Abstract

Un aparato para la generación de una pluralidad de canales de audio para una primera instalación de parlante se caracteriza por un determinador de parlante imaginario, un calculador de distribución de energía, un procesador y un renderizador. El determinador de parlante imaginario está configurado para determinar una posición de un parlante imaginario no contenido en la primera instalación de parlante a fin de obtener una segunda instalación de parlante que contiene el parlante imaginario. El calculador de distribución de energía está configurado para calcular una distribución de energía desde el parlante imaginario hasta los otros parlantes en la segunda instalación de parlante. El procesador está configurado para repetir la distribución de energía a fin de obtener una información de mezcla descendente para una mezcla descendente desde la segunda instalación de parlante hasta la primera instalación de parlante. El renderizador está configurado para generar la pluralidad de canales de audio usando la información de mezcla descendente.
