Kid3 is an open source Qt-based application to edit the ID3v1 and ID3v2 tags in MP3 files in an efficient way. These tags can be edited by most MP3 players, but not in a very comfortable way. Tags in Ogg/Vorbis, FLAC, MPC, MP4/AAC, MP2, Speex, TrueAudio and WavPack files are supported too.
Where most other programs can edit either ID3v1 or ID3v2 tags, Kid3 has full control over both versions, can convert tags between the two formats and has access to all ID3v2 tags.
The tag information for full albums can be taken from gnudb.org, TrackType.org, MusicBrainz, Discogs, Amazon or other sources of track lists. The import format is freely configurable by regular expressions.
kid3-cli provides a command-line-interface for Kid3.
Please note, Kid3 does not grab, encode nor play MP3 files.
