title: Using pyDub to chop up a long audio file
body: <p>I'd like to use pyDub to take a long WAV file of individual words (and silence in between) as input, then strip out all the silence, and output the remaining chunks is individual WAV files. The filenames can just be sequential numbers, like 001.wav, 002.wav, 003.wav, etc.</p>
  
  <p>The "<a href="https://github.com/jiaaro/pydub/#yet-another-example" rel="noreferrer">Yet another Example?</a>" example on the Github page does something very similar, but rather than outputting separate files, it combines the silence-stripped segments back together into one file:</p>
  
  <pre><code>from pydub import AudioSegment
  from pydub.utils import db_to_float
  
  # Let's load up the audio we need...
  podcast = AudioSegment.from_mp3("podcast.mp3")
  intro = AudioSegment.from_wav("intro.wav")
  outro = AudioSegment.from_wav("outro.wav")
  
  # Let's consider anything that is 30 decibels quieter than
  # the average volume of the podcast to be silence
  average_loudness = podcast.rms
  silence_threshold = average_loudness * db_to_float(-30)
  
  # filter out the silence
  podcast_parts = (ms for ms in podcast if ms.rms &gt; silence_threshold)
  
  # combine all the chunks back together
  podcast = reduce(lambda a, b: a + b, podcast_parts)
  
  # add on the bumpers
  podcast = intro + podcast + outro
  
  # save the result
  podcast.export("podcast_processed.mp3", format="mp3")
  </code></pre>
  
  <p>Is it possible to output those podcast_parts fragments as individual WAV files?  If so, how?</p>
  
  <p>Thanks!</p>
