gen_chroma.m: function code for generating chroma from the wave file (called by other modules)
Input: name of the wave file
Output: chroma information in the memory
Compare_ChormaMat.m: code for computing chroma comparison matrix from two wave files.
Input: selecting two wave files.
Output: matrix figure and matlab .mat file
compare_DP.m: code for running dynamic programming algorithm on the chroma comparison matrix.
Input: matlab .mat file that stores the chroma comparison matrix (generated by Compare_ChromaMat.m)
Output: matrix figure along with the optimal path found by DP.
