Florian Heidenreich and the Mp3tag project
Mp3tag is developed by Florian Heidenreich, who runs the project site at mp3tag.de. The package ID is FlorianHeidenreich.Mp3tag, and the app sits in the utilities category with tags for audio, ID3, MP3, music and tag.
The license is Freeware and the app is free.
Batch editing across ID3, MP4, WMA, Vorbis and APE tags
The core job is editing metadata for many files at once. Mp3tag handles ID3v1, ID3v2.3, ID3v2.4, iTunes MP4, WMA, Vorbis Comments and APE Tags, which covers several audio formats in a single library.
It can also look up tags online from sources such as Discogs, MusicBrainz or freedb, and download cover art that way. Beyond tagging, you can rename files from their tag data, replace characters or words in tags and filenames, import and export tag information, and create playlists.
Requirements and compatibility on Windows
Mp3tag targets Windows. Check the developer site at mp3tag.de/en before installing on an older system. The package size is 5.7 MB.
What's new in 3.36.1
Version 3.36.1 fixes a regression in which a deadlock occurred when adding cover art to files that already had different covers. The problem had been present since v3.36-beta.5.
