I have been trying out FFT blocks for calculating FFT of the speech signal and again reconstructing it using FFT block in IFFT mode. I was not able to reconstruct the signal exactly.
I have been using 256 point DFT, scaled version. Also the FFT calculated using MATLAB does not yield the similar real and imaginary values as by XSG FFT block. I am attaching the simulink XSG model along with the test speech file. Plz have a look at it and comment.

plz help me on how to use ff v5 bcoz it is showing abnormal behaviour. i have tried other version that is working fine with same parameters but i have restriction to use fft v5 bcoz of cyclic prefix........
is there special treatment for fft v5?
