Abstract
Se describe un descodificador de matriz. Este descodificador surround de matriz de audio requiere procesamiento digital mínimo, útil en aplicaciones portátiles, particularmente en reproducción de un reproductor portátil que utiliza audífonos o dispositivo de virtualización (virtualizador). En una modalidad, realiza tomas panorámicas de entradas Lt y Rt a salidas asociadas con direcciones frontales en respuesta a una medida de la suma de Lt y Rt que es mayor que la medida de la diferencia entre Lt y Rt y realiza tomas panorámicas de Lt y Rt a salidas asociadas con direcciones traseras en respuesta a una medida de la suma de Lt y Rt que es menor que la medida de la diferencia entre Lt y Rt. Lt y Rt son modificados para desplazar la dirección de las señales reproducidas.
