Abstract

El presente documento es concerniente con el procesamiento de señales de audio, en particular con un aparato y método correspondiente para mejorar la señal de audio de un receptor de radio estereofónico de FM. En particular, el presente documento es concerniente con un método y sistema para reducir el ruido de una señal de radio estereofónica de FM recibida. El aparato (2) configurado para reducir el ruido de una señal de radio de FM de multicanal recibida es descrito, en donde la señal de radio de FM de multicanal recibida es representable como una señal media recibida y una señal lateral recibida. El aparato (2) comprende una unidad de determinación de parámetros (77) configurada para determinar uno o más parámetros indicadores de una correlación y/o descorrelación entre la señal media recibida y señal lateral recibida y una unidad de reducción de ruido (79) configurada para generar la señal lateral de ruido reducido a partir de la señal media recibida y no de la señal lateral recibida utilizando el uno o más parámetros.
