Phooey.....

His brief explanation of what "Surround Sound" is, is completely flawed. The audio is engineered with discrete channels that fade in/out from one another to create the "person walking by" effect he spoke of..... Perhaps I misunderstood it, but this looks more gimmicky than a Bose wave radio.

reminds me of those 'HD glasses'...

Prof. Choueiri explained that the key to his approach is "filtering" so that the left ear only hears the left speaker and the right ear only hears the right speaker. That's obviously not possible with five speakers in a surround system (unless you have five ears, of course

). I have no idea about the science behind his claim. And, it would seem to require that the listener be placed in a specific spot. But, the demonstration on the video of location imaging with two PC speakers is fairly impressive.

although its not "3D" doesnt timber matching attempt to give the listener better depth in the sound stage?

Can anyone say Carver C-9 Sonic Hologram or Polk Audio SDA technology? These two technologies are also crosstalk cancelation technologies (I still have a C-9 in my system). The Carver version required precise speaker positioning - an acoustically dead room, and for the user to sit in a specific place (and don't move your head). It works very well in my room. The SDA version while not a precise as the Carver tech - allowed you leeway in your seating position and worked quite well also (I've owned several pair of SDA speakers in the past and I loved them all).

The Carver can produce some stange effects though - extending the soundfield around your head (sounds coming out of walls or extending beyond walls, sounds coming from the floor front - rising to the center image and falling in front of you. It's very immersive - and its interesting on many recordings. At times however I will disengage the C-9. If it becomes too freaky and unnatural and scary - (like someone playing a small percussion instrument such as a triangle and they sound like they are sitting next to you) - if it gets like that ... off it goes.

Here is another site http://www.ambiophonics.org/index.html that dives into "3D" sound. Ambiophonics has been around for quite a while also. I see that they now offer PC programs (so you pc can serve as an ambiophonics processor). TAcT also has a hardware add-on unit that includes ambiophonics processing.

That's it! I am selling everything and will be getting the 3D stereo kit... NOT!!!!

chad_1138 · 11-17-2010, 06:31 PM

I was skeptical when I looked at the video, but it actually sounds really good for 2 speakers. The fly flying around your head was really impressive. The best thing is that it looks like it won't take any new equipment at home for this. It will be interesting to see what comes of it...

crackinhedz · 11-18-2010, 04:17 AM

Could be beneficial for TV speakers?

Q? · 11-18-2010, 04:31 AM

Actually I'm impressed, but I'm still not sure how the illusion is created, I swear there are hidden speakers behind me

The 3D Barbershop posted above only works on headphones because a headphone can create perfect isolation between the left and right ears.

What this professor is talking about is making a perfect left/right separation with just speakers in a room, which seems impossible if you think about it (sound waves are bouncing all over the room).

So this is definitely something new; the recording process ("binaural recording") is not new, but this type of playback is new.

Not new. See Cooper-Bauck Transaural, as just one example.

The recording technology was available a long time ago, but it only sounded 3D with a pair of headphones or earphones. It's really cool to see people are developing 3D speakers, there might be TVs coming in the future that has this 3D technology and it really cool!
