Abstract: A general description of the types of movietone sound-track currently being released or to be released in the immediate future, according to plans: (1) single variable-density; (2) single variable-density squeeze; (3) single variable-density double-squeeze; (4) push-pull variable density; (5) push-pull variable-density squeeze; (6) bilateral variable width; (7) duplex variable-width; (8) unilateral variable-width; (9) push-pull variable-width. During the past year all these tracks have been used to some extent in released movietone pictures. Samples of the tracks are shown and described. A description is also included of the general technic involved in recording and reproducing the so-called “Hi-Range” and “Lo-Range” prints. During the past two years this particular type has been used successfully in extending the volume range of variable-density releases to approximately 50 db. This release is intended to be shown only in theaters having equipment adequate to reproduce music 6 to 10 db. higher than average dialog. A description of the mechanics and technic for re-recording with the squeeze-track is outlined. This procedure increases noise-reduction from 3 to 6 db., depending upon the amount of squeeze.
