What is the Hamming window for?

Question

I\'m working with some code that does a Fourier transform (to calculate the cepstrum of an audio sample). Before it computes the Fourier transform, it applies a Hamming window t

Answer 1

With what I know about sound and quick research, it appears that Hamming Window is here to minimize the signal side lobe (unwanted radiation). Thus improving the quality or harmonics of the sound. I also understand this type of window function fits good with DTFT.

You will find some good technical explanation on a stanford researcher page or wikipedia and also in a paper of Harris if you are ready for maths :D.
