Azimuth

The CSS   property provides a natural way to tell several voices apart, as in real life (people rarely all stand in the same spot in a room). Stereo speakers produce a lateral sound stage. Binaural headphones or the increasingly popular 5-speaker home theater setups can generate full surround sound, and multi-speaker setups can create a true three-dimensional sound stage. VRML 2.0 also includes spatial audio, which implies that in time consumer-priced spatial audio hardware will become more widely available. The ideal listening position is considered to be perfectly facing the main sound reproduction source(s) at an optimal distance. This property describes the radial position (360 degree measure) on this listening plane. An imaginary axis can be drawn straight ahead of the listener with the imaginary line serving as the origin. Rightward angle measures are positive and leftward, negative.
