Abstract
Un codificador para proveer una transmisión de audio sobre la base de una representación en el dominio de la transformación de una señal de audio de entrada comprende un calculador de error de cuantificación configurado para determinar un error de cuantificación de múltiples bandas sobre una pluralidad de bandas de frecuencia de la señal de audio de entrada, para la cual está disponible una información separada de ganancia de banda. El codificador también comprende un proveedor de transmisión de audio configurado para proveer la transmisión de audio de modo que la transmisión de audio comprenda una información que describe un contenido de audio de las bandas de frecuencia y una información que describe el error de cuantificación de múltiples bandas. Un decodificador para proveer una representación decodificada de una señal de audio sobre la base de una transmisión de audio codificada, que representa los componentes espectrales de las bandas de frecuencia de la señal de audio, comprende un rellenador de ruido configurado para introducir ruido dentro de los componentes espectrales de una pluralidad de bandas de frecuencia, a las cuales se asocia una información de ganancia de bandas de frecuencia separada sobre la base de un valor de intensidad de ruido de múltiples bandas.An encoder for providing audio transmission on the basis of a representation in the transformation domain of an input audio signal comprises a quantization error calculator configured to determine a multi-band quantization error on a plurality of bands of frequency of the input audio signal, for which a separate bandwidth information is available. The encoder also comprises an audio transmission provider configured to provide the audio transmission so that the audio transmission comprises information describing an audio content of the frequency bands and information describing the multi-band quantization error. . A decoder for providing a decoded representation of an audio signal on the basis of an encoded audio transmission, which represents the spectral components of the frequency bands of the audio signal, comprises a noise filler configured to introduce noise into the spectral components of a plurality of frequency bands, to which a separate frequency band gain information is associated based on a multi-band noise intensity value.
