What is MP3 Diags?
MP3 Diags helps you investigate an MP3 collection before deciding what to change. Its main window lists files alongside diagnostic notes and exposes the tags, headers and audio streams inside a selected file. It can identify issues such as duplicate tags, missing VBR headers, incorrect duration information and missing cover art.
For files that need attention, you can apply specific transformations, edit track information and album images, or rename files using their tags. It is intended for people willing to inspect technical details, rather than a single-button repair workflow. The linked download is the publisher's stable-branch 1.4.01 Windows installer, not the separately listed unstable branch.
Back up your music before making changes: the publisher explicitly warns that mistakes or program bugs can cause data loss. Repairs cannot restore audio detail lost in a low-bitrate recording, and automatic tagging is not implemented. The documentation also says MusicBrainz and Discogs integration is disabled; do not choose this version expecting online album lookup.
