Abstract

Un método de codificación del dominio de tiempo/dominio de frecuencia unificados y un dispositivo para codificar una señal de sonido de entrada comprenden un clasificador de la señal de sonido de entrada en una de una pluralidad de categorías de señales de sonido que comprenden una categoría de tipo de señal poco clara que muestra que la naturaleza de la señal de sonido de entrada es poco clara. Uno de entre una pluralidad de submodos de codificación se selecciona para codificar la señal de sonido de entrada si la señal de sonido de entrada está clasificada en la categoría del tipo de señal poco clara. Un codificador mixto de dominio de tiempo/dominio de frecuencia codifica la señal de sonido de entrada usando el submodo de codificación seleccionado. El codificador mixto de dominio de tiempo/dominio de frecuencia comprende un selector de bandas de frecuencia y un asignador de bits para seleccionar bandas de frecuencia para cuantificar y para distribuir un presupuesto de bits disponible para cuantificación entre las bandas de frecuencia seleccionadas. También se proporcionan el decodificador y el método de decodificación de señales de sonido correspondientes.
