What is Imaging?

When you can pick out/imaagine in space where each sound is apparently coming from. Say a massed choir.. You can hear each voice occupying a separate position in the space between/around/squeezed, wider, narrower, all mushed to Hell... etc. Vaguely from somewhere between the speakers.. maybe?
That is imaging. Good or bad.

According to this audio glossary:

Imaging - The sense that a voice or instrument is in a particular place in the room.

Tricks, illusion and deception. Convincing and convenient perception.
