Worst-case performance optimization for spherical microphone array modal beamformers

The performance of conventional spherical microphone array modal beamformers is known to degrade in the presence of array errors. White noise gain control has been widely used to control the robustness of modal beamformers, but it is not clear how to properly choose the white noise gain parameters b...
