Sound-on-film is a class of sound film processes where the sound accompanying a picture is recorded onto photographic film, usually, but not always, the same strip of film carrying the picture. Sound-on-film processes can either record an analog sound track or digital sound track, and may record the signal either optically or r technologies were sound-on-disc, meaning the. Sound recording and reproduction is an electrical, mechanical, electronic, or digital inscription and re-creation of sound waves, such as spoken voice, singing, instrumental music, or sound two main classes of sound recording technology are analog recording and digital recording.. Acoustic analog recording is achieved by a microphone diaphragm that senses changes in atmospheric. In , "A Clockwork Orange" used Dolby A on magnetic sound-on-film with great success. Eastman Kodak worked with RCA and Dolby in the early s to develop stereo variable area (SVA), an optical method that offered stereo sound by using two variable width lines in the space that was originally allocated for one. Magnetic sound film with a film base having perforations along one or both edges bearing a ferro-magnetic coating, either completely across the film or in stripes, the coating capable of accepting and reproducing sound records. Unperforated materials are usually referred to as magnetic soundtrack on 70mm film (Dolby®). Full-coat-between-perforations is film that has the magnetic coating.
The history of sound recording - which has progressed in waves, driven by the invention and commercial introduction of new technologies — can be roughly divided into four main periods. the "Acoustic" era, to ; the "Electrical" era, to ; the "Magnetic" era, to ; the "Digital" era, to the present day.

These systems are thick and seldom used for books, unlike magnetic systems, but they are relatively better at detection (fewer false positives and negatives) than magnetic tags.
Magnetic sound definition is - sound recorded magnetically instead of photographically on a motion-picture film. The following 31 feature films were released in 35mm magnetic stereophonic sound from Septem to October 1, THE ROBE was four channel stereophonic and shown on a single-strip composite picture/track 35mm print using the new Simplex X-L magnetic reproducer. Super 8mm film is a motion picture film format released in by Eastman Kodak as an improvement over the older "Double" or "Regular" 8 mm home movie format.. The film is nominally 8mm wide, the same as older formatted 8mm film, but the dimensions of the rectangular perforations along one edge are smaller, which allows for a greater exposed area. The Super 8 standard also allocates the. Sound Book Production.
