Cue sheets are stored as plain text files and commonly have a .cue filename extension.
CDRWIN first introduced cue sheets,[1] which are now supported by many optical disc authoring applications and media players.
However, the TRACK command in a cue sheet file can be used to refer to binary disc images that contain only the user data of each sector, by indicating the specific CD mode of the tracks from which the image was created (which is necessary to know the size of the user data in each sector).
[1] The specification for that command defines a cue sheet format containing mostly the same information, but in a tabular, binary data structure, rather than a text file.
[2] In October 2023, a vulnerability was discovered in the libcue library, which parses cue sheets on Linux systems with GNOME desktops.
The original specification of the cue sheet syntax and semantics appears in the CDRWIN User Guide.
A number of programs, including VLC and Foobar2000, allow the use of WavPack and FLAC files before a WAVE filetype.
Therefore, the track listing is as follows: Since the MP3 is one file containing the entire performance, burning it to a CD as-is would make it inconvenient to skip to individual songs.
