Abstract
Un aparato para procesar una señal de audio que comprende una secuencia de bloques (114) de valores espectrales comprende: un procesador (100) para procesar la secuencia de bloques utilizando por lo menos un valor de modificación (102) para un primer bloque para obtener una primera señal obtenida como resultado con efecto aliasing reducido o sin efecto aliasing en un margen de solapamiento (170) y utilizando por lo menos un segundo valor de modificación diferente (106) para un segundo bloque de la secuencia de bloques para obtener una segunda señal obtenida como resultado con efecto aliasing reducido o sin efecto aliasing (108) en el margen de solapamiento (170); y un combinador (110) para combinar la primera señal obtenida como resultado (104) y la segunda señal obtenida como resultado (108) en el margen de solapamiento (170) para obtener una señal procesada (112) correspondiente al margen de solapamiento (170).
