Abstract
La presente da a conocer un decodificador de audio que está configurado para decodificar un flujo de bits para producir a partir de éste una señal de salida de audio, donde el flujo de bits comprende por lo menos una fase activa seguida por al menos una fase inactiva, donde el flujo de bits contiene, codificada en el mismo, por lo menos una trama de descriptor de inserción de silencio que describe un espectro de un ruido de fondo, donde el decodificador de audio comprende: un decodificador de descriptores de inserción de silencio configurado para decodificar la trama de descriptor de inserción de silencio a fin de reconstruir un espectro del ruido de fondo; un dispositivo decodificador configurado para reconstruir la señal de salida de audio a partir del flujo de bits durante la fase activa; un conversor espectral configurado para determinar un espectro de la señal de salida de audio un dispositivo estimador de ruido configurado para determinar un primer espectro del ruido de la señal de salida de audio sobre la base del espectro de la señal de salida de audio provista por el conversor espectral, donde el primer espectro del ruido de la señal de salida de audio tiene una resolución espectral más alta que el espectro del ruido de fondo; un conversor de resolución configurado para establecer un segundo espectro del ruido de la señal de salida de audio sobre la base del primer espectro del ruido de la señal de salida de audio, donde el segundo espectro del ruido de la señal de salida de audio tiene la misma resolución espectral que el espectro del ruido de fondo; un dispositivo de estimación del espectro del ruido de confort que consta de un dispositivo de cómputo de factores de escala configurado para calcular factores de escala para un espectro respecto del ruido de confort sobre la base del espectro del ruido de fondo provista por el decodificador de descriptores de inserción de silencio y sobre la base del segundo espectro del ruido de la señal de salida de audio provista por el conversor de resolución y tiene un generador de espectros de ruido de confort configurado para calcular el espectro correspondiente a un ruido de confort sobre la base de los factores de escala y un generador de ruido de confort configurado para producir el ruido de confort durante la fase inactiva sobre la base del espectro correspondiente al ruido de confort.
