Abstract

Un aparato para codificar una señal de audio, que comprende: un codificador de núcleo para codificar el núcleo de una primera información de audio en una primera banda espectral; un codificador paramétrico para codificar paramétricamente una segunda información de audio en una segunda banda espectral que es diferente de la primera banda espectral, donde el codificador paramétrico comprende: un analizador para analizar una primera información de audio en la primera banda espectral para obtener un primer resultado de análisis y para analizar una segunda información de audio en la segunda banda espectral para obtener un segundo resultado de análisis; un compensador para calcular un valor de compensación usando el primer resultado de análisis y el segundo resultado de análisis; y un calculador de parámetros para calcular un parámetro de una segunda información de audio en la segunda banda espectral usando el valor de compensación.
