Robust 3-D Sound Source Localization Using Spherical Microphone Arrays
Spherical arrays are gaining increased interest in spatial audio reproduction, especially in Higher Order Ambisonics. In many audio applications the sound source detection and localization is of crucial importance, urging for robust localization methods suitable for spherical arrays. The well-known direction-of-arrival estimator, the ESPRIT algorithm, is not directly applicable to spherical arrays for 3-D applications. The eigenbeam ESPRIT (EB-ESPRIT) is based on the spherical harmonics framework and is especially derived for spherical arrays. However, the ESPRIT method is in general susceptible to errors in the presence of correlated sources and spatial decorrelation is not possible for spherical arrays. In our new implementation of spherical harmonics-based ESPRIT (SA2ULA-ESPRIT) the robustness against correlation is achieved by spatial decorrelation incorporated directly in the algorithm formulation. The simulated performance of the new algorithm is compared to EB-ESPRIT.
