Abstract

Procesador de audio (10) que comprende una interfaz de entrada, una interfaz de detector (32), una mezcladora (22) y una interfaz de salida. La interfaz de entrada recibe por lo menos dos canales de audio de entrada (121, 122), cada canal de audio de entrada (121, 12) está asociado con una posición de reproducción predeterminada de por lo menos dos parlantes (261, 262) en por lo menos un eje de parlante (16). La interfaz de detector (32) recibe una señal de posición (18) que indica una información sobre una posición de por lo menos dos parlantes (261, 262) con respecto a un eje de oreja (20) de un oyente (28), en donde el eje de oreja (20) y el por lo menos un eje de parlante (16) tienen un ángulo (36) entre sí, que es mayor que 0° y menor que 1800. La mezcladora (22) mezcla por lo menos dos canales de audio de entrada (121, 122) para obtener por lo menos dos canales de salida (141, 142), dependiendo de la señal de posición (18), de tal manera que una porción del segundo canal de audio de entrada (122) en el primer canal de salida (141) para un primer ángulo (36) entre el eje de oreja (20) y el eje de parlante (16) es mayor que una porción del segundo canal de audio de entrada (122) en el primer canal de salida (141) para un segundo ángulo (36) entre el eje de oreja (20) y el eje de parlante (16), en donde el primer ángulo (36) es mayor que el segundo ángulo (36) . Asimismo, una porción del primer canal de audio de entrada (121) en el segundo canal de salida (142) para el primer ángulo (36) es mayor que la porción del primer canal de audio de entrada (121) en el segundo canal de salida (142) para el segundo ángulo (36), en donde el primer ángulo (36) es mayor que el segundo ángulo (36). La interfaz de salida emite por lo menos dos canales de salida (141, 142) hasta por lo menos dos parlantes.
