RADICAL NEW SOUND DEVELOPMENT— Suggests New Technique The first public showing of Walt Disney's "" un- veiled an entirely new type of motion picture sound recording and reproduction which projects a complete third-dimensional effect of sound and music. Christened "Fantasound" because, like the picture itself, it represents a revolutionary technique in sound reproduction. The new system of recording and re- producing sound-on-film employs entirely new principles both in the studio production and in theatre presentation. Three years of work by Disney and RCA engineers went into its de- velopment. "Fantasound" causes sound actually to move with the action on the screen. This realism in sound is accomplished by the use of a number of loudspeakers placed at different points behind the motion picture screen. It succeeds in taking music and sound out of its incidental role in the theatre and elevating it to the position of an important tool in the hands of the dra- matist. The result can best be described as surprisingly de- lightful, or to quote Disney, it is "seeing music and hearing pictures". Screen sounds come forth with flexibility for the first time. The music can be followed with the eyes as well as with the ears not only all over the screen but also around the theatre.
