Abstract

896,372. Stereophonic systems. ELECTRIC & MUSICAL INDUSTRIES Ltd. Aug. 27, 1958 [June 6, 1957], No. 18009/57. Class 40 (4). In a sterophonic transmission or recording system in which a first channel derives from one or more sources of sound a signal representative of the sounds and a second channel derives a control signal representative of the directional or spatial distribution of the sound sources, the microphones of the respective channels are located at different positions so as to reduce the relative delay between an element of the sound signal and the corresponding element of the control signal, arising from the different signal delays in the two channels, to a value substantially less than it would be were the microphones coincident. Specification 871,992 is referred to.
