Abstract

L'invention concerne un appareil et un procédé de traitement d'un signal audio. L'invention concerne la réception d'un signal audio et d'informations prédéfinies; l'obtention d'une matrice prédéfinie à partir d'informations prédéfinies, la matrice prédéfinie indiquant que le degré de contribution de l'objet vers le canal de sortie; et le réglage du niveau de sortie de l'objet au moyen de la matrice prédéfinie. De ce fait, sans les paramètres de l'utilisateur pour chaque objet, lorsque les métadonnées prédéfinies à appliquer à un signal audio sont sélectionées en référence à des métadonnées prédéfinies précédemment, les niveaux d'objets compris dans le signal audio peuvent être réglés au moyen des données de rendu prédéfinies correspondant aux métadonnées prédéfinies sélectionnées.
