Mono could also be understood as 4D (or 3D space) in the sense that one can easily recognise certain acoustic spaces with a mono recording. such as a recording of someone talking in a church. There will be very clear cues, within that recording, that the voice was captured within a large

Another point that is interesting, in considering the cognitive dimension of spatial perception, is that some processes involve the identification of a sounding object, and some do not. The recognition of an over-simplified mono reverb algorithm, as an "Icon" of the sound of a large space, require

What's interesting is that the demo is actually totally cheating. It relies on cognitive cues, perhaps even more than on presenting realistic stimuli. It does this in two ways: Firstly, it extensively uses symbolism, through language, to create expectations of spatial experience... "now over here
