A method and apparatus for stereophonic reproduction uses conventional left and right stereophonic signals to energize a point source transducer in a complementary manner. The resultant interference sound pattern is interpreted by the brain of a listener to enable the listener to experience stereophonic hearing in a wide region surrounding the transducer, not just in the region of the plane of symmetry. A point source transducer may be simulated by a plurality of transducers positioned with the spacing therebetween less than a determinable maximum distance. While conventional stereophonic signals may be employed in the reproduction of sound, improved reproduction is obtained by producing the signals by recording sound with a pair of microphones arranged with the apogees of their respective field of polar response patterns facing substantially at 180° to one another.

Procédé et appareil de reproduction stéréophonique utilisant les signaux stéréophoniques usuels gauche/droite pour activer un transducteur source ponctuel à effet complémentaire. Le schéma d'interférences sonores résultant interprété par le cerveau de l'auditeur lui fournit une audition stéréophonique non seulement dans le plan de symétrie, mais dans un vaste espace entourant le transducteur. Un transducteur source ponctuel peut être simulé par plusieurs transducteurs séparés par des intervalles ne dépassant pas une longueur calculable. Bien qu'il soit possible d'utiliser des signaux stéréophoniques usuels pour la reproduction sonore, on obtient un résultat encore meilleur en se servant pour la production des signaux d'une paire de microphones disposés aux apogées des champs respectifs de leur schéma polaire de réponse et se faisant face sensiblement à 180°.
