What is 3D Audio ?
3D Audio is a generic name that encompasses ways to render audio like in reality and in particular its spatial dimension; it is the capability to produce and perceive sounds in any direction and at any distance. At 3D Sound Labs we prefer to call this technology Virtual Reality Audio or VR Audio.
3D Audio can be reproduced over many loudspeakers positioned all around the listener. A good example of this application is the Dolby Atmos system designed for Movie Theaters. For headphones, the technology used is called Binaural Synthesis. It consists of simulating, at someone’s eardrums, the same acoustical sound field produced as the one which would have been produced by a real audio scene.
Binaural synthesis, which is therefore the capability to produce 3D Audio over headphones is fast becoming a key technology brick needed by content producers and device/application developers active in the fields of Virtual and Augmented Reality
