Abstract

A recently developed technique known as analogue transformation acoustics has allowed the extension of the transformational
paradigm to general spacetime transformations under which the acoustic equations are not form invariant. In this paper, we review
the fundamentals of analogue transformation acoustics and show how this technique can be applied to build a device that increases
the density of events within a given spacetime region by simultaneously compressing space and time.
