How strange, you disagree with my theoretical standpoint, yet agree with someone else agreeing with my theoretical standpoint, how embarrassing! You have just demonstrated your prejudice personality toward myself, and quite frankly should be ashamed of yourself, people come here to discuss things like this, and you have been nothing but a loser.

Yes, it's mainly the theoretical notion that I'm trying to get people to understand. When you say that surround tracks are recorded with 5,6,7 speakers in mind, could you expand on that a little? Maybe provide some references? I would be interested to know what it is about the recording process that enables surround sound to be more "realistic" than stereo.

What i'm saying is it doesn't matter how many sources of sound there is, we hear the real multidimensional world with just our two ears, the sound comes from EVERYWHERE, this is what makes our hearing multidimensional (also called a sound-stage). So if we only need two ears to perceive this sound-stage, is IS possible to re-create a stereo sound track to imitate the "real world sound". Just like we do with 3D movies and our eyes. You will find this much easier two understand if you compare it to vision, it's practically the same concept im getting at here.
That is quite different than the original question of, "Does surround sound actually work?" This thread has morphed from the original question to one that would be more aptly titled, "Aren't just two channels all that is needed for surround sound delivered through headphones?" And the answer to that question is theoretically yes. The answer to the title of this thread is also yes. But since the title is far from your point, respondents respond to the title, not your point.

From an article I recently read
Quote:

"For a listener sitting equidistant between the left and right speakers, and at least as far away from the speakers as the speakers are from each other, a three-dimensional sound-field is reproduced. That is, sounds are recreated pretty much anywhere within the boundaries of the imaginary stage. The voice of an actress standing in the center of the screen will sound as if itís coming from right between your speakers. If she should step ten feet straight back and three feet to the left then her voice will sound like itís ten feet behind your speakersóyes, even if your front wall is only 3 feet behind the speakersóand three feet left of center.

Now, for listeners not seated equidistant from the left and right speakers, sounds still seem to come from this imaginary stage area, but the soundsí locations are skewed towards whichever speaker is closer. These locations are not the ones the recording engineer intended. Think again about the actor speaking from center-stage. The listener who is seated equidistant between the speakers will hear that voice coming from center stageóas intended. Listeners seated closer to the right speaker will hear that actors voice coming from somewhere to right of where the actor is standing. Truth be told, only audiophiles care about this sort of spatial accuracy."
That is the key and real advantage of surround sound - it gives spatial accuracy of a far greater precision than stereo.

from another article
Quote:
Is it not possible to simulate real world sound using just two
audio sources?

No. All real musical events are heard in the context of the acoustics
of the performing space. You cannot reproduce that space with only
two sources.

Because in a real musical performance, the sound isn't just coming from
two directions; it's coming from many directions as it bounces off
walls, ceilings, floors, and audiences. By having more speakers, we can
better simulate the sound as it was in the original hall (or in the
space the recording engineer attempted to simulate).

By the way, the reason 2-channel became dominant has nothing to do with
the fact that we have two ears. It's just that back at the dawn of
stereo, nobody had a practical way to get more than two tracks into a
record groove. It was just a technical compromise at the time. (There
were already recordings with more than two channels.)

We have been in the gaming headset business a long time, so we know there are (mis)conceptions and (mis)information about surround sound and stereo sound, especially as they pertain to headsets. We have a strong point of view on the subject, so we wanted to share it.

First things first, if youíre like most people, you have two ears. You donít have six or eight different ears in various positions around your head yet, still, you can tell where sounds originate. Thatís because, as far as your brain is concerned, the only type of sound that exists in this world is stereo sound. Your brain takes all the signals your ears send to it and makes sense of them. And the way that our brains can tell where sound originates is by use of some pretty amazing biological computation that can tell which ear heard the sound first, how many surfaces it reflected off of, and how much it decayed since it was made. Your brain essentially functions like a surround sound decoder, only itís the most powerful one we know of.

Now, on to the part about headsets. Itís not uncommon to hear people assert that when you listen to stereo, you canít hear the sounds that are in front of you or behind you. Thatís just not true. You donít lose any sounds just because youíre listening to stereo. Every sound, no matter whether itís in front of you, behind you, underneath you, or inside of you in the game will be played through a stereo headset.

The difference between stereo and surround sound Is something called spatial accuracy. Letís say youíre playing a first person shooter, and thereís a sound in front of you and off to the right, maybe at about one oíclock. In a surround sound headset, that audio is going to sound more off in the distance, and itís going to be more accurately nuanced from left to right. In a stereo headset, it will sound more like itís ďinside your head,Ē and a little off to the right. In a surround sound headset, if that sound were coming from behind you, it would sound more like it was really coming from behind your head. In a stereo headset, it would just sound a bit quieter than if it were in front of you, and less like it were really behind you.

Is surround sound better? Well, yes ó we think it is. But that doesnít mean that stereo is bad. There is good stereo and bad stereo, just like there is good and bad surround sound. Ever sit in front of a TV and play a game through the TVís speakers? You can barely tell left from right, much less front from back. And just forget about nuanced differences in sound. But, thatís stereo, too.

When we make a stereo headset our goal is always to make a great stereo headset. A headset that will give you awesome clarity and balance, a headset thatís tuned well, and isolates your left from right so thereís not crossover that confuses your brain. With a well-made stereo headset, you will still have a great audio experience.
Once again surround sound gives improved spatial accuracy- this does not mean you don't get directional 'clues' form stereo just that the soundfield accuracy is improved with surround sound vs 2ch stereo.

I find this thread tiresome. But, rbinck, as a moderator, are you OK with shnabz calling me "too dumb/ignorant" and referring to another poster as "nothing but a loser"?

I started to laugh at that post then realized I wasn't in the gaming forum. :
