In the file of SubbandAnalysis.cxx, the function of SubbandAnalysis::Init() 

Now there are 8 subbands, the formula is :
             _Mr(i,k) = cos((2*i + 1)*(k-4)*(M_PI/16.0));
             _Mi(i,k) = sin((2*i + 1)*(k-4)*(M_PI/16.0));

if increase subbands to 16, does formula change to :
            _Mr(i,k) = cos((2*i + 1)*(k-8)*(M_PI/32.0));
            _Mi(i,k) = sin((2*i + 1)*(k-8)*(M_PI/32.0));
