Perspecta

Perspecta was a directional motion picture sound system, invented by the laboratories at Fine Sound Inc. in 1954. As opposed to magnetic stereophonic soundtracks available at the time, its benefits were that it did not require a new sound head for the projector and thus was a cheaper alternative.
