Here's how it works. Quick speech recording, played against a constant
reverb impulse (a local church, in fact), repeated five times with the
ratio of direct and reverberant sound changed each time - final one is
reverberant only.

Obviously greatly exaggerated for illustration.

OK, thanks. I see I have to add reflections to the list of things
(timbre, amplitude and image width) which yield depth information.

So the listening room will indeed impose its own imprint on depth
perception (as will things like equipment microphony).
