Abstract

El objetivo de la invención es un aparato 2 descrito por un diagrama de bloques esquemático para procesar una señal de audio 4 para obtener una señal de audio procesada 6. El aparato 2 comprende un calculador de fase 8 para calcular valores de fase 10 por valores espectrales de una secuencia de tramas del dominio de la frecuencia 12 que representan tramas superpuestas de la señal de audio 4. Además, el calculador de fase 8 es configurado para calcular los valores de fase 10 sobre la base de la información sobre una envolvente en el dominio del tiempo objetivo 14 relacionada con la señal de audio procesada 6, de modo que la señal de audio procesada 6 tenga en al menos una aproximación la envolvente en el dominio del tiempo 14 y una envolvente espectral determinada por la secuencia de tramas en el dominio de la frecuencia 12..
