ABSTRACT
Supervising sound editors know they must work quickly and be extremely flexible in custom recording and gathering precise sound cues from the sound effects library to mount their film or audio project. For sound effects, most of people started custom recording our sound effects on 1/4 tape in the 1970s and early 1980s. The equipment was so bulky it had to be mounted inside a vehicle called the sound truck to move it quickly from one location to another. The editor has flipped up the magnetic sound head out of position to check the optical soundtrack from a section of release print. An exciter lamp inside shines a narrow beam of light through the optical track. Light passes through the optical soundtrack image of the film and strikes a photoelectric cell, causing current fluctuations that accurately reproduce the analog audio signal for playback.
