- Abstract
- One of the essential requirements of a high-fidelity talking motion picture performance is a satisfactory reproducer. The most important limitation to such reproduction at this time, and one that is seriously handicapping those who desire to provide better recordings, is the general lack of sufficiently constant film speed in reproduction. This prevents full use of the advances made in recording machines and technic. In certain kinds of subject material, the performance is ruined for a critical audience by this limitation. For various reasons, little has been published on this problem. This paper describes the technical details of the Photophone high-fidelity reproducer. Measurements of its mechanical constants, together with an elementary analysis of the underlying theory of operation are given.
