Abstract

Un aparato para la manipulación de una señal audio que comprende un evento transitorio comprende un sustituidor de señal transitoria configurado para sustituir una porción de señal transitoria que comprende el evento transitorio de la señal audio por una porción de señal de sustitúción adaptada a las características de energía de señal de una o varias porciones de señal transitorias de la señal audio, o a las características de energía de señal de la porción de señal transitoria, para obtener una señal audio de transitorios reducidos. El aparato comprende también un procesador de señal configurado para procesar la señal audio de transitorios reducidos, para obtener una versión procesada de la señal audio de transitorios reducidos. El aparato comprende también un reinsertador de señal transitoria configurado para combinar la versión procesada de la señal audio de transitorios reducidos con una señal transitoria que representa, de forma original o procesada, un contenido transitorio de la porción de señal transitoria.
