Pick-up for Sound Motion Pictures (Including Stereophonic)
Joseph P. Maxfield, A. W. Colledge, R. T. Friebus · Journal of the Society of Motion Picture Engineers · 1938
Although the basic principles underlying sound pick-up for motion pictures have been understood for some time, the ability to carry them out completely in the presence of the requirements of artistry, photography, lighting, etc., has constituted a difficult problem. The paper discusses some of these problems, particularly with respect to the acoustics of production sets and scoring stages. The problems of stereophonic reproduction are also discussed in some detail.
