the MS-TNEF degenerator is a Web frontend for a command line program called tnef. It accepts a "winmail.dat" file sent by Outlook users, decodes its contents, and lets the user download them. This is meant for users who keep getting Outlook attachments they can't read but don't want to use the command line.
mp3frip renames MP3 files. It features searching directories recursively, upper, lower or title case files, changing underscores to spaces and vice versa, ability to form file names from ID3v1(.1) tag (artist, song title, album, track number) if they exist and the existing file name, Test mode, Smart/Stoopid/Safer mode (won't overwrite existing files), and more.
MP3-Database is a tool to organize your MP3 collection. If you insert a CD with MP3 files in your CDROM drive, MP3DB can read all ID3 tags of the MP3 files. With this information MP3DB creates a database which can be searched for a specific song, artist, or CD. A GUI makes it easy to use the program. Any title found in the database can easily be added to a playlist or can instantly be played by XMMS.
MP3html is a utility for generating listings of MP3 files based on their ID3 tags and information such as bitrate, duration, and file size. Because it makes use of template files and is script-friendly, it can easily be used to create just about any kind of list you can think of, but its most common use is creating HTML lists for Web pages.
Mp3Make is a program that automates the ripping and encoding of CD audio to mp3 files. Since the programs commonly used in linux to do this are seperate, it made sense to make a glue program to make life easier. This is supplemented by downloading a cd track list from a cddb server, and using that to name the files being created.
