Follow-up Comment #8, bug #63440 (project octave):

If you perform the same operation on the signal "normalized" BEFORE your while
loop, and with the signal amplitude reduced to +-1 (because of fct audiowrite)
by dividing "normalized" by 3 for example, you will see that the filter does
its job!

I don't know what your while loop does, but it is likely it is adding some
white noise to your signal.
I hope this helps.

By the way, why don't you use octave to plot the spectrum?
