Abstract

Le dispositif décrit comporte un codeur et un décodeur dont les structures de circuit permettent le codage par bande des signaux de radiodiffusion sonore dans une zone spectrale compte tenu de l'effet de masquage à l'intérieur des bandes critiques de la voix humaine, ainsi que la réduction de la vitesse du flux de données dans un canal individuel de radiodiffusion sonore tout en maintenant la qualité élevée de sa reproduction au cours du décodage.
