AudioGrail is a tool to manage and rename your MP3 files. You can rename files based on FreeDB album information and automatically apply ID3 tags (v1 and v2). In addition, you can create export lists of your audio files, perform bulk file name cleanups (convert spaces, capitalize etc.), create playlists and more. AudioGrail supports mp3, ogg, vqf, wma, wav, mpc and ape formats. The trial version does not expire, but is limited to process 30 files simultaneously.
