ABSTRACT
Modern stereophonic recording, or stereo as we normally call it, makes use of many diverse microphone arrays and techniques. At the basis of them all are a set of fundamental two-or three-microphone arrays for picking up a stereo sound stage for reproduction over a pair of loudspeakers. In stereo reproduction the listener is able to perceive images on the stereo sound stage which may span the entire angular width of the loudspeaker array. The sound sources that are perceived between the loudspeakers are known as “phantom images,” because they appear at positions where there are no physical, or real sources of sound.
