Abstract

Un procesador para el procesamiento de una senal de audio (200), que comprende: un analizador (202) para la derivacion de una senal de control de la ventana (204) desde la senal de audio (200) que indica un cambio de una primera ventana asimetrica (1400) a una segunda ventana (1402), o que indica un cambio de una tercera ventana (1450) a una cuarta ventana asimetrica (1452), en el que la segunda ventana (1402) es mas corta que la primera ventana (1400), o en el que la tercera ventana (1450) es mas corta que la cuarta ventana (1452); un constructor de la ventana (206) para la construccion de la segunda ventana (1402), por el uso de una primera porcion de solapamiento (800) de la primera ventana asimetrica (1400), en el que el constructor de la ventana (206) esta configurado para determinar una primera porcion de solapamiento (1000) de la segunda ventana (1402) por el uso de una primera porcion de solapamiento truncada de la primera ventana asimetrica, o en el que el constructor de la ventana esta configurado para calcular una segunda porcion de solapamiento (1330) de la tercera ventana (1450) por el uso de una segunda porcion de solapamiento truncada (814) de la cuarta ventana asimetrica (1452); y un windower (208) para la aplicacion de la primera y la segunda ventana o la tercera y la cuarta ventana para obtener porciones de la senal de audio mostradas en ventanas (210).
