This script allows changing the reading pace of audiobooks. It does so by lengthening or shortening pauses the reader takes between sentences / paragraphs.
The following command lengthens all pauses longer than 0.6 seconds by 25%. Use ./audiobookpacer.rb -h for all options.
./audiobookpacer.rb --length 0.6 --ratio 1.25 input.wav output.wav
These default values are suitable for making The Hunger Games audiobook more enjoyable.
Since the program cannot read/write MP3's natively, there's a separate script that converts an entire directory of MP3 files:
./convert-mp3.sh input_dir/ output_dir/ --length 0.6 --ratio 1.25
For the main script:
- Ruby
- libsndfile development files
sudo apt-get install libsndfile1-dev
- ruby-audio gem
gem install ruby-audio
For the MP3 conversion script:
- mpg123
- lame
- id3cp
sudo apt-get install mpg123 lame libid3-tools
