Archontis Politis, Ville Pulkki
Matlab/Octave routines implementing the VBAP method for sound spatialization, triangulation of loudspeaker setups, VBAP-based sound spreading and some variants.
Matlab/Octave routines simulating array responses for sensors with arbitrary directional characteristics, or sensors placed on top or at a distance from a rigid spherical/cylindrical scatterer.
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.
