Abstract
A system including a compact array of special purpose microphones and an encoder, especially suited for use with surround-sound sources, for producing two composite output signals equivalent to those required by the 'SQ' quadraphonic system to establish the directional position of the sources. The output signals from the system can be used directly to record an 'SQ'-matrixed tape, or they can be applied to a disc cutter to produce an 'SQ' record, or they can be broadcast for reception by FM receivers equipped with an 'SQ' decoder, resulting in the generation of outputs in the quadraphonic 'SQ' listening system which reproduce the directional characteristic of the original sound sources. Thus, the system performs the function of a conventional multimicrophone and encoder system for 'SQ' recording or broadcasting.
