Abstract

Un codificador para codificar una señal de audio. El codificador está configurado para codificar la señal de audio en el dominio de la transformada o en el dominio de banco de filtros, donde el codificador está configurado para determinar coeficientes espectrales de la señal de audio correspondientes a una trama actual y por lo menos una trama anterior, donde el codificador está configurado para aplicar selectivamente la codificación predictiva a una pluralidad de coeficientes espectrales individuales o grupos de coeficientes espectrales que están separados por al menos un coeficiente espectral.
