In combination with elevation, the azimuth CSS property enables different audio sources to be positioned spatially for aural presentation. This is important in that it provides a natural way to tell several voices apart, as each can be positioned to originate at a different location on the sound stage. Stereo output produce a lateral sound stage, while binaural headphones and multi-speaker setups allow for a fully three-dimensional stage.

Audible source position is described as an angle within the range -360deg to 360deg. The value 0deg means directly ahead in the center of the sound stage (this is the default value). 90deg is to the right, 180deg is behind, and 270deg or -90deg is to the left.

[1] Although the aural media group was recognized in Gecko prior to Gecko 6.0 (Firefox 6.0 / Thunderbird 6.0 / SeaMonkey 2.3), it was not implemented. What little code there was to attempt to process it was removed in Gecko 6.0.
