Perspecta Sound was an attempt at a stereo-like sound process on film which was invented in 1954 and was supported by major studios like Paramount Pictures and Metro-Goldwyn-Mayer.

The Perspecta Sound process was not a true stereophonic sound process but actually took sounds that were recorded at certain tones and levels and distributed them along the left, center, and right speakers through the Perspecta Sound processor, thus creating a pseudo-stereo effect from a mono sound source, which was beneficial for theaters that did not want to install new sound heads on projectors in order to take advantage of the stereophonic sound that was available with FOX’s CinemaScope and other widescreen film processes, making Perspecta Sound a cost effective substitute for stereophonic sound, which the only major cost was the processor inself.

Unfortunately, Perspecta Sound was short lived, and fell out of grace with studios in 1958.
