A Compatible Photographic Stereophonic Sound System
This paper describes a 2-channel photographic stereophonic system, variable-density and variable-area, the two soundtracks occupying the same position as the normal single track on release film. Methods of recording using either a straight 2-microphone or an alternate system with a bridged center microphone are described. Methods of reproducing over a 2-loudspeaker or over a 3-loudspeaker system with the center bridged to the outer two are described. Tracks recorded in this manner may be played over standard theater systems equipped for single soundtrack only. Standard single tracks may be played over this system by means of a simple operating change in the booth.
