Does capsule quality matter? A comparisonstudy between spherical microphone arrays using different type of omnidirectional capsules


Simeon Delikaris-Manias, Vincent Koehl, Mathieu Paquier, Rozenn Nicol, and Jérôme Daniel


This 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.
