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 R
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 speakin= g) This is not good for the Computation of energy (autocorelattion coefficent.)
