Next if the length of … Web6 jan. 2024 · Let's say you choose a window length of 1000 and a hop size of 1 (i.e. overlap of 999). Technically you have a time resolution of 1 but let's see what happens if we analyze a unit step: Before the unit step the spectrogram is all zeros and the final state is that the spectrogram being all ones. However, the transition will be quite slow.

Web13 okt. 2024 · I can move it to the GPU by creating the window as a tensor. window = torch.hamming_window (window_length = window_len, device = "cuda") But then the problem is that the Spectrogram function only seems to accept the window as a function and not a tensor, at least from my testing/understanding. Here’s a reproducible example, … Web8 feb. 2024 · It seems like @Robert_Crovella might have an idea already, because I just saw, that he replied on that very stackexchange question.
