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 (s

You can still find the devices around(they were
crosstalk cancellation processors).

I have a Carver C-9 Sonic Hologram unit that I bought on Ebay for about
$80. It's a nice little demo piece, but limited in its application.
That said, it's biggest problem is noise. Of course it's all analogue
and built around -10 dbm levels. And all those capacitors are now very
old.

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.
P. Damaske (1971) "Head-Related Two-Channe
I forgot to mention that is also practical if you keep your loudspeakers
at close spacing (like 10deg) rather than a stereo setup, which gives
you a better performance for a wider frequency range, a technique that
Kirkeby and Nelson patented as the "stereo-dipole".

PLEASE NOTE that I predate Keele on this barrier idea by quite a few
years.
I was being modest and not mentioning myself because the idea of a
physical barrier is so trivial
that it ought to be beneath anyone's dignity to accept "credit" for it.
But if credit were to be assigned(and in the

I am delighted to see a lively discussion of crosstalk cancellation

working on XTC for the past few years.
I would like to add a few comments that may be relevant to the discussion.

Hi list,
An associate has told me of this discussion and suggested that I respond, so I
have resubscribed to the list to do so. It seems that perhaps a refresher in

It is hardly heavy science, but people who have not
tried it are always pleasantly surprised by the barrier
results. Even if one does barrier in front only, and even
a small one like holding a pillow to your nose edge on,
the cleanliness of the sound is surprising.
It is debatable whether the ste
