Abstract

Un metodo para mejorar la percepcion espacial de multiples canales de sonido, cuando son reproducidos por dos bocinas, localizadas en general frontalmente con respecto a los escuchas, cada canal representa una direccion , aplica a la bocina algunos de los canales, tales como los canales de sonido que representan direcciones diferentes a las direcciones frontales, con un procesamiento por audifonos y cancelacion de diafonia, y aplica a las bocinas, los otros canales de sonido, tales como los canales de sonido que representan direcciones frontales sin procesamiento por audifonos y cancelacion de diafonia. El procesamiento por audifonos incluye aplicar HRTF direccionales a canales aplicados a las bocinas con un procesamiento por audifonos y cancelacion de diafonia y puede incluir tambien la adicion de reflexiones simuladas y/o de tonalidad artificial a canales aplicados a las bocinas con procesamiento por audifonos y cancelacion de diafonia. La figura mas representativa de la invencion es la numero 2.
