This seems like the essence of the problem in creating (the illusion of) a 3D soundstage. Without height information the soundstage can, at best, be two dimensional. The fact that our ears are arranged on an axis running from left to right, and we don't have a third ear on a vertical axis, means that vertical placement of REAL sounds must be achieved through a different mechanism from that which allows us to place sounds laterally. I'd guess that the mechanism that we use for vertical placement depends partly on sound transmission through our skulls, and partly on subtle differences due to the shape of our ears. A sound from above us travels through different parts of our skull and ear than a sound from below us, and experience allows us to differentiate these effects. If this is true, then in theory it ought to be possible to reproduce a sound that sounds like it has travelled through different parts of the skull and ear, but I very much doubt that anyone has managed to achieve a proper understanding of these differences so that they can be, effectively, added to a recording. That being the case, I'd have to agree that any illusion of height coming from stereo speakers must be due to our brains creating a mental image of the performers. In fact, that correlates somewhat with my own experience - the soundstage becomes a lot clearer once I let myself get carried away and actually try to picture the performers in front of me. Moreover, I think that with a small effort of will I can imagine them in different places (depths, heights) and maintain the illusion of this new arrangement. -- chill ------------------------------------------------------------------------ chill's Profile: http://forums.slimdevices.com/member.php?userid=10839 View this thread: http://forums.slimdevices.com/showthread.php?t=93092 _______________________________________________ audiophiles mailing list [email protected] http://lists.slimdevices.com/mailman/listinfo/audiophiles
