Abstract
Un dispositivo procesador de señales de audio comprende un detector de discontinuidad configurado para determinar una incidencia de una discontinuidad a partir de un incremento repentino de una amplitud de audio decodificado obtenido al decodificar el primer paquete de audio que se recibe correctamente después de una incidencia de una pérdida de paquetes, y un corrector de discontinuidad para corregir la discontinuidad de audio decodificado.
