Abstract

Système de reproduction sonore permettant à un auditeur de distinguer les sons provenant de tout point de l'espace. Le décodeur comporte des paires distinstes de bornes de sortie reliées à des haut-parleurs en nombre plus grand que le nombre des amplificateurs de puissance. Les bornes de sortie sont reliées soit à des bornes de sortie d'autres paires, soit à des bornes de sortie de puissance des amplificateurs pour des connexions à impédance nulle. Les tensions produites aux bornes de chaque groupe de trois paires de bornes de sortie de décodage sont linéairement indépendantes l'une de l'autre. Application à la reproduction sonore spatiale.
