title: how can we use scipy.signal.resample to downsample the speech signal from 44100 to 8000 Hz signal?
body: <pre><code>fs, s = wav.read('wave.wav')
  </code></pre>
  
  <p>This signal has 44100 Hz sampleing frquency, I want to donwnsample this signal to 8Khz using 
  <code>scipy.signal.resample(s,s.size/5.525)</code> but the second element can't be float, so, how can we use this function for resmapling the speech signal?</p>
  
  <p>How we can use <code>scipy.signal.resample</code> to downsample the speech signal from 44100 to 8000 Hz in python?</p>
