Splits Audiobook mp3 files into chapters

MP3 Chapter Splitter

This utility reads the headers of MP3 audiobook files and splits them according to the information found in the tags. For each original file, it will create a new directory and then create a numbered sequence of files each with a section of the original file. It requires the ffmpeg command line utility to split the files

It is currently written to split files that are downloaded from the Overdrive service from our library. These files store the chapter markers in the UserTextFrames MP3 header. The markers are stored in an xml format:

<Markers>
   <Marker>
      <Name>Episode 5</Name>
      <Time>00:00.000</Time>
   </Marker>
   <Marker>
      <Name>      Episode 5 (03:42)</Name>
      <Time>03:42.227</Time>

The project is currently in the "userful tool for me" stage and has not been tested beyond seeing that it works on the files I needed splitting.

If you're interested in more features or have a file it doesn't work with, send me a note or create an issue and I'll see what I can do!
