Does capsule quality matter? A comparison study between spherical microphone arrays using different types of omnidirectional capsules

7 pagesInternational audienceThis study presents an objective comparison between two rigid spherical microphone arrays of the exact same size but differing by the type of capsules. An analysis of the simulations and the encoding process is presented and known limitations of the spherical arrays are discussed such as the degraded reconstruction of the spherical harmonics due to the size of the sphere and the size and number of the capsules

Multi-point nonlinear spatial distribution of effects across the soundfield

This paper outlines a method of applying non-linear processing and effects to multi-point spatial distributions of sound spectra. The technique is based on previous research by the author on non-linear spatial distributions of spectra, that is, timbre spatialisation in the frequency domain. One of the primary applications here is the further elaboration of timbre spatialisation in the frequency domain to account for distance cues incorporating loudness attenuation, reverb, and filtration. Further to this, the same approach may also give rise to more non-linear distributions of processing and effects across multi-point spatial distributions such as audio distortions and harmonic exciters, delays, and other such parallel processes used within a spatial context
