Conference Paper

On the Naturalness of Two-Channel Stereo Sound

Authors: Theile, Günther

AES Conference: 9th International Conference: Television Sound Today and Tomorrow · Paper 9-024 · February 1991

Abstract

Psychoacoustic principles are considered in order to enhance the naturalness of the sound image achievable in a conventional two loudspeaker arrangement. It is found that simulation of depth and space are lacking when the coincidence microphone and panpot techniques are applied. To obtain optimum simulation of spatial perspective, it is important for the two loudspeaker signals to have inter-aural correlation which is as natural as possible. This requirement is met by the so-called -sphere- microphone, used as a main microphone, associated with the -room-related- balancing technique, which generates artificial reflections and reverberation from spot microphone signals. Music recordings confirm that the sphere microphone combines favorable imaging characteristics with regard to spatial perspective, accuracy of localization, and sound color; and that the room- related balancing technique is able to preserve this stereophonic quality.
