audio signal windowing
Hi guys! I have this problem I need to sole as soon as possible.
I'm coding with matlab.
I need to filter a signal saved in a .wav file. I'm reading it using the function wavread and then I create several frames of it through Hamming window with an overlap of 50%. At this point I use fft to compute the spectrum of each frame and I make some changes on it.
At the end I want to link together all the frames (retransormed in temporal domain with ifft) and generate a wav file containing the output of the system. I don't know how to solve this last step! The problem I have is that I listen a strange noise between each frame (a noise like a clip)
Can anyone suggest me how to fix it?
