Abstract

Un aparato para generar una descripción de campo de sonido a partir de una señal de entrada que comprende al menos dos canales comprende: un analizador de señal de entrada (600) para obtener datos de dirección y datos de difusión de la señal de entrada; un estimador (620) para estimar una primera medición relacionada con energía o amplitud para un componente omnidireccional derivado de la señal de entrada y para estimar una segunda medición relacionada con energía o amplitud para un componente direccional derivado de la señal de entrada, y un generador de componentes de sonido (750) para generar componentes de campo de sonido del campo de sonido, en donde el generador de componentes de sonido se configura para realizar una compensación de energía del componente direccional utilizando la primera medición relacionada con energía o amplitud, la segunda medición relacionada con energía o amplitud, los datos de dirección y los datos de difusión.
