パースペクタ・ステレオ
1. PerspectaPerspecta 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. Introduced as a "directional sound system" rather than a true stereophonic sound system, Perspecta did not utilize discretely recorded sound signals.
