There is a lagged autoregressive technique used in forensic analysis that allows 3d reconstruction using 1d (mic) sound.

A CNN should be able to back that out too, and do other things like regenerate a 3d space. In the right, high-fidelity, acoustic tracks could be the spatial information to reconstruct a stage and a performance. It would be neat/beautiful/(possibly very powerful) to back video out of audio in that way.
