Classification: CPC H | IPC H

Claim 9:
10. The device according to claim 9, wherein the processing unit is configured to decompose the signals coming from the microphone capsules, into the spherical harmonics associated with the retained ambisonic components, using a matrixing of the type:
b=C EYGs, where:
b is a vector matrix containing the retained ambisonic components,
C is a real constant,
E is a diagonal matrix containing radial equalization filters of each capsule,
Y is a matrix containing the spherical harmonics with which the retained ambisonic components are associated, and
G is a diagonal matrix containing integration weights of a Gauss-Legendre grid for each of the capsules,
s being a vector containing signals coming from the capsules.
