The pinhole concept is a description that proposes to reduce the nature of the action at the foundational level to "almost" discrete
(the smile is because "almost discrete" is intended to attract your attention to the fact that it is not actually discrete). But still, the overriding action at that level is continuous relative to the medium. The thing that makes it have a "almost discrete" characteristic is the time delay between the convergence of expanding wave energy densities (colliding pressures), and the emergence of a new spherical out flowing pressure wave from those convergences.
That time delay represents unseen action at the foundational level where the wave energy density of the parent waves is participating in a compression of the foundational medium. That action appears as a time stoppage when viewed from a theoretical perspective close to the scene where the compression is taking place. You can't see the compression of the medium, and the wave action of the parents appears to slow to a near stop in that tiny overlap space, but continuous action is still occuring in the medium at that location.
