Computation of spherical sector harmonics norm with application to blind source separation [PDF]

open access: yesJASA Express Letters, 2023
Spherical microphone arrays (SMAs) are widely being used for source localization and separation. However, it is uneconomical to build a full SMA when sources are present in restricted regions of environment.
