Spherical fraction beamforming
WebNov 1, 2024 · In particular, spherical microphone arrays (SMAs) have been widely used for beamforming [5], [6], [7], [8], [9]. The widespread application of SMAs is due to ease of array signal processing in spherical harmonics (SH) domain without any spatial ambiguity [10].
