Abstract
Un método para la ampliacion de senales de audio que comprende obtener (222) una primera senal de audio de un primer elemento de microfono físico y obtener una segunda senal de audio de un segundo elemento de microfono físico. Las senales de audio se procesan en red (226) para generar un elemento virtual lineal de primer orden y un elemento virtual no lineal de orden par. El procesamiento en red (226) incluye combinar el elemento virtual lineal de primer orden y el elemento virtual no lineal de orden par para generar una senal de audio direccional con un haz de audio principal.
