title: How do I compare and visualise two .wav files in Python 3?
body: <p>I am using Python 3 on Jupyter and I am trying to find out the accuracy of an audio file (has some noise) with the original one which has none. Please find the code, that I found online, below,</p>
  
  <pre><code>import librosa
  import matplotlib.pyplot as plt
  from dtw import dtw
  
  #Loading audio files
  y1, sr1 = librosa.load('data/dev1_female3_liverec_130ms_1m_sim_1.wav') 
  y2, sr2 = librosa.load('data/dev1_female3_liverec_130ms_1m_sim_1o.wav') 
  
  #Showing multiple plots using subplot
  plt.subplot(1, 2, 1) 
  mfcc1 = librosa.feature.mfcc(y1,sr1)   #Computing MFCC values
  librosa.display.specshow(mfcc1)
  
  plt.subplot(1, 2, 2)
  mfcc2 = librosa.feature.mfcc(y2, sr2)
  librosa.display.specshow(mfcc2)
  
  dist, cost, path = dtw(mfcc1.T, mfcc2.T)
  print("The normalized distance between the two : ",dist)   # 0 for similar audios 
  
  plt.imshow(cost.T, origin='lower', cmap=plt.get_cmap('gray'), interpolation='nearest')
  plt.plot(path[0], path[1], 'w')   #creating plot for DTW
  
  plt.show()
  
  </code></pre>
