Abstract
Se proporciona un aparato para generar una señal de salida de audio basada en un espectro codificado de la señal de audio. El aparato comprende una unidad de procesamiento (115) para procesar el espectro codificado de la señal de audio para obtener un espectro descodificado de la señal de audio que comprende una pluralidad de coeficientes espectrales, donde cada uno de los coeficientes espectrales tiene una ubicación espectral dentro del espectro codificado de la señal de audio y un valor espectral, donde los coeficientes espectrales están ordenados secuencialmente de acuerdo con sus ubicaciones espectrales dentro del espectro codificado de la señal de audio de manera tal que los coeficientes espectrales forman una secuencia de coeficientes espectrales. Asimismo, el aparato comprende un determinador de pseudo-coeficientes (125) para determinar uno o más pseudo-coeficientes del espectro descodificado de la señal de audio, cada uno de los pseudo-coeficientes tiene un valor espectral. Además, el aparato comprende una unidad de reemplazo (135) para reemplazar al menos uno o más pseudo-coeficientes por un patrón espectral determinado para obtener un espectro modificado de la señal de audio, donde el patrón espectral determinado comprende al menos dos coeficientes de patrón, donde cada uno de al menos dos coeficientes de patrón tiene un valor espectral. Asimismo, el aparato comprende una unidad de conversión de espectro-tiempo (145) para convertir el espectro modificado de la señal de audio al dominio de tiempo para obtener la señal de salida de audio.
