Parallel SRP-PHAT for GPUs

Simple Demonstration on Simulated Data.

Execution

On Windows and MATLAB, (the codes were tested on Windows7 64-bit and MATLAB2009b).

1. Download LDC93S1.wav file from here. Copy the file into 1_gen_simul_data folder.
2. Execute ./1_gen_simul_data/main.m.
3. Execute ./2_data_preprocessing/main.m.
4. Execute ./3_gen_TDOA_tables/frequency_domain/main.m.
5. Execute ./3_gen_TDOA_tables/time_domain/main.m.

On Linux which is installed CUDA, (the codes were tested on CUDA 7.0, GTX TITAN X, Ubuntu 14.04.02 64-bit).

1. Execute ./4_parallel_srp-phat/run.sh on a terminal. (Please make sure that the execution permissions of *.sh files are set correctly. If not, you may set the permission with chmod 777 *.sh command).

Experiment result log files are saved in ./4_parallel_srp-phat/exp_total/result/log. For more detailed explanation, please refer to the paper below.
