Axone.jar is a utility allowing you to view all the information available in an MP3 file. This is not to be misunderstood: all the possible information. In the tag version 2 (ID3V2), the information is subdivided into frames and there are many more frames declared than frames actually displayed by MP3 players. Well Axone.jar knows how to display them all, without exceptions and whatever the version!

• Very classic frames such as title, album, artist, year, genre, track and comment.
• Other frames displayed by only some MP3 players.
  • the image(s).
  • the composer.
  • the text of the song.
  • volume control (itunes)
• The frames that are hidden from you (not necessarily with bad intentions).
  • private frames (MusicMatch).
  • encapsulated objects (RealJukebox).
  • abusive comments (iTunes, Mediaplayer, MusicMatch, SoundJam).
  • identification of coding software (LAME, iTunes)
  • the identification of the original CD (LAME)
  • internet links (MusicMatch)
• Undeclared frames, not understood and therefore clearly hidden from all MP3 players.
• The other frames usually not used.

Other data

The Lyrics and TAG+ tags, which are completely obsolete, may remain forgotten in certain files. If they are present, Axone.jar displays them.

When the software reads an MP3 file to display the current tag, it does a summary check of the audio data. It gives you the classic information on bitrate, sampling frequency, duration, etc.; but also if it finds excess or erroneous data. Excess data can be a sign of corrupted audio data, or of data intentionally hidden if the file was purchased on a merchant site (or if you did P2P). At this level, it is important to understand that the audio decoder is robust in the sense that data that is incomprehensible to it is simply skipped. It is therefore very easy to hide data between audio data, without risking disturbing MP3 players.
