Variable-Area Release from Variable-Density Original Sound Tracks

The variable-density and variable-area systems of recording sound on film, with the many available forms of standard or push-pull tracks, enable the sound engineer to select the type of sound track best suited to his particular problems. — A combination of 200-mil variable-density push-pull tracks for original recording and 100-mil variable-area standard tracks for theater release has been successfully employed by the Sound Department of Columbia Studios on a number of productions. This combination has been found to provide high output in the theater with low overall distortion values. — The processing of standard variable-area tracks in different release laboratories has long been a critical problem. A method is described which greatly simplifies the solution of this problem and which, in its application, has proved to be thoroughly practical under widely varying conditions.
