ebook2cw

ebook2cw is a command line program that converts a plain text file (like an eBook) to Morse code (CW) MP3 or OGG files. Morse parameters like speed and tone frequency, and audio parameters such as bit rate, sample rate, and quality can be changed by command line switches. It automatically splits and numbers the output files by chapters.

Release Notes: 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.

Release Notes: 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.

Release Notes: 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.

  •  03 Jul 2008 17:20

Release Notes: This version allows the user to define arbitrary character mappings, in order to deal with any symbols that have no common equivalent Morse symbol, without the need to modify the input data. A set of default parameters can now be read from a configuration file.

  •  20 May 2008 14:35

Release Notes: Different possibilities were added to achieve Farnsworth-like spacing, with increased inter letter and/or inter word spacing. Automatic reset of the speed increase by every new chapter can now be disabled.
