Abstract

La invención se refiere a un códec y un discriminador y métodos en el mismo para la discriminación de la señal de audio y la codificación. Las modalidades de un método realizado por un codificador que comprende, por un segmento de la señal de audio: identificar un conjunto de picos espectrales; determinar una distancia S media entre picos en el conjunto; y determinar una proporción, PNR, entre un pico de la envolvente y una envolvente de umbral mínimo de ruido. El método comprende además la selección de un modo de codificación, fuera de una pluralidad de modos de codificación, basándose al menos en la distancia S media y la proporción PNR; y aplicar el modo de codificación seleccionado para la codificación del segmento de la señal de audio.
