Abstract

Un aparato para derivar una información direccional a partir de una pluralidad señales de micrófono o a partir de una pluralidad de componentes de una señal de micrófono, en donde se asocian diferentes direcciones de orientación efectiva de micrófono con las señales de micrófono o componentes, comprende un medio de combinación configurado para obtener un valor de magnitud a partir de una señal de micrófono o un componente de la señal de micrófono. El medio de combinación está configurado además para combinar elementos de información de dirección que describen las direcciones efectivas de orientación de micrófono de modo que se pondere un elemento de información de dirección que describe una dirección efectiva de orientación de micrófono dada en dependencia del valor de magnitud de la señal de micrófono o del componente de la señal de micrófono asociado con la dirección efectiva dada de orientación de micrófono, para derivar la información direccional.
