taglib-ruby

Website: http://robinst.github.com/taglib-ruby/

Ruby interface for the TagLib C++ library.

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
