Ruby interface for the TagLib C++ library, for reading and writing meta-data (tags) of many audio formats.

In contrast to other libraries, this one wraps the full C++ API, not only the minimal C API. This means that all tag data can be accessed, e.g. cover art of ID3v2 or custom fields of Ogg Vorbis comments.

taglib-ruby is work in progress, but the following is already available:

  • Reading/writing common tag data of all formats that TagLib supports
  • Reading/writing ID3v1 and ID3v2 including ID3v2.4 and Unicode
  • Reading/writing Ogg Vorbis comments
  • Reading audio properties (e.g. bitrate) of the above formats

Some things are still left to do (contributors very welcome):

  • More coverage of the library

Build status

flattr this project


Before you install the gem, make sure to have taglib installed with header files (and a C++ compiler of course):

  • Debian/Ubuntu: sudo apt-get install libtag1-dev
  • Fedora/RHEL: sudo yum install taglib-devel
  • Brew: brew install taglib
  • MacPorts: sudo port install taglib

Then do:

gem install taglib-ruby


Complete API documentation can be found here:

Begin with the {TagLib} namespace.

Release Notes

See {}.


  • Check out the latest master to make sure the feature hasn't been implemented or the bug hasn't been fixed yet
  • Check out the issue tracker to make sure someone already hasn't requested it and/or contributed it
  • Fork the project
  • Start a feature/bugfix branch
  • Commit and push until you are happy with your contribution
  • Make sure to add tests for it. This is important so I don't break it in a future version unintentionally.
  • Please try not to mess with the Rakefile, version, or history. If you want to have your own version, or is otherwise necessary, that is fine, but please isolate to its own commit so I can cherry-pick around it.
