Abstract

La asignación de una de un conjunto de fases de diferentes herramientas de ocultamiento de pérdida de un decodificador de audio a una porción de la señal de audio que se va a decodificar a partir de un flujo de datos, donde la porción se ve afectada por una pérdida, que es la selección del conjunto de diferentes herramientas de ocultamiento de pérdida, puede realizarse de una manera que permita un ocultamiento de pérdida más agradable si la asignación oselección se realiza en función de dos medidas: una primera medida que se determina que mide una posición espectral de un centroide espectral de un espectro de la señal de audio, y una segunda medida que se determina que mide la previsibilidad temporal de la señal de audio. La herramienta de ocultamiento de pérdida asignada o seleccionada puede utilizarse entonces para recuperar la porción de la señal de audio.
