title: errno 2: No such file or directory
body: <p>I've seen multiple threads with this issue but I can't find one that applies to my situation. I'm using a library called audiodiff that essentially tells you whether or not two audio files have the same content. I have recorded 2 .wav files previously saved that I want to check. Here is the code:</p>
  
  <pre><code>import audiodiff
  print audiodiff.audio_equal('output1.wav', 'output2.wav', ffmpeg_bin=None)
  </code></pre>
  
  <p>Here is the output I'm getting in the terminal when I run it:</p>
  
  <pre><code>File "/usr/local/lib/python2.7/dist-packages/audiodiff/__init__.py", line 51, in audio_equal
  return checksum(name1, ffmpeg_bin) == checksum(name2, ffmpeg_bin)
  File "/usr/local/lib/python2.7/dist-packages/audiodiff/__init__.py", line 86, in checksum
  stderr=subprocess.PIPE)
  File "/usr/lib/python2.7/subprocess.py", line 710, in __init__
  errread, errwrite)
  File "/usr/lib/python2.7/subprocess.py", line 1327, in _execute_child
  raise child_exception
  </code></pre>
  
  <p>The explanations I've seen on here have something to do with the cd, but all of my files are in the same folder. So, I'm not sure how that applies. Any insight on this would be awesome. TIA.</p>
