This information can be inserted by hand from the CD cover but over time large collaborative databases have been built up so once the first person has transcribed the information from a new CD and uploaded it everyone else can look it up and download it. Subsets of this data are often used to create the names of the files and folders in the structure of a music library. Most music file formats such as MP3 can and almost always have Metadata (Tags) containing information on Artist, Album Title, track Number, track Title, Genre, Year etc which is used by the music playing programs. Ripping programs often go a lot further than just extracting a series of files - they usually encode them into a compressed format such as MP3 and put them into a suitable folder structure and with suitable tags added. Ripping involves specialized software that will attempt to correct errors, and will use a variety of techniques, such as making use of error correction information, knowledge of the peculiarities of different drives, and ripping multiple times and comparing the results. This means that the data read from an audio CD may not in fact be a faithful reproduction of the original. However, CD audio's Cross-interleaved Reed-Solomon coding includes an extra facility that interpolates across uncorrectable errors. Normally, an error correction system such as Reed Solomon would provide either a perfect copy of the original error-free data, or no result at all. The CD system was designed to provide audio in real time in order to ensure continuous playback without gaps and the designers felt that it would be preferable for damage to the disc to be covered up rather than resulting in total failure. CD audio has two major design constraints that make it difficult to obtain accurate transfers to standard files. Ripping is distinct from simple file copying and in most cases the output will be split into individual compressed files corresponding to each track. Ripping means extracting audio or video content typically from a CD to a useful form on your computer. It has now been extended to include CD ripping and Music Players and Libraries Ripping CDs Introduction to Ripping This is the latest in the series and was initially created to contain my experiences in archiving all my old LP records and cassette tapes onto the computers in MP3 format in the same way as I have been transcribing all by old VHS tapes and early analogue camcorder tapes.
