Editing Compact Disc Digital Audio (section)

== Standard ==
The ''Red Book'' specifies the physical parameters and properties of the CD, the optical parameters, deviations and error rate, modulation system ([[eight-to-fourteen modulation]], EFM) and error correction facility (CIRC), and the eight [[Compact disc subcode|subcode channels]]. These parameters are common to all compact discs and used by all logical formats: audio CD, [[CD-ROM]], etc. The standard also specifies the form of [[digital audio]] encoding.

The first edition of the ''Red Book'' was released in 1980 by Philips and Sony;<ref name="BBC" /><ref name="Auto45-1" /> it was adopted by the Digital Audio Disc Committee and ratified by the [[International Electrotechnical Commission]] (IEC) Technical Committee 100 as an [[international standard]] in 1987 with the reference IEC 60908.<ref name="Auto45-2" /> The second edition of IEC 60908 was published in 1999<ref name="Auto45-3" /> and it replaces the first edition, amendment 1 (1992) and the corrigendum to amendment 1. The IEC 60908 however does not contain all the information for extensions that is available in the ''Red Book'', such as the details for [[CD-Text]], [[CD+G]] and [[CD+EG]].<ref>{{Cite web|url=https://www.edocpublish.com/resources-2/specifications/cd-logos/|title=CD Logos|website=Edocpublish.com|date=4 February 2013|access-date=21 January 2023|archive-date=8 July 2018|archive-url=https://web.archive.org/web/20180708044901/https://www.edocpublish.com/resources-2/specifications/cd-logos/|url-status=live}}</ref><ref>{{Cite web|url=https://www.ccs.neu.edu/home/bchafy/cdb/info/info.html|archive-url=https://web.archive.org/web/20120501075730/https://www.ccs.neu.edu/home/bchafy/cdb/info/info.html|url-status=dead|title=Specs for Freeware Developers|archive-date=1 May 2012}}</ref>
