This version adds a few new functions such as splitting output files by length (seconds or number of words) and an option to change the volume of the output sound file on the fly. The generated files of the CGI version can now be delivered in a buffered mode, which enables sending more verbose HTTP headers (Content-Length).
Several small errors were fixed, such as the previously corrupted OGG/Vorbis headers in CGI mode, and the code was cleaned up or modularized better.
This release corrects some minor errors of version 0.8.0, such as resetting the timers after each converted chapter. New features include a function to guess the character encoding of a text file and a test mode, in which no output files are generated. New build options allow it to disable the Lame or Ogg encoders. This allows compiling ebook2cw on a system where only one of the two libraries are installed.
Support for the OGG/Vorbis audio format was added. The tone generator can now be configured to create different waveforms (sine, sawtooth, square) and a noise background can be added. There are several additional minor changes.
