Very Early Sound-on-Film Internal Document from RCA+++ RCA Photophone / Sound Reproduction From Film. Engineering Department. Blueprint, 6 leaves, 11x8 inches, plus one original photograph (8 x 4 inches) of the machine, produced ca. 1930-2. This a sound-on-film incunable. This means the pamphlet was printed within the first few years of the first "talking" (synchronized sound, or sound technologically coupled to image) motion picture. The first feature length film using sound throughout (1) the length of the movie was The Jazz Singer, which was released in 1927 and used a sound-on-disc (2)The technology of sound-on-film would take the day, and in very short order, leading to four different systems, of which the Photophone was one. Photophone's share of the prospective studio users was pretty good: the earliest major producers/licensees included Walt Disney Productions (after 1932), RKO Radio Pictures, republic Pictures, Warner Borthers, and Pathe. system of recording. That means that the audio portion of the film was recorded onto records, and then synchronized in playback with the film to match up the audio and video--this technology was obviously not the future.+++Notes: 1. Earlier on in the mid-1920's there were efforts of using sound in film but limited to music or very specific areas of the film, most of which in the end was silent. 2. The movie was made with the Vitaphone system, which was not long for this world, soon to be replaced by the more sophisticated sound-on-film systems. "In 1925 GE started a program to develop commercial sound-on-film equipment based on Hoxie's work. Unlike the Phonofilmand Movietone systems in which the audio modulated the intensity of a recording lamp which exposed the soundtrack, thus creating a variable-density track, the GE system employed a fast-acting mirror galvanometer to create a variable-area soundtrack. A number of demonstrations of this system, now known as Photophone, were given in 1926 and 1927. The first public screenings with this system were of a sound version (music plus sound effects only) of the silent film Wings which was exhibited as a road-show in around a dozen specially equipped theatres during 1927."--Wiki.
