Abstract
Un aparato para codificar una señal multicanal que comprende por lo menos dos canales, comprende: un convertidor tiempo-espectral (1000) para convertir secuencias de bloques de valores de muestra de los por lo menos dos canales en una representación en el dominio de las frecuencias que tiene secuencias de bloques de valores espectrales para los por lo menos dos canales, en donde un bloque de valores de muestreo tiene una velocidad de muestreo de entrada asociada, y un bloque de valores espectrales de las secuencias de bloques de valores espectrales tiene valores espectrales hasta una frecuencia de entrada máxima (1211) que está relacionada con la velocidad de muestreo de entrada; un procesador multicanal (1010) para aplicar un procesamiento multicanal conjunto a las secuencias de bloques de valores espectrales o a secuencias remuestreadas de bloques de valores espectrales para obtener por lo menos una secuencia resultado de bloques de valores espectrales que comprende información relacionada con los por lo menos dos canales; un remuestreador en el dominio espectral (1020) para el muestreo repetido de los bloques de las secuencia resultado en el dominio de las frecuencias o para el muestreo repetido de las secuencias de bloques de valores espectrales para los por lo menos dos canales en el dominio de las frecuencias para obtener una secuencia remuestreada de bloques de valores espectrales, en donde un bloque de la secuencia remuestreada de bloques de valores espectrales tiene valores espectrales hasta una frecuencia de salida máxima (1231, 1221) que es diferente de la frecuencia de entrada máxima (1211); un convertidor espectral-tiempo para convertir la secuencia remuestreada de bloques de valores espectrales en una representación en el dominio del tiempo o para convertir la secuencia resultado de bloques de valores espectrales en una representación en el dominio del tiempo que comprende una secuencia de salida de bloques de valores de muestreo asociada con una velocidad de muestreo de salida que es diferente de la velocidad de muestreo de entrada; y un codificador de núcleo (1040) para codificar la secuencia de bloques emitida de valores de muestreo para obtener una señal multicanal codificada (1510).
