Given the delay between theatrical and Blu-ray Disc release, 2011 could well be the year that equipping your home theater with a 3D-capable TV and BD player will become compelling enough to bite the 3D bullet. And you might consider upgrading to a 7.1 channel or higher sound system, since being able reproduce more discrete audio channels will put you in the center of the sonic space.
For audio engineers, it’s time to start thinking about applying well-established surround-sound techniques as enhancements to the 3D visuals. Your audience is already accustomed to the sound of a moving vehicle panning across the left, center, and right speakers. They wouldn’t expect anything less in the case of a chopper as it lifts off from the White House lawn whirling from the front to rear speakers. With 3D, the Z axis becomes more prominent as sound moves from deep inside the screen to an infinite position in front or above the screen.
With a little imagination it won’t be difficult to come up with ways to enhance the 3D visuals with 3D sound. To start thinking about uses, here’s a baker’s dozen:
