are always ripped from the original CD, usually with Exact Audio Copy. A recent version of LAME is always used, generally with the command-line options --alt-preset standard (which invokes variable bit rate, or VBR, encoding). The albums are then tagged as accurately as possible, in both ID3v1 and ID3v2 (note that older releases may not have ID3v2). After that, an NFO file is created, which includes a track list, album information, encoding information, release information, etc. An M3U is also created, which is a play-list file that can be used with media players such as Winamp and Windows Media Player. Finally, an SFV is created, which is a file that contains values for verifying the integrity of the files.
