I am writing a code to plot a real time mic recorded audio. I am able to plot the fft. I also want to plot a small portion of that fft say milli secs of that fft. can someone help with this? thanks. 댓글 수: 1 mohanish2018년 9월 17일 ...
I am trying to understand basic fft functions of a shifted time series and my graphs are not appearing as I expect them to:To plot the FFT of a shifted time series and understand its behavior, it is important to ensure that the time and frequency domains are correctly handled. The curr...

depending on your research goals, consider analyzing frequency domain features using techniques like Fast Fourier Transform (FFT) or investigating muscle co-activation patterns during propulsion. If you still require further assistance or specific code implementations for additional analyses, feel free ...
