title: signal processing for audio file in python
body: <p>I am tying to do silence detection in uncompressed AIFF audio files. I prefer to do it in Python, but would consider other options if this is super inefficient. The uncompressed files I am dealing with are expected to be 20 MB (maximum size). </p>
  
  <p>I can understand basics of signal processing, but am not an expert in it. </p>
