Hi, actually, no, i am not referring to crosstalk at all. let me say it this way. in nature, there are not two distinct sound sources placed some feet across from each other, with a fixed radiation pattern toward you, as is with two speakers.
this is first and foremost the biggest flaw of stereo, despite the ability to "trick" your ears as far as left right imaging and only a small amount of depth and virtually no height information (all this on standard recordings, not "trick" recordings). It nerver sounds real, only does so when you imagine it so. And, on this forum, only one person owned up to claiming he heard a stereo system that sounded real.
so, what does true binaural do, it presents sound to each ear, thus more natural than some speakers talking at you. True binaural is using a dummy head, with mics where your ears are. its not perfect, for many technical reasons, but it is natural, as it captures sounds the way your ear do basically. That is it captures height, depth, width, and even from behind you. it is simply the more natural, and as far as replication, as far as not moving your head or not experiencing physical sound pressure waves on your body, the most accurate replicattion system.
stereo tries to bring the event to you, binaural brings you to the event.....a simple sentence, but you must understand that to understand what i am talking about.
cheers.
