Abstract: Abstract High-resolution CLEAN-SC (HR-CLEAN-SC) with spherical microphone arrays is a promising technology for panoramic sound source identification. To further enhance the ability to resolve multiple closely spaced sources at low frequencies, filter-and-sum based HR-CLEAN-SC is… read more here.
