Check MP3 files for errors with MP3 Diags

MP3 Diags is a free application that will allow you to identify issues with your MP3 files, fix some of them and make other changes, like adding track information. It also lets you “look inside” an MP3 file. Unlike some programs that are designed to deal with a single issue (like fixing VBR headers or adding cover art), MP3 Diags is an one stop solution that identifies more than 50 possible problems in MP3 files and provides the means to fix them.

Some of the most important issues that are found: broken tags / headers / audio * duplicate tags / headers * incorrect placement of tags / headers (ID3V2, ID3V1, LAME, Xing, …) * low quality audio * missing VBR header * missing track info / cover art * broken track info / cover art * missing normalization data * character encoding issues (for languages other than English).

Some of the fixes and changes that MP3 Diags can do: Adding / fixing track info, including album cover; information can be retrieved from several sources: Internet, clipboard, file name, local files, and (obviously) keyboard * Correcting files that show incorrect song duration * Correcting files which the player cannot seek right * Converting characters for non-English names * Adding composer name to the artist field, for players that don’t handle the composer field * Renaming files based on their fields * Changing word case for track info

Intended target: this program is not really meant for those who want to push a button and have everything fixed automatically, but rather for people who have some technical background. Automatic tagging is neither implemented nor planned. If you want to use those parts of MP3 Diags functionality that alter existing files, it is highly advisable to back up your files first, because there is a real chance of data loss. It can be caused by both user error and bugs in the program.
