Stereophonic sound


 

Stereophonic sound, commonly called stereo, is the reproduction of sound, using two independent audio channels, through a pair of widely separated speaker systems, in such a way as to create a pleasant and natural impression of sound heard from various directions as in natural hearing.

Other uses of the word

Because of this usage, "stereo" or "in stereo" is sometimes used colloquially for when two, as distinct from one, of something are present.
