Windowing input signal

Hi,
I want to window an audio signal using a Hamming window before I perform an autocorrelation on it. What are the criteria for choosing a window length.
Also, what do I do if my sequence length can not be divided up evenly by the optimum window length? i.e. do I pad the last block with zeros?

Thanks

Never pad up with Zero, well if still your input sample is not the same as what the hamming window, then Always pad it up with 1, (Technically speaking) This is not good for the Computation of energy (autocorelattion
coefficent.)
