Abstract

Los ejemplos de modalidades proporcionan métodos de codificación y decodificación, y codificadores y decodificadores asociados, para codificar y decodificar una escena de audio que comprende al menos uno o más objetos de audio (106a). El codificador (108, 110) genera una secuencia de bits (116) que comprende señales de mezcla (112) e información lateral que incluye elementos individuales de matriz (114) de una matriz de reconstrucción que facilitan la reconstrucción del uno o más objetos de audio (106a) en el decodificador (120).
