Abstract

Un decodificador de señal de audio para proveer una representación de señal de mezcla ascendente sobre la base de una representación de señal de mezcla descendente y una información paramétrica relacionada con el objeto y en dependencia de una información de interpretación comprende un determinador de parámetros de objeto. El determinador de parámetros de objeto está configurado para obtener valores de correlación-inter-objeto para una pluralidad de pares de objetos de audio. El determinador de parámetros de objeto está configurado para evaluar un parámetro de señalización de cadena de bits para decidir si evaluar valores de parámetro de cadena de bits de correlación-inter-objeto individuales para obtener valores de correlación-ínter-objeto para una pluralidad de pares de objetos de audio relacionados, u obtener valores de correlación-inter-obje to para una pluralidad de pares de objetos de audio relacionados usando un valor de parámetro de cadena de bits de correlación-inter-objeto común. El decodificador de señal de audio también comprende un procesador de señal configurado para obtener la representación de señal de mezcla ascendente sobre la base de la representación de señal de mezcla descendente y usar los valores de correlación-inter-objeto para una pluralidad de pares de objetos relacionados y la información de interpretación.
