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.

It exists but recording as well as room and equipment dependent. My reason for saying this, I can hear it in my room at times. Certainly the depth, left, right and center aspects of sound stage are much more frequently present. When I say height its not that the wall of sound is high as well as wide it is I can hear specific sounds as coming from a tall specific spot within the sound stage.

There is no soundstage image height or image at all. It's just your brain trying to make sense of what it's perceiving its a trick an illusion. Just like when you watch all those non-moving fixed images on your TV your brain makes it seem like real motion is going on.

Then how do you explain Northwestern's LEDR recording, already mentioned several times on this thread?

The track in question, starts with a tone in the left speaker, which then moves straight UP to at least 8' or more feet up, moves across to directly over the top of the right speaker, then down to the speaker level. 

Yes, this track was created specifically to exaggerate this effect, but if speakers were incapable of producing height, please explain this track.

So far, this same phenomena occurs on every system I've played it on. Even speakers not known for their great imaging. 

Stereo is an illusion imaging is a trick it’s not there your brain just thinks it is. Just like your brain thinks a moving picture exists when it’s all just still images flashed at a high rate just like you perceive motion in an animated film. If you move off center the image vanishes because it’s not there. If I had only 1 ear would I hear this movement of sound? if you played only 1 speaker would it still be there? No, it wouldn’t because it was never there in the 1st place. During playback, the listener’s brain uses those subtle differences in timing and sound level to triangulate the positions of the recorded objects.
