Metatogger is a tag editor for Ogg Vorbis, FLAC, Opus, M4A (AAC and ALAC) and WMA audio files.

A tag is a metadata, i.e. data about data. A tag provides additional information related to the audio data itself: the author of the lyrics, the composer of the music, the name of the album from which the song was released, the release date, etc. These tags or metadata make it possible to exploit large music collections more pleasantly.

The problem is that many audio files contain no metadata at all, while others contain erroneous, unnecessary or inconsistent informations. Sometimes even the file name does not contain any relevant information. It is difficult, under these conditions, to identify a song without having to play it. This is where Metatogger comes in.

Metatogger allows you to correct or complete the tags of audio files. To do so, it has features that allow to correct or complete the tags of audio files:

  • to edit the tags en masse, with support for multiple tags (a single tag with several values) and tags containing line feeds;
  • to automate all types of processing using C# scripts: replace characters, change tag case, etc.;
  • to get tags from the file name or path;
  • to rename, copy (physically or symbolically) or move audio files according to the value of their tags;
  • to classify the audio files in folders according to the value of their tags (copy, move, symbolic link);
  • to search for the audio files to be tagged in a local database containing 2.5 million discs, whose data is taken from the online encyclopedia MusicBrainz, to automatically extract the information, including track numbers;
  • to search for disc covers on, then add them as tags or copy them to the folder where the audio file is stored;
  • to automatically find the name of the artist and the title of the song after analyzing its acoustic fingerprint, using Acoustid technology;
  • to identify potentially duplicated audio files, even if they are not strictly identical (encoding parameters, file format, etc.), using Acoustid acoustic fingerprint recognition technology;
  • to quickly remove undesirable tags.

What the specialized press says about it

Metatogger offers fast and easy tagging of large music collections, a high degree of customizability, an attractive and efficient interface, and lots of convenience, including automatic updates. It shows just how far MP3 tag editors have come since the Napster era.

Après avoir testé un grand nombre d'applications diverses et variées en vue de renommer et ajouter des informations à mes fichiers MP3, aucune ne m'avait véritablement convaincu jusqu'à ce que j'installe Metatogger. Le point fort de ce logiciel (en plus d'être gratuit) étant qu'il fait vraiment tout tout seul… et qu'il le fait bien…

No overkill of tabs, windows, hundreds of options, slow tagging, large size. Metatogger is a solution for everyone. […] Behind its sober interface, has the most powerful features to customize as far as you want your music library. Adding your own tags is a breeze, organizing a huge library with personalized patterns, and even small scripts is not a problem, as little as sorting all the files you want to tag according to every possible criteria. The only limit for the advanced user is your own imagination. There are many other things to be said […], making the software faster, smaller, and more ergonomic than its competitors.
Softpedia Team,

The good thing about Metatogger is that you can instantly preview any changes done to the file's tags and then decide if you want to keep those changes or you'd rather discard them. Metatogger features a very attractive interface with a nice design.
