Abstract
Decodificador de audio para decodificar una señal de audio codificada que comprende datos de audio multicanal que comprenden datos para dos o más canales de audio e información sobre parámetros de escala codificados conjuntamente, que comprende: un decodificador de parámetros de escala (220) para decodificar la información sobre los parámetros de escala codificados conjuntamente para obtener un primer conjunto de parámetros de escala para un primer canal de una señal de audio decodificada y un segundo conjunto de parámetros de escala para un segundo canal de la señal de audio decodificada; y un procesador de señales (210) para aplicar el primer conjunto de parámetros de escala a una primera representación de canal derivada de los datos de audio multicanal y para aplicar el segundo conjunto de parámetros de escala a una segunda representación de canal derivada de los datos de audio multicanal para obtener el primer canal y el segundo canal de la señal de audio decodificada, en donde los parámetros de escala codificados conjuntamente comprenden información sobre un primer grupo de parámetros de escala codificados conjuntamente e información sobre un segundo grupo de parámetros de escala codificados conjuntamente, y en donde el decodificador de parámetros de escala (220) se configura para combinar un parámetro de escala codificado conjuntamente del primer grupo y un parámetro de escala codificado conjuntamente del segundo grupo usando una primera regla de combinación para obtener un parámetro de escala del primer conjunto de parámetros de escala, y usando una segunda regla de combinación que es diferente de la primera regla de combinación para obtener un parámetro de escala del segundo conjunto de parámetros de escala.
