Abstract

Une unité de conversion M/S (110) convertit un signal acoustique stéréo AS1 en un signal de somme MS1 et un signal de différence SS1. Une unité de fourniture d'effets (120M) confère un effet acoustique au signal de somme MS1, et une unité de fourniture d'effets (120S) confère un effet acoustique au signal de différence SS1. Une unité de reconversion M/S (150) convertit un signal de somme MS2 et un signal de différence SS2 auxquels sont conférés les effets acoustiques dans un signal acoustique stéréo AS2. Une première unité de commande (160) commande les propriétés respectives des effets acoustiques des unités de fourniture d'effets (120M, 120S) d'après la valeur d'un premier paramètre de fonctionnement OP1. Une seconde unité de commande (170) commande les degrés respectifs des effets acoustiques des unités de fourniture d'effets (120S) d'après la valeur d'un second paramètre de fonctionnement OP2.
