hello xaq
the 2 sets of data are the results from using the Cepstrum algorithm to estimate the pitch period of a signal in 2 different occasions.my signal is the same for both cases.what changes is the length of the segments of the signal (cepstrum is a block based algorithm. you have to segment the signal in order to use it).in the first case the length of each segment is 384 samples long and 320 for the other case.
what i want to do is this, i want to check and make sure that both these cases are correct and get the same results.i ma thinking that the pitch periods should be at the same spot no matter what the segment index should be.
for example lets say the first pitch (actually a peak in the signal) is at the t=0.5 seconds. in the first case it should be shown in segment 10 for example while in the other case it should be in segment 12 for example (since segments length is not the same).i just want to check if the timing of these peaks occur at the same time index in both cases.thats why i want to normalize them.
i dont know if i confused you even more.thank you though for your time and effort
