Abstract

Un proceso para convertir M canales de entrada de audio, que representan un campo acustico, en N canales de salida de audio, que representan el mismo campo acustico, en donde cada canal es un solo flujo de audio que representa audio que llega desde una direccion, M y N son numeros enteros positivos, y M es al menos 2, genera uno o mas conjuntos de canales de salida, en donde cada conjunto tiene uno o mas canales de salida. Cada conjunto esta asociado con dos o mas canales de entrada espacialmente adyacentes, y cada canal de salida en un conjunto es generado mediante un proceso que incluye determinar una medida de la correlacion de los dos o mas canales de entrada y las interrelaciones de nivel de los dos o mas canales de entrada. La figura mas representativa de la invencion es la unica figura 1.
