GabTag

GabTag is an audio tagging tool for Linux. It operates on the metadata carried inside audio files — the descriptive fields that music players read to build their libraries, such as title, artist, album and track information — rather than on the audio stream itself. In other words, it belongs to the file-organisation side of a music collection rather than to recording, editing or format conversion.

The program is published by Ismaïl Lachheb and distributed under the GPL-3.0-or-later license, meaning the source code may be studied, modified and redistributed under the same terms. Its packaging is listed for Linux only, so anyone working primarily on Windows or macOS would need to look elsewhere for an equivalent.

The details beyond that stated purpose — which container and codec formats are handled, whether tags can be edited in batches, and whether any online metadata lookup is involved — are not covered by the facts recorded here and should be confirmed against the project's own documentation before relying on them.
