the human hearing mechanism encodes height information based on frequency contouring caused by the shape of the ear. there is a tone map in the brain that instantly "translates" certain directional sounds as "higher" or "lower." SOME stereo music recordings contain enough of this information, a FEW of them. i have heard it demonstrated on the LEDR [Listening Environment Diagnostic Recording] on a Chesky test disc, with the synthetic cabasa rising above one speaker and sailing across the ceiling to the other speaker, as well as sailing backwards.
Soundstage and image height, does it exist?
On another site, there is a discussion on soundstage, and there are a few people clamming, that, since there is no vertical information encoded on stereo recordings, that soundstage height does not actually exist. It is a product of our minds filling in missing information.
Are they correct?
Please explain your position, with as much technical details as you feel needed.
