The optical soundtrack, as printed along the side of the film, is going to have its signal range limits that cannot really be surpassed. Magnetic recording allowed for stereo sound and surround sound, and also improved the sound quality. Magnetic recording The most prevalent current method of recording analogue sound on a film print is by stereo variable-area (SVA) recording, a technique first used in the mid-1970s as Dolby Stereo. These LED or laser exciters are backwards-compatible with older tracks. Optical recording is a method of recording either data, audio content or video content in a form which is played back using light. Briefly described are the technical parameters and the designing peculiarities of the sound‐equipment basic elements, and the main features of the modern technology of sound recording‐reproduction in cinematography. Of this small percentage of film reels that do have a sound line, an even smaller percentage used the proper recording equipment required to capture both the sound and picture. The light being modulated by the recording is turned into electrical sound signals via a phototube or photodiode. This is usually done with a disc as the storage medium. Photographic film stock was exposed to light modulated by the signal to be recorded. they recorded sound separate from picture.. Selling to the studios • De Forest offered his technology to Universal and Paramount who thought sound was a passing fad. Corrections? Sound-on-film processes can either record an analog sound track or digital sound track, and may record the signal either optically or magnetically. When a positive was printed the result was a clear area of varying width.

This could be general ambient sound or the sound of an actor picking up a prop. Almost all sound formats used with motion-picture film have been sound-on-film formats, including: Kreimeier, K. (translation: Hill and Wang). The projector shines light from a small lamp, called an exciter, through a perpendicular slit onto the film. Methods of Optical Recording of Sound on Film • Variable-Density Method: In this method,sound is picked up by microphone,and converted into electrical signals which are amplified.Audio o/p of the amplifier is fed to the anode of special type of vaccum tube,called an AEO lamp.The lamp contains a little quantity of helium gas.The anode gets high dc voltage in series with the audio … In August 1948, Warner Bros. was the first studio to test a 35mm magnetic recorder during production of THE FOUNTAINHEAD. Magnetic tape contains static, humming, and other electromagnetic disruptions whereas optical tape does not. Note: Presents the complications in archiving that have taken place with the advent of digital audio recording technology, most notably incompatibility of systems and/or media. Unlike other cabling standards, the optical audio system uses fiber optic cables and laser light to transmit digital audio signals between devices. In the 1950s optical soundtracks were replaced by magnetic recording -- magnetic strips just like those on a cassette tape were applied to the film and sound was recorded on them (see How Cassette Tape Works for details). Optical film sound tracks represent changes in amplitude by varying the amount of light that passes through the film—varying either the density (as above on the left) or the width (as on the right). Synchronising sound and picture during post-production has been a familiar task for us editors for aeons! This allowed for the sound to be heard while the film was running because the projector has built in heads that can output sound from the magnetic or optical strip. of motion pictures.
