Wave Form Analysis of Variable Density Sound Recording
The harmonic content of variable density sound records, made under a wide variety of conditions, has been investigated by means of a microdensitometer and harmonic analyzer. From these results the conditions of exposure and development giving minimum harmonic content were deduced. These results have been correlated with results obtained by means of photographic tone reproduction diagrams. It has thus been possible to determine the effective emulsion characteristic under various conditions and to determine what changes in the characteristic curve are necessary to bring about further improvement in tone quality and wider latitude in recording and processing conditions.
