Experiment in Stereophonic Sound
Lorin D. Grignon · Journal of the Society of Motion Picture Engineers · 1949
This paper reports an extension of the theory and methods of stereophonic recording and reproduction, as particularly applicable to motion pictures. Microphone technique becomes very different from that previously used because of the manner of staging, the use of varied angles of view by the camera, and a fixed theater picture size. Typical microphone technique is illustrated and re-recording with added sound effects is described. Resulting conclusions and observations establish a good foundation for further work in this field.
