Spherical Array Processing Library

Archontis Politis

Matlab/Octave routines implementing a range of acoustical signal processing operations for spherical microphone arrays, such as obtaining spherical harmonic signals, generating signal-independent and adaptive beamformers in the spherical harmonic domain, estimating directions-of-arrival from prominent sound sources, and analyzing sound field diffuseness.
