Abstract

Un método, decodificador y código de programa para llenar una longitud del periodo de análisis con una señal del dominio de tiempo para ocultar una trama de audio perdida asociada con una señal de audio recibida. Un primer segmento de una parte recibida previamente de una señal de audio recibida se copia a partir de un búfer de prototipo. Un segundo segmento de la parte recibida previamente de la señal de audio recibida está superpuesta añadida a partir del búfer de prototipo a una porción inicial de una parte reconstruida de la señal de audio recibida seguido de una porción restante de la parte reconstruida de la señal de audio recibida.
