'''Gracenote''' is a company which pioneered the technology of ] recognition, and maintains and licenses a database of music and movie metadata, as well as other digital media technology and services. The database is accessible online over the Internet. ] many computer software applications that are capable of playing CDs or ] files use Gracenote's ] or similar services. These programs generally offer the option of allowing users to directly contribute information to the database. Gracenote's database was initially compiled this way, though now much of its data also comes directly from record labels and numerous other sources.


==Background== ==Background==


Gracenote began in ] as an ] project involving a CD player program named xmcd. The xmcd player was developed by ], and had the ability to store and recognize CDs from a database included with the application. xmcd users regularly sent additonal CD information to Mr. Kan for inclusion in the database via email. By 1995, the database had become unwieldy and ], a friend of Mr. Kan was recruited to build a server to store the CD information in a network database. The service quickly outgrew Scherf's ability to host and a larger server, hosting facilities, and an advertising business model was provided by an ex-pat Scot living in Texas, Graham Toal.

Because CDs do not generally contain any digitally-encoded information about their contents (see ]), Kan's software included the ability to look up CDs based on ] information stored at the beginning of each disc<ref name="WSJ" />. A TOC is a list of sector numbers, also known as ''offsets'', corresponding to the start of each track on any given CD. Because the offsets on a CD tend to be unique, they can be used for identifying CDs with a high degree of certainty. Fuzzy logic is used to heuristically compare TOCs that are similar but not exact matches, a common case for popular discs with many different batches manufactured at various times and places. The end result is a highly accurate method of identifying compact discs.

Gracenote’s pioneering work in compact disc recognition happened at just the right time to help enable the digital music revolution. The ability to recognize CDs and locate album text facilitated the easy, automatic generation of digital audio files (such as ]) in large quantities from one’s personal CD collection, a process known as ]. Without the ability to automatically name audio files, converting CDs into audio files would be a manual and onerous task. CD recognition made this possible, enabling the average user to convert personal CD collections to digital audio form without having to repurchase that same music again in a new format.


⚫ ==Commercialization and controversy==
===Evolution of Gracenote===
In ], the service was purchased by ], a high-tech venture firm and operated as a business unit within the ] based company. CDDB was then spun out of Escient in July of 2000 and renamed Gracenote (). The maneuver was and remains controversial, because the CDDB database was and is built on the voluntary submission of CD track data by thousands of individual users, who received no compensation for their work. Initially, most of these were users of the xmcd CD player program. The xmcd program itself was an open-source, ] project, and many listing contributors assumed that the database was free as well. However, at some point the code for xmcd was modified to append copyright notices to all submissions. How visible or open this was to contributors remains a matter of debate. Many contributors of track listings were angered at the transfer of these listings to a profit-making entity which proceeded to make money by charging license fees for access to a database of track listings which individuals had contributed for free.


], Gracenote claims that its database contains information on almost 4 million CDs. The reliability both of this statement and of the database itself have been challenged. Because the information going into the database has not been subjected to quality control, duplicate entries are very common. David Jennings, in an article entitled "How many CDs are there in the world?" gives an example of a six-CD set in which "two of the six CDs appear twice in the database, and one appears three times." An article on the Seattle Times website cites Ty Roberts, chief technology officer of Gracenote, as saying that there are approximately 500,000 individual CD titles commercially released and available for sale today in the United States.
Gracenote began as a CD recognition service, but has since introduced a wide variety of digital media recognition technologies and related services <ref>http://www.gracenote.com/gn_products/</ref> for the global market. The first of these was MusicID File, released in ] and based on technology purchased from Cantametrix, which offers recognition of digital audio files such as MP3s and other popular file formats. In ] Gracenote purchased audio recognition technology from ] that is highly tolerant of noise and allows for the recognition of music over a cell phone microphone. This service was rolled out as Mobile MusicID. Gracenote technology is used in music and video players, PC software, home consumer electronics products, mobile music applications, cell phone handsets, and automobile audio and navigation systems. Gracenote products are used by millions of consumers worldwide. In ] Gracenote announced <ref>http://gracenote.com/corporate/press/article.html/date=2006071700</ref> that it had signed agreements licensing lyrics rights from many of the world’s leading music publishers, for the first time enabling the legal use of song lyrics in consumer electronic devices, PC applications and web services.

The move was controversial to some, because the CDDB database was built on the voluntary submission of CD track data provided by individual users. Initially, most of these were users of the xmcd CD player program. The xmcd program and CDDB server software were open-source, ] projects, and many contributors assumed that the database was as well.

For grace notes in music, see grace note.

Gracenote is a commercial enterprise which maintains and licenses a database containing information about the contents of audio CDs. The database is accessible online over the Internet. As of 2005 many computer software applications that are capable of playing CDs use Gracenote's CDDB or similar commercial services such as All Media Guide's AMG LASSO and MusicIP, or open-source projects such as freedb and MusicBrainz. These programs generally offer the option of contributing track listings, and most of the track listings in the Gracenote database are voluntary contributions by individual users of CD-player software.

Background

Gracenote began in 1993 as an open source project involving a CD player program named xmcd. The xmcd player was developed by Ti Kan, and had the ability to store and recognize CDs from a database included with the application. xmcd users regularly sent additonal CD information to Mr. Kan for inclusion in the database via email. By 1995, the database had become unwieldy and Steve Scherf, a friend of Mr. Kan was recruited to build a server to store the CD information in a network database. The service quickly outgrew Scherf's ability to host and a larger server, hosting facilities, and an advertising business model was provided by an ex-pat Scot living in Texas, Graham Toal.

CDs do not generally contain any digitally-encoded information about their contents (see CD-Text), Kan developed software which identifies and looks up CDs based on TOC information stored at the beginning of each disc. A TOC, or Table of Contents, is a list of offsets corresponding to the start of each track on a CD. The matching is fuzzy and tolerates some variation in track offsets.

Some computer users who have copied vinyl LPs from their turntables onto CD-Rs have been astonished to find their computers correctly displaying the titles and track listings when these CD-Rs are played on their computer. This happens when a commercial CD is a remastered version of an LP, containing the same tracks in the same order. If the track offsets of the homemade CD match the track timings of the commercial CD to within a second, the CDDB database can identify the CD successfully.

Commercialization and controversy

In 1998, the service was purchased by Escient, a high-tech venture firm and operated as a business unit within the Indiana based company. CDDB was then spun out of Escient in July of 2000 and renamed Gracenote (press release). The maneuver was and remains controversial, because the CDDB database was and is built on the voluntary submission of CD track data by thousands of individual users, who received no compensation for their work. Initially, most of these were users of the xmcd CD player program. The xmcd program itself was an open-source, GPL project, and many listing contributors assumed that the database was free as well. However, at some point the code for xmcd was modified to append copyright notices to all submissions. How visible or open this was to contributors remains a matter of debate. Many contributors of track listings were angered at the transfer of these listings to a profit-making entity which proceeded to make money by charging license fees for access to a database of track listings which individuals had contributed for free.

As of 2005, Gracenote claims that its database contains information on almost 4 million CDs. The reliability both of this statement and of the database itself have been challenged. Because the information going into the database has not been subjected to quality control, duplicate entries are very common. David Jennings, in an article entitled "How many CDs are there in the world?" gives an example of a six-CD set in which "two of the six CDs appear twice in the database, and one appears three times." An article on the Seattle Times website cites Ty Roberts, chief technology officer of Gracenote, as saying that there are approximately 500,000 individual CD titles commercially released and available for sale today in the United States.

Lawsuits

The commercialization of CDDB by Gracenote also caused friction with its former licensees. In 2000, Gracenote sued Roxio for breach of contract when Roxio tried to switch to freedb. The case was settled in 2001.

Gracenote v. Musicmatch

In 2002, Gracenote sued another former licensee, Musicmatch, for breach of contract and patent violations. Musicmatch filed a counter-suit against Gracenote. The Northern District Court in California ruled on August 26, 2004 in favor of Musicmatch. The case was settled in 2004 after Musicmatch received summary judgement on all of Gracenote's patent claims.

A summary judgement found that Musicmatch's CDDB replacement service does not violate Gracenote's patents. The court also found significant evidence that Gracenote may have obtained its patents fraudulently. The court order is available online. A summarized overview of the case is available at the Manatt website within Mr. Robert D. Becker's list of representative cases. Mr. Becker was one of Musicmatch's lawyers during the case.

Gracenote's loss in the Musicmatch case has opened the market for competition, and a growing group of companies continue to enter media identification and metadata marketplace.

Competition

Many of Gracenote's small former licensees moved to non-commercial services such as freedb because of restrictive terms and anger over the privatization of the company. Several large commercial licensees dropped Gracenote's service, such as Microsoft's Windows Media Player and Musicmatch Jukebox, and have moved to the commercial service provided by All Media Guide.

The AMG LASSO media recognition service was launched in late 2004 by All Media Guide. The service allows for the recognition of DVDs and digital audio files such as MP3s, as well as CD recognition, and directly competes with Gracenote in the software and embedded device markets globally.

MusicBrainz is also another music identification service that is open source and created by community contributions.
