Abstract

A method of representing a sound field includes the steps of acquiring measurement signals (c<SUB>n</SUB>) which are delivered by simple sensors (2<SUB>n</SUB>) that are exposed to sound field (P) determining encoding filters which are representative of at least the structural characteristics of the sensors and processing the measurement signals (c<SUB>n</SUB>) by applying the encoding filters to the signals (c<SUB>n</SUB>), in order to determine a finite number of representative coefficients over time and in the three-dimensional space of the sound field (P).
