Abstract
Un aparato para decodificar una señal de audio, comprende un decodificador de audio del dominio espectral (112) para generar una primera representación codificada de un primer conjunto de primeras porciones espectrales, la representación decodificada que tiene una primera resolución espectral; un decodificador paramétrico (114) para generar una segunda representación decodificada de un segundo conjunto de segundas porciones espectrales que tienen una segunda resolución espectral que es más baja que la primera resolución espectral; un regenerador de frecuencia (116) para regenerar toda segunda porción espectral construida que tiene la primera resolución espectral usando una primera porción espectral e información de envolvente espectral para la segunda porción espectral; y un convertidor espectro-tiempo (118) para convertir la primera representación decodificada y la segunda porción espectral reconstruida en una representación del tiempo.An apparatus for decoding an audio signal, comprises an audio decoder of the spectral domain (112) to generate a first encoded representation of a first set of first spectral portions, the decoded representation having a first spectral resolution; a parametric decoder (114) for generating a second decoded representation of a second set of second spectral portions having a second spectral resolution that is lower than the first spectral resolution; a frequency regenerator (116) for regenerating any second constructed spectral portion having the first spectral resolution using a first spectral portion and spectral envelope information for the second spectral portion; and a spectrum-time converter (118) to convert the first decoded representation and the second reconstructed spectral portion into a time representation.
