AB  - Many techniques have already been developped concerning surround sound recording, and this issue turned out to be a challenge, without a comprehensive theory. In this paper, an approach based on a full 3D acoustic field theory and using a 3D microphone array is presented. Our research works have lead to a new spatial digital processing technique allowing the use of freely positioned capsules of any type, such as omnidirectionnal, bidirectionnal, cardiod ones. This technique can be seen as an extension of full-sphere generalized Ambisonic providing a spatial resolution never reached before, but neither requires high-order directivity capsules nor assumes that all capsules are coincident. The theory has been validated with a full-sphere 3rd-order prototype using 24 omnidirectionnal capsules. A 5th-order directivity multichannel 5.0 microphone is also presented.
