Abstract: The recent improvements in sound quality resulting from the extension of the frequency and intensity ranges are the results of coordinated activity in recording equipment and processes, reproducing equipment, and theater acoustics. This paper discusses the recording phase of the process. A wide-range recording channel consists essentially of the moving-coil microphone, suitable amplifiers, a new recording lens, and certain electrical networks. The characteristics of such a system, from the microphone to and including the processed film, are shown. Other factors fundamentally associated with wide-range recording, such as monitoring, film processing, the selection of takes in the review room, and re-recording, are also discussed. The changes brought about by this system of recording result, first, in a greater freedom of expression and action on the part of the actor; and, second, a much greater degree of naturalness and fidelity than has been previously achieved.
