title: How to normalize the volume of an audio file in python?
body: <p>I have a bunch of AAC (<code>.m4a</code>) audio files that need to be normalized, and was hoping to find a way to do it with a simple python script using some package.</p>
  <p>I found <a href="https://superuser.com/questions/323119/how-can-i-normalize-audio-using-ffmpeg">this thread</a> on superuser where someone has written an <code>ffmpeg</code> command-line utility in python, and it works well, but was wondering if there is some currently available python package with a <code>pip install</code> that would be up to the task.</p>
