Abstract

Las modalidades proporcionan un procesador digital que comprende un extractor de la porción ambiental y una etapa de procesamiento del efecto espacial. El extractor de la porción ambiental se configura para extraer una porción ambiental de una señal de múltiples canales. La etapa de procesamiento del efecto espacial se configura para generar una señal del efecto espacial basada en la porción ambiental de la señal de múltiples canales. El procesador digital se configura para combinar la señal de múltiples canales o una versión procesada de la misma con la señal del efecto espacial.
