Abstract
Un método para conservar informacion perceptivamente relevante que no es de habla en una senal de audio durante la codificacion de la senal de audio comprende efectuar una primera determinacion en cuanto a si la senal de audio comprende informacion de habla o de ruido, efectuar una segunda determinacion en cuanto a si la senal de audio incluye informacion que no es de habla y si es perceptivamente relevante para el oyente, y anular selectivamente dicha primera determinacion, en respuesta a dicha segunda determinacion. Un aparato que comprende un clasificador para recibir la senal de audio es utilizado para efectuar una primera determinacion en cuanto a si se considera que la senal de audio comprende informacion de habla o ruido, comprende además un detector para recibir la senal de audio y efectuar la segunda determinacion en cuanto a si la senal de audio incluye informacion que no es de habla y sí perceptivamente relevante para el oyente, y logica acoplada al clasificador y al detector, tiene una salida para indicar si la senal de audio incluye informacion perceptivamente relevante, siendo la logica operable para proporcionar selectivamente en la salida la informacion indicativa de la primera determinacion y que también responde a la segunda determinacion para anular selectivamente en la salida la informacion indicativa de la primera determinacion.
