Designing High Spatial Resolution Microphones

Multichannel recording is one of the most important challenges of today's audio techniques. A good surround recording should provide at the same time good envelopment feeling, accurate localisation, a large sweet spot and respect for tones. Fourier-Bessel theory and advanced signal processing allow to obtain directivities designed from panning laws, which have been designed to optimally drive any multichannel layout. This paper presents the underlying concept of High Spatial Resolution, the spatial equivalent for High Fidelity, and points out why this is a key point to achieve high spatial quality. A very flexible and scalable technology providing High Spatial Resolution, as well as a high-performance 5.0 microphone featuring a compact array of 16 omnidirectional capsules are also presented.
