Abstract
Un decodificador para generar una señal de audio mejorada en frecuencia (120), comprende: un extractor de características (104) para extraer una característica de una señal de núcleo (100); un extractor de información lateral (110) para extraer una información secundaria de selección asociada con la señal de núcleo; un generador de parámetros (108) para generar una representación paramétrica para estimar un alcance espectral de la señal de audio mejorada en frecuencia (120) no definida por la señal de núcleo (100), donde el generador de parámetros (108) está configurado para proporcionar un número de alternativas de representación paramétrica (702, 704, 706, 708) en respuesta a la característica (112), y donde el generador de parámetros (108) está configurado para seleccionar una de las alternativas de representación paramétrica como la representación paramétrica en respuesta a la información secundaria de selección (712 a 718) y un estimador de señales (118) para estimar la señal de audio mejorada en frecuencia (120) utilizando la representación paramétrica seleccionada.
