Spatial Decomposition by Spherical Array Processing Academic Article uri icon


  • Spherical microphone arrays have the advantageous property of rotational symmetry and are, therefore, most suitable for capturing and analyzing three-dimensional sound fields. A fundamental step in the spatial processing of microphone signals is to extract the plane waves that compose the measured sound field in an operation referred to as plane-wave decomposition (PWD; Meyer and Elko, 2002; Abhayapala and Ward, 2002; Gover et al., 2002; Rafaely, 2004). PWD provides a generic spatial representation of sound fields and …
