Abstract
A method of representing a sound field includes the steps of acquiring measurement signals (c.sub.n) which are delivered by simple sensors (2.sub.n) 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) by applying the encoding filters to the signals (c.sub.n), in order to determine a finite number of representative coefficients over time and in the three-dimensional space of the sound field (P).
