title: Sound feature attributeError: 'rmse'
body: <p>In using librosa.feature.rmse for sound feature extraction, I have the following:</p>
  <pre><code>import librosa
  import numpy as np 
  
  wav_file = &quot;C://TEM//tem//CantinaBand3.wav&quot;
  y, sr = librosa.load(wav_file)
  
  chroma_stft = librosa.feature.chroma_stft(y=y, sr=sr)
  
  rmse=librosa.feature.rmse(y=y)[0]
  
  print rmse
  </code></pre>
  <p>It gives me:</p>
  <pre><code>AttributeError: 'module' object has no attribute 'rmse'
  </code></pre>
  <p>What's the right way to get it?</p>
