Abstract

Se proporciona en la presente un aparato (100) para generar una señal de audio filtrada a partir de una señal de entrada de audio. El aparato (100) comprende un determinador de información de filtro (110) que es configurado para determinar información de filtro dependiendo de la información de altura de entrada donde la información de altura de entrada depende de una altura de una fuente de sonido virtual. Además, el aparato (100) comprende una unidad de filtro (120) que es configurada para filtrar la señal de entrada de audio para obtener la señal de audio filtrada dependiendo de la información de filtro. El determinador de información de filtro (110) es configurado para determinar la información de filtro usando la selección, dependiendo de la información de altura de entrada, de una curva de filtro seleccionada de una pluralidad de curvas de filtro, o el determinador de información de filtro (110) es configurado para determinar la información de filtro usando la determinación de una curva de filtro modificada modificando una curva de filtro de referencia dependiendo de la información de elevación.
