Abstract

Se puede lograr una versión con reducción de escala de un procedimiento de decodificación de audio con mayor eficacia y/o con un mantenimiento de cumplimiento mejorado si la ventana de síntesis que se utiliza para la decodificación de audio con reducción de escala es una versión submuestreada de una ventana de síntesis de referencia que está implicada en el procedimiento de decodificación de audio sin reducción de escala por medio del submuestreo por el factor de submuestreo por medio del cual la tasa de muestreo submuestreada y la tasa de muestreo original se desvían, y se submuestrea por el uso de una interpolación segmentaria en segmentos de un cuarto de la longitud de la trama.
