Sound
Although few cameras were made that could record the sound directly onto the film (Fairchild Cinephonic Eight cameras, Fairchild Professional 900 cameras, and Pictorial cameras), there were many projectors that could record and replay sound on a magnetic stripe. For cameras, this stripe had to be added to the film before it had been exposed. For projectors, the stripe had to be added to the film after it had been processed. The stripe was added between the perforations and the edge of the film (see illustration at head of article). Sometimes a balance stripe was added on the opposite edge. This had no purpose other than to allow the film to be completely flat in front the projection window. For synchronised sound, the sound was specified as 56 frames in advance of the picture On the Cinephonic Eight cameras, the picture/sound separation was 52 frames. Fifty six frames was the same physical distance as magnetic sound was specified for the 16mm film format (or 28 frames in that format). Optical sound for 8mm format had been used only on commercial films and some projectors. Fujica made a camera with optical sound recording (Fuji ZS400 cameras), but it was in Single 8 format.

Famous quotes containing the word sound:
“It is not only their own need to mother that takes some women by surprise; there is also the shock of discovering the complexity of alternative child-care arrangements that have been made to sound so simple. Those for whom the intended solution is equal parenting have found that some parents are more equal than others.”
—Elaine Heffner (20th century)
“Philosophy ... does not talk, but write, or, when it comes personally before an audience, lecture or read; and therefore it must be read to-morrow, or a thousand years hence. But the talker must naturally be attended to at once; he does not talk on without an audience; the winds do not long bear the sound of his voice.”
—Henry David Thoreau (1817–1862)
“If man is reduced to being nothing but a character in history, he has no other choice but to subside into the sound and fury of a completely irrational history or to endow history with the form of human reason.”
—Albert Camus (1913–1960)
