title: Sliding DFT vs. single DFT but bigger
body: <p><strong>Context:</strong> formant extraction using cepstrum analysis.</p>
  <p>When analysing frequencies in streaming input from the microphone, is there any advantage of using a sliding DFT with a small frame size (say 512) vs. using a bigger, non-sliding DFT (say 16384) in terms of accuracy?</p>
