title: MFCC feature extraction, Librosa
body: <p>I want to extract mfcc features of an audio file sampled at 8000 Hz with the frame size of 20 ms and of 10 ms overlap. What must be the parameters for librosa.feature.mfcc() function. Does the code written below specify 20ms chunks with 10ms overlap?</p>
  
  <pre><code>import librosa as l
  
  x, sr = l.load('/home/user/Data/Audio/Tracks/Dev/FS_P01_dev_001.wav', sr = 8000)
  mfccs = l.feature.mfcc(x, sr=sr, n_mfcc = 24, hop_length = 160)
  </code></pre>
  
  <p>The audio file is of 1800 seconds. Does that mean I would get 24 mfccs for all (1800/0.01)-1 chunks of the audio?</p>
