you from front to back. How long will it be before we have a sense of up and down in the soundtrack as well? Or has it already been done?
