Abstract

Se presenta un aparato (100) para reproducir un objeto de audio asociado a una posición. El aparato (100) comprende un calculador de distancia (110) para calcular distancias de la posición hasta los parlantes o para leer las distancias desde la posición hasta los parlantes. El calculador de distancia (110) está configurado para adoptar una solución con la distancia más corta. El aparato (100) está configurado para reproducir el objeto de audio utilizando el parlante que corresponde a la solución.
