The researchers whose trusted networks rank it highest, strongest advocate first. Every researcher gets a different order.

A Consolidated Perspective on Multimicrophone Speech Enhancement and Source Separation (2017, unknown): “Spherical microphone arrays [129], [130] have also attracted attention, due to their ability to symmetrically analyze tridimensional sound-fields [131]–[133] (see also dual-radius spherical arrays [134]).”
Analysis and design of spherical microphone arrays (2005, methodology): “The analysis in this paper is based on spherical-harmonics decomposition, or the spherical Fourier transform, and could therefore, directly apply to the recently studied spherical-harmonics based microphone arrays [1]–[3], [5]–[7].”
Three-Dimensional Surround Sound Systems Based on Spherical Harmonics (2005, unknown): “(1) by Y l q (␪, ␾)* and integrating over the sphere [9], [43] yields A n m ͑k͒ = 1 j n ͑kr͒ ͐ 0 2␲ ͐ 0 ␲ p͑r, ␪, ␾, k͒ Y n m ͑␪, ␾͒* sin͑␪͒ d␪ d␾.”
