Abstract
Un método que comprende: recibir al menos tres señales de audio de micrófono, comprendiendo las al menos tres señales de audio de micrófono al menos dos señales de audio de micrófono cercanas generadas por al menos dos micrófonos cercanos localizados cerca de una fuente de audio deseada y al menos una señal de audio de micrófono lejana generada por un micrófono lejano localizado más allá de la fuente de audio deseada que los al menos dos micrófonos cercanos; generar una primera señal de audio procesada basándose en una primera selección de las al menos tres señales de audio de micrófono, siendo la primera selección a partir de las señales de audio de micrófono cercanas; generar al menos una señal de audio procesada adicional basándose en al menos una selección adicional de las al menos tres señales de audio de micrófono, la al menos una selección adicional de las al menos tres señales de audio de micrófono, siendo la segunda selección de todas las señales de audio de micrófono; determinar a partir de la primera señal de audio procesada y de la al menos una señal de audio procesada adicional, la señal de audio con una mayor supresión de ruido.
