Hello!
I'm working on a thesis about Speech noise reduction in Matlab.

Basicly these are the steps Im following:
1.Read oiriginal signal
2.Add Gausian noise
3.Frame sampling
4.Complex Spectogram
5.Magnitude Filtering (Using a bilateral Filter)
6.Reconstruction(IFFT,Overlap resynthesized frames,Normalized resynthesized frames)

But the results are not what I expected. I wonder if somebody could suggest me something to improve it somehow (I'm trying to work with cepstral analysis but with no resuts). Maybe trying to isolate the formants from noise somehow.
I could send my code if is needed.

Thank you in advance.
