Hello,
I have also made a project with overlap add method regarding wiener filtering.
Now, the problem with Hann window (actually with any window other than
rectangular) is that it isn't constant. So Just by windowing your signal
you have done some distortion. So overlap add method would be advisable.
On the mathworks homepage (matlab) there are a lot of overlap-add examples in
diffrent applications.
I would advise you to start with a 50% overlap, this is standard. And then you
can decrease it is you application permits that.
Hope this was of any use

the spectral data, my guess is because I'm not doing any overlap. Would
this be a spot where the overlap add method is used? If so, how much overlap
would be needed?
