Audibook convert m4b to mp3. This will split into chaptered mp3 files and automatically reconfigure proper ID3v2 tags.
#!/bin/bash
#
# sudo apt-get install id3v2 ffmpeg
#
# USAGE:
# cd /book title/
# bash ~/this_script_path.sh
# rm *.m4b (you need to manually remove the original in case something goes wrong)
