Feature Chains

Our AR feature chain consisted of:

   [y, jout] = module_dftmsq(x, 0);
   [r,jout] = module_ar_ml(y, jout, P);
   [k,jout] = module_acf2rc(r, jout);
   [z, jout] = module_bilinear(k, jout);

Our MFCC feature chain consisted of:

   fs=16000; lin=0; type=0; % set MEL band spacing and shape
   [y, jout] = module_dftmsq(x, 0);
   [w,jout] = module_mel_ml(y,jout,Nc,type,fs,0);
   [z,jout] = module_log(w, jout, [1:Nc]);
   z=dct(z);

or:

   fs=16000; type=0; % set MEL band spacing and shape
   [y, jout] = module_dftmsq(x, 0);
   [w,jout] = module_mel_bank(y,jout,Nc,'spa',type,fs);
   [z,jout] = module_log(w, jout, [1:Nc]);
   z=dct(z);
