21.6. azimuth Property

The azimuth property is used to describe the location of a sound in a flat circle surrounding the Web page “viewer” (or, more properly, “listener”). It, along with the elevation property, is designed to allow the Web author to “place” where speech and sound will appear in a three-dimensional sound space. In simpler terms, the azimuth property sets where the sound is placed “around” the listener, and the elevation property sets where the sound is in terms of its “height” above or below the listener.

The azimuth property can take both a numeric value and several preset named values. The numeric value is set in degrees (deg) with a range in angle values from 0 to 360. In this scheme, a value of 0deg places a sound directly in front of the listener, 180deg places it behind the listener, 90deg is to the right, and 270deg is to the left. These numeric values can also be expressed in negatives, so that 90deg is equivalent to -270deg, 180deg is the same as -180deg, 270deg is the same as -90deg, and -0deg is the same as -360deg.
