Abstract
Un codificador de audio para proveer una información de audio codificada sobre la base de una información de audio de entrada comprende un codificador de baja frecuencia configurado para codificar una porción de baja frecuencia de la información de audio de entrada a efectos de obtener una representación codificada de la porción de baja frecuencia, y un proveedor de información de ampliación de ancho de banda configurado para proveer información de ampliación de ancho de banda sobre la base de la información de audio de entrada. El codificador de audio está configurado para incluir selectivamente información de ampliación de ancho de banda en la información de audio codificada de una manera que se adapta a las señales. Un decodificador de audio comprende un decodificador de baja frecuencia configurado para decodificar una representación codificada de una porción de baja frecuencia a efectos de obtener una representación decodificada de la porción de baja frecuencia, y un ampliación de ancho de banda configurada para obtener una señal de ampliación de ancho de banda utilizando una ampliación de ancho de banda a ciegas para porciones de un contenido de audio para las que no hay parámetros de ampliación de ancho de banda incluidos en la información de audio codificada, y para obtener la señal de ampliación de ancho de banda utilizando un ampliación de ancho de banda guiada por parámetros para porciones del contenido de audio para las que hay parámetros de ampliación de ancho de banda incluidos en la información de audio codificada.
