Abstract
Un códec y a un clasificador de señales y a los métodos para la clasificación de señales y la selección de un modo de codificación en base a características de la señal de audio. Un método de forma de realización a ser llevado a cabo por un decodificador comprende, para una trama m: determinar un valor de estabilidad D(m) en base a una diferencia, en un dominio de la transformada, entre un rango de una envolvente espectral de la trama m y un rango correspondiente de una envolvente espectral de una trama adyacente m - 1. Cada rango comprende un conjunto de valores de envolvente espectrales cuantificadas relacionados con la energía en las bandas espectrales de un segmento de la señal de audio. El método comprende más aun seleccionar un modo de decodificación, de una pluralidad de modos de decodificación, en base al valor de estabilidad D(m); y aplicar el modo de decodificación seleccionado.
