ica_f.m bsepf2 is the main program and it needs correlation.m decorrelation.m permutation.m sepfilter.m. You also need to visit ftp://sig.enst.fr/pub/jfc/Algo/Joint_Diag/ and get a matlab code "joint_diag.m". this is by Jean-Fran\c{c}ois Cardoso. You have to put the code under this directory "ica". usage is function [Y1,Y2] = ica_f(X,NFFT,FS,OVERLAP,N) where X : is a ".wav" data (You should use 16kHz sampling rate). NFFT : number of the FFT points. FS : sampling rate (it should be 16000 Again..) OVERLAP : overlap of the window function, if sampling rate 16kHz, it should be NFFT-20. N : number of the matrixes to be simultaneous diagonalized. 40 is my recommendation. I use this ica_f in the following way. >> X=wavread('***.wav') >> [Y1,Y2] = ica_f(X,512,16000,492,40); X_linear.wav, X_room.wav are for test use. X_linear is an instantaneous mixture, and X_room is a convolutive mixture. Shiro Ikeda, shiro@ikeda.cc
