MP3 Book Helper

MP3 Book Helper is a tool created to help you quickly edit your audio file's ID3 tags.
The app comes with a clean, user-friendly interface that bundles together all the available functions in a tab-based layout.
You can load as many files as you want, either individually or as entire folders. The app then allows you to filter the tracks based on various criteria, such as name, size and duration. Furthermore, MP3 Book Helper comes with a function that enables you to find and remove duplicate files from your list.
The main feature of this software is the ability to alter the file's ID3 tags. From this tab, you can modify the name, add an author and an album name, release year and pick one of the hundreds of options for the song's genre. Also, details about the composer and copyright can be added.
Tags can be mass edited by using special variables and regular expressions. Some information can also be gathered from various online databases.
The software also allows you to generate NFO files and move the audio tracks to other folders. For the latter, you can choose a file renaming pattern and the way the words appear (all words capitalized, all upper case, all lower case, first word capitalized), as well as pick an operation for the containing folder (rename, restructure, fill sfv/par, group sfv/par).
The app supports a wide range of audio formats, such as MP3, OGG, APE, M3U, SFV, SV, PAR, SPX, AAC, FLAC and WAV.
All in all, MP3 Book Helper is a nice tool that can help you complete the information that lacks from your track's ID3 tags. Despite the advanced settings made available by this app, less experienced users should find it easy to work with this program.
