Karaoke

Karaoke (カラオケ, Karaoke? from Japanese kara, "empty" or "void", and ōkesutora, "orchestra") (pronounced IPA: /kɛɹiˈoʊki/, /kæɹiˈoʊki/, or /kəˈroʊki/; in Japanese /karaoke/; listen (help·info)) is a form of entertainment in which amateur singers sing along with recorded music using a microphone and a PA system. The music is typically a well-known pop song in which the voice of the original singer is removed or reduced in volume. Lyrics are usually displayed on a video screen, along with a moving symbol or changing color, to guide the singer. In some countries, karaoke with video lyrics display capabilities is called KTV.

History
Karaoke today was popularized by the Japanese musician Daisuke Inoue in Kobe, Japan in the early 1970s [1]. After becoming popular in Japan, karaoke spread to East and Southeast Asia during the 1980s and subsequently to other parts of the world in its modern state.
In Japan it has long been common to provide musical entertainment at a dinner or a party. Japanese drummer Daisuke Inoue was asked by frequent guests in the Utagoe Kissa, where he performed, to provide a recording of his performance so that they could sing along on a company-sponsored vacation. Realizing the potential for the market, Inoue made a tape recorder that played a song for a 100-yen coin.
Instead of selling his karaoke machines, he leased them out, so that stores did not have to buy new songs on their own. Originally it was considered a fad which was lacking the "live atmosphere" of a real performance. It was also regarded as somewhat expensive since 100 yen in the 1970s was the price of two typical lunches. However, it caught on as a popular entertainment. Karaoke machines were initially placed in restaurants or hotel rooms; soon, new businesses called karaoke boxes, with compartmented rooms, became popular. In 2004, Daisuke Inoue was awarded the tongue-in-cheek Ig Nobel Peace Prize for inventing karaoke, "thereby providing an entirely new way for people to learn to tolerate each other."
Inoue never bothered to patent his invention, losing his chance to become one of Japan's richest men. Roberto del Rosario, a Filipino inventor who called his sing-along system Minus-One, now holds the patent for the device now commonly known as the karaoke machine. Following a court battle with a Chinese company which claimed to have invented the system, del Rosario's patents were issued in 1983 and 1986, more than a decade after Inoue's original unpatented invention of the device in 1971.[2]
Early karaoke machines used cassette tapes but technological advances replaced this with CDs, VCDs, laserdiscs and, currently, DVDs. In 1992, Taito introduced the X2000 that fetched music via a dial-up telephone network. Its repertoire of music and graphics was limited, but the advantage of continuous updates and the smaller machine size saw it gradually replace traditional machines. Karaoke machines connected via fiber-optic links to provide instant high-quality music and video are becoming increasingly popular.

Karaoke soon spread to the rest of Asia and then to the United States in the 1990s. Facilities such as karaoke bars or "KTV boxes" provided the venue, equipment and software for amateur singers to entertain each other.

Karaoke has also spread to the United States, Canada and other Western countries. As the available selection of music has increased, more and more people within the industry see it as a very profitable form of lounge and nightclub entertainment. It is not uncommon for some bars to have karaoke performances seven nights a week, commonly with much more high-end sound equipment than the small, stand-alone machines noted above. Dance floors and lighting effects are also becoming common sights in karaoke bars. Lyrics are often displayed on multiple TV sets around the bar, including big screens.

Technology
A basic karaoke machine consists of a microphone, a means of altering the pitch of the recorded music, and an audio output. Some low-end machines attempt to provide vocal suppression so that one can feed regular songs into the machine and suppress the voice of the original singer, however this is rarely effective (see below). Most common machines are audio mixers with microphone input built-in with CD+G, Video CD, Laser Disc, or DVD players. CD+G players use a special track called subcode to encode the lyrics and pictures displayed on the screen, while the other formats natively display both audio and video.
Most karaoke machines have technology that electronically changes the pitch of the music so that amateur singers can sing along to any music source by choosing a key that is appropriate for their vocal range, while maintaining the original tempo of the song. (There were some very old systems that used cassettes, and these changed the pitch by altering playback speed, but none are still on the market, and their commercial use is virtually nonexistent.)
A popular game using karaoke is to randomly type in a number and call up a song, which participants take a turn to try to sing as much as they can. In some machines, this game is pre-programmed and may be limited to a genre so that they cannot call up an obscure national anthem that none of them can sing. This game has come to be called "Kamikaze Karaoke" or "Karaoke Roulette" in some parts of the United States and Canada.[citation needed]
Many low-end entertainment systems have a "karaoke mode" that attempts to remove the vocal track from regular audio CDs. This is done by center removal, which exploits the fact that in most music the vocals are in the center. This means that the voice, as part of the music, has equal volume on both stereo channels and no phase difference. To get the quasi-karaoke (mono) track, the left channel of the original audio is subtracted from the right channel.
The crudeness of this approach is reflected in the often poor performance of voice removal. Common effects are hearing the echo of the voice track (due to stereo echo being put on the vocals), and also other instruments that happen to be mixed into the center get removed (snare/bass drum, solo instruments), degrading this approach to hardly more than a gimmick in those devices.

MIDI applications and *.kar files
Some computer programs that serve a similar purpose to the standard karaoke machine have been developed that use MIDI instrumentation to generate the accompaniment rather than a recorded track. This has the advantage of making transposition technically trivial and also shrinks the information needed to provide the accompaniment to the point where it is easy to transfer it across the Internet, even over slow connections. The standard file format used is *.KAR, which is an extension of the standard .MID MIDI disk format which includes embedded lyrics and can be played unaltered by MIDI player software.

Video game
A karaoke game was initially released for the NES but its limited computing ability made for a short catalog of songs, and therefore reduced replay value. As a result, karaoke games were considered little more than collector's items until they saw release in higher-capacity DVD formats. Karaoke Revolution, created for the PlayStation 2 by Konami and released in North America in 2003, is a console game in which a single player sings along with on-screen guidance, and receives a score based on his or her pitch, timing, and rhythm. The game soon spawned four more versions, Karaoke Revolution Vol. 2, Karaoke Revolution Vol. 3, Karaoke Revolution Party Edition, and CMT Presents Karaoke Revolution: Country. While the original Karaoke Revolution was also eventually released for the Microsoft Xbox console in late 2004, the new online-enabled version included the ability to download additional song packs through the console's exclusive Xbox Live service.
A similar game, SingStar, published by Sony Computer Entertainment Europe, is particularly popular in the European and Australasian markets. Other similar titles in the rhythm-based game genre include Bemani's Dance Dance Revolution, GuitarFreaks, Donkey Konga, and DrumMania.

Karaoke VCD
The takeoff of Video CDs in East and Southeast Asia is partly due to the popularity of karaoke. Many VCD players in Southeast Asia have a built-in karaoke function. On stereo recordings, one speaker will play the music with the vocal track, and the other speaker will play the music without the vocal track. So, to sing karaoke, users play the music-only track through both speakers. In the past, there were only pop-song karaoke VCDs. Nowadays, different types of karaoke VCDs are available. Cantonese opera karaoke VCD is now a big hit among the elderly in Hong Kong.[citation needed]

Karaoke on mobile phones
In 2003, several companies started offering a karaoke service on mobile phones, using a Java MIDlet that runs with a text file containing the words and a MIDI file with the music. This is still a budding service and it is unclear whether it will become popular; however, some mobile karaoke providers, such as Karaokini, have begun to achieve commercial success.

Karaoke on computers and Internet
Starting in 2003, much software has been released for hosting karaoke shows, and playing karaoke songs on a personal computer. Instead of having to carry around hundreds of CD-G's or laserdiscs, a KJ can 'rip' their entire library onto a hard drive, and play the songs and lyrics from that.
Additionally, new software permits singers to sing and listen to one another over the Internet with collaborators/audiences from all around the world.
Various online karaoke websites provide the opportunity for karaoke enthusiasts to participate and share in a worldwide karaoke community. Users can create personal, online karaoke profiles, which store their individual recordings and even allow video syncing. Some examples of free sites are the UK-based internetkaraoke.net, Yahoo's bix.com, Electronic Arts' singshot.com and Fox Interactive's ksolo.com.
As of 2007, companies such as Sound Choice and Stellar Records are taking legal action against computer-run karaoke systems on the grounds that they violate fair use laws and that "fair use" does not apply to commercial use. They also say that format-shifting for any use is also against fair use laws.
Karaoke in automobiles
Chinese automobile maker, Geely Automobile, received much press in 2003 for being the first to equip a car, their Beauty Leopard, with a karaoke machine as standard equipment. Karaoke is often also found as a feature in aftermarket in-car DVD players.
