40's In 1940, Walt Disney's Fantasia was the first film to be released in a multichannel format called Fantasound. Conductor Leopold Stokowski and Walt Disney collaborated on the production and concept of this innovative movie.
Fantasia is a feature-length film that choreographs animation to music.
Stotowski wasted to bring mutichannel sound in Fantasia. Bell's most famous demonstration came when the Philadelphia Orchestra, conducted by Stokowski, was transmitted over three telephone lines to an astonished audience in Washington's Constitutional Hall. Eight optical recorders were employed to record the Philadelphia Orchestra conducted by Stokowski. Using multiple optical recorders allowed sections of the orchestra to be handled separately during mixdown, a new concept at the time. Six channels were devoted to individual orchestral sections, one to a distant mic, and another to a balanced mix.
