Sound source Localization using an eigth-microphone Array (UMA-8 from MiniDSP)
test_positions.m
needs data/test_positions_mic_check_[0-2].m4a (or its matlab version). plots the positions of the microphone and the test file.The right positioning was found to be in test_positions_mic_check_2.m4a
Methods used in this project are stored in /methods. They stem from /ext but they are modified. srphat has been modified to improve the performance significantly.
- /method_1: modified file is src/methods/method_1_classical/srpphat_jose_modified_1.m
- /method_2: uses an heuristic approach to reduce the time taken for the grid search using stochastic method.
- method_1_2_estimate.m which creates the output for both methods.
- method_1_preliminarytest.m is testing the implementation of method_1 with my own audio sources and micrphone structure.
Utils/ store some auxiliary functions, such as specific functions for the UMA-8.
- Get microphone positions: they are obtained from the datasheet.
- Play the movie,
- and save the movie output.
- Also it has the export script to export from .m4a to .mat which has been done in Mac, but it should "maybe" work in Linux as well. I do not know. Data was recorded using a Mac because recording is seamless and driverless using a Mac.
