Low-Complexity Steered Response Power Mapping based on Nyquist-Shannon Sampling.
calc_FD_GCC.py computes frequency domain GCC. calc_SRP.py computes SRP approximation. calc_SRPconv.py computes conventional SRP. calc_STFT.py computes the STFT. calc_sampleParam.py computes sampling period and number of samples within TDOA interval. coord_loc_1_8.mat location of the sources. coord_mic_array.mat coordinates of the microphone array. gen_searchGrid.py generates search grid. main.py defines the configuration, loads microphone signals, performs conventional and low-complexity SRP and computes approximation and localization errors. This is done for eight different source locations.
