Abstract

Se describe un método, un sistema, y un producto programa de computador para procesar una señal de audio codificada. En una implementación ejemplar el sistema recibe una señal codificada del rango de frecuencia baja e información de energía codificada utilizada para desplazar la frecuencia de la señal codificada del rango de frecuencia baja. La señal de rango de frecuencia baja se decodifica y se suaviza la depresión de energía de la señal decodificada. La señal suavizada del rango de frecuencia baja es frecuencia desplazada para generar una señal delrango de frecuencia alta. Luego, la señal del rango de frecuencia baja y la señal del rango de frecuencia alta se combinan y se sacan.
