Technically, it is possible that all digital music pieces have stored meaningful additional information. This makes it possible for your MP3 player, for example, to display the artist or the album.
But if an information is missing, it is a Sisyphus task to incorporate the individual tags later. Kid3 does this job extremely comfortably and gets along with both ID3v1 and ID3v2. Audio formats support MP3, Ogg / Vorbis, MP4 / AAC, WMA, WAV and others.
The Kid3 user interface is divided into five sections: the file list box and the directory list box are on the left, the right side contains the file names, Day 1 and Day 2 sections. So it is possible, for example, to take over the information from tags or to get tags from the file name.
