Headphones Required! This video demonstrates binaural audio (3D Audio) along with video. The recording was done using a dummy head with silicone binaural ears, thus creating a completely 3D audio experience. See http://BinauralEars.com
Recording 3D audio is easy to do, and amazingly effective at capturing the natural environment. Binaural 3D audio can allow you to relive any situation, with even more realism than with video. All you need to listen back are headphones.
