What is Tag? 

Tag is a metadata editor for FLAC, Ogg Vorbis, Monkey's Audio and WavPack files.

Tag has an intuitive interface that simplifies common editing tasks while also allowing direct manipulation of tags. Tags can be dragged between files, or Tag can even add all the tags contained in one file to another in one fell swoop.

For files with incomplete or missing metadata, Tag can guess tag values by matching the filename to a user-defined pattern. Alternatively, Tag can rename files by substituting tag values into a user-defined pattern.

Need to make many parallel changes? No problem! Tag can edit multiple files simultaneously, eliminating repetition and saving time.

For advanced users Tag features customizable mappings that allow you to specify which tags are mapped to the various fields in the user interface.

Tag is free software released under the GNU General Public License (GPL).

Building Tag from source requires the Xcode 3.1 tools from Apple, as well as the following packages compiled as frameworks:

If you would rather not compile these from source, you may download a zip file containing precompiled versions of the frameworks here (783 KB). Unzip this archive into Tag's source directory.

The Tag source code repository is available for public access. To check out the source code anonymously, issue the following command in Terminal:

git clone git:// Tag

You will also need to download the frameworks as described above, as they are not checked into the repository.
