> In any case it's essentially a spatial sense, not a temporal one,

What do you mean by that distinction?

If you contrast vision and hearing, vision is about things with spatial extent (the 2-D/3-D scene you are looking at), and I think the subjective experience of visual attributes like color comes directly from that - color being fundamentally a spatial attribute that differentiates surfaces (as you scan your eyes around), with this providing a common base quale of experiencing any color - the experience of a sensed attribute that changes, or not, as we scan a scene.

In contrast, hearing is a temporal sense primarily about temporal sequences of changing patterns of sensed frequencies, and we experience this as sensed attributes that change, or not, over time (and which may surprise us, or not, by matching previously experienced temporal sequences).

I think echolocation is more like vision in this regard, perhaps more like the flashlight example, but an input that varies spatially rather than temporally.
