Hi Junfeng,
For theory and to understand the problem you should have a look at the
references mentioned before, I attach the titles of some key studies:
B. S. Atal and M. R. Schroeder (1962) "Apparent sound source
translator", U.S. Patent, 3236949.

Reproduction". Journal of the Acoustical Society of America, vol. 50,
pp. 1109-1115.

Sound-Image Localization in Stereophonic Reproduction: Part II" Journal
of the Audio Engineering Society, vol. 30, pp. 719-722.

for playback of Head- Related Recordings in a 2-Speaker System"

P. A. Nelson, O. Kirkeby, T. Takeuchi, and H. Hamada (1997) "Sound
fields for the production of virtual acoustic images" Journal of Sound
and Vibration, vol. 204, pp. 386-396.
W. G. Gardner (1998) 3-D audio using loudspeakers. Boston: Kluwer
Academic Publishers.
D. B. Ward and G. W. Elko (2000) “A new robust system for 3D audio using
loudspeakers”, in Proceedings 2000 IEEE International Conference on
Acoustics, Speech and Signal Processing, vol. 2, pp. 781-784.
For the implementation I would say that the you can directly apply the
algorithm proposed by Kirkeby-Nelson for the inversion of your measured
crosstalk paths, which works quite well and you can also tune it to some
extent to your specific conditions by use of the regularisation parameter:
O. Kirkeby, P. A. Nelson, H. Hamada, and F. Orduna Bustamante (1998a)
"Fast deconvolution of multichannel systems using regularization" IEEE
Transactions on Speech and Audio Processing, vol. 6, pp. 189-94.
Especially in low-RT or anechoic conditions you should get very good
results either with synthesised or recorded binaural material. Beware of
strong reflections though, if you have them you have to correct these too..
Regards,
Archontis

Hello, all friends,
Is anyone working on binaural sound reproduction using loudspeakers?
To reproduce 3D sound using loudspeaker, cross-talk cancellation is needed,
as I know.
Does anyone know which the most-advanced cross-talk cancellation
technique/algorithm?
Does anyone have a sample program (source code) of binaural reproduction
using loudspeaker, which can share with me?
Great appreciation to all you.
Best regards,
Junfeng
