I have already set up the windowing function, which is hann(128), but I have no idea how to use it to caputer a time slide in my test.wav, let say I would like to capture at time 4s in my test.wav.
So my question is how to move this hann(128) to center at 4s of my test.wav, and also how to multiply them? as I got error saying something like wrong dimension.
Thank you very much in advance
