Abstract
Se describen métodos de procesamiento de una señal de audio para la ocultación de pérdida de paquetes. La señal de audio comprende una secuencia de tramas, cada trama que contiene representaciones de una pluralidad de canales de audio y parámetros de reconstrucción para la premezcla multipista de la pluralidad de canales de audio a un formato de canal predeterminado. Un método incluye: recibir la señal de audio; y generar una señal de audio reconstruida en el formato de canal predefinido con base en la señal de audio recibida. La generación de la señal de audio reconstruida comprende: determinar si al menos una trama de la señal de audio se ha perdido; y si un número de tramas perdidas consecutivamente excede un primer umbral, desvanecer la señal de audio reconstruida a una configuración espacial predefinida. Se describe además un método de codificación de una señal de audio. Aún se describen adicionalmente aparatos para llevar a cabo los métodos, así como programas correspondientes y medios de almacenamiento leíbles por computadora.
