Abstract
Disclosed is a method of reconstructing a sound field. The method comprises receiving measured values of a first acoustic quantity measured at a set of measurement locations; computing a second acoustic quantity for a target location from a superposition of plane waves. The method comprises storing a set of representations of interpolations of respective functions, each function being a function of two or less input parameters; and computing comprises computing each of a set of correlation functions, each correlation function being indicative of a correlation of the plane waves at a first one of said measurement locations with the plane waves at a second location, as a linear combination of values obtained from the set of representations of interpolations.
