This tendency is called the illusionary effect created by a particular terminology. Coz i still havent got the answer to the question that i have asked. If simulated 5.1 channel gives u the same output like real, then whats the difference?If in a scene theres a cycle passing from behind the subject & u actually turn behind to see if there was a cycle passing along......what more do u want? That damn sound is just moving from ur rear left to the rear right. The front speakers are damn silent. If that effect can be simulated, then what is Real?
