Abstract

Un aparato para obtener un parámetro que describe una variación de una característica de señal de una señal sobre la base de parámetros del dominio de la transformada real que describen la señal de audio en el dominio de la transformada comprende un determinador de parámetro. El determinador de parámetro está configurado para determinar uno o más parámetros de modelo de un modelo de variación del dominio de la transformada que describen una evolución de los parámetros del dominio de la transformada en dependencia de uno o más parámetros de modelo que representan una característica de señal, tal que un error de modelo, que representa una desviación entre una evolución temporal modelada de los parámetros del dominio de la transformada y una evolución de los parámetros del dominio de la transformada real, es llevado por debajo de un valor umbral predeterminado o minimizado.
