Production and Release Applications of Fine-Grain Films for Variable-Density Sound Recording

C. R. Daily, I. M. Chambers

Fine-grain film materials have supplanted the normal positive type emulsions for all variable-density sound-recording and printing operations. The sound-quality improvement realized by the reduction in noise and distortion is now available for all sound operations, including release prints. The paper describes a number of problems encountered and solved in the commercial application of such films for sound recording, including factors affecting the choice of negative and print materials, noise, distortion, sensitometric characteristics, recorder lamp supplies, and noise problems on stages.
