Abstract
Se proporciona un método para aproximar una trama de audio multicanal perdida o dañada de una señal de audio multicanal en un dispositivo de decodificación. El dispositivo puede generar una trama de ocultación de errores de mezcla descendente y transformar la trama en un dominio de frecuencia para generar una trama de ocultación de errores de mezcla descendente transformada. El dispositivo puede descorrelacionar la trama transformada para generar una trama de ocultación descorrelacionada. El dispositivo puede obtener un espectro de señal residual de una señal residual almacenada de una trama de señal de audio multicanal previamente recibida y generar una trama de ocultación de señal residual descorrelacionada con energía ajustada usando el espectro de señal residual. El dispositivo puede obtener un conjunto de parámetros de sustitución de audio multicanal y proporcionar las tramas y los parámetros de sustitución a un componente de síntesis de audio para generar una trama de audio multicanal sintetizada. El dispositivo lleva a cabo una transformación de dominio de frecuencia inverso de la trama de audio para generar una trama de sustitución para la trama de audio perdida o dañada.
