history
Project history and usage
ebook2cw is Fabian Kurz's command-line converter from plain-text ebooks to Morse-code MP3 or Ogg audio. It is niche, but historically rich inside amateur-radio tooling because it turns long-form reading material into CW practice audio.
Project history
The official changelog records the first ebook2cw release on November 22, 2007. The project page documents the current 0.8.5 release from August 16, 2023, a separate optional GUI, command-line parameters, text commands, configuration files, code tables, CGI use, and download links.
The changelog shows a classic small-tool evolution: ISO 8859-1 and UTF-8 support in 2008, configuration files in 0.7.0, Ogg output and CGI support in 0.8.0, encoding guessing in 0.8.1, gettext and more text commands in 0.8.3, and longer output filenames plus character-table fixes in 0.8.5.
Adoption history
The input metadata records packaging in Homebrew, Debian, Ubuntu, Nix, and openSUSE. That package spread is notable for a ham-radio utility because it keeps a personal-site project installable through mainstream Unix package managers.
How it is used
Typical usage feeds a text ebook to `ebook2cw`, sets CW speed, tone, bitrate, chapter splitting, output file name, and optional Ogg output, then listens to the generated practice audio. The project page also documents Project Gutenberg as a common source for public-domain ebooks.
Why package nerds care
ebook2cw is a tidy example of a domain-specific CLI that persists because packaging makes it easy to discover. It bridges ebook text, audio encoding libraries, Morse/CW learning, and ham-radio culture without becoming a broad media framework.

- 2007: Initial ebook2cw release.
