Finally, we took the machines with wireless and Bluetooth capabilities outside and measured the range of their signals. We also assessed the general speaker quality at different volumes. After that, we opened up and disassembled each of the units to get a better look at their individual components and how well they were wired together.
Karaoke (/ˌkæriˈoʊki/; Japanese: [kaɾaoke] (listen); カラオケ, clipped compound of Japanese kara 空 \"empty\" and ōkesutora オーケストラ \"orchestra\") is a type of interactive entertainment usually offered in clubs and bars, where people sing along to recorded music using a microphone. The music is an instrumental version of a well-known popular song. Lyrics are typically displayed on a video screen, along with a moving symbol, changing colour, or music video images, to guide the singer. In Chinese-speaking countries and regions such as mainland China, Hong Kong, Taiwan and Singapore, a karaoke box is called a KTV. The global karaoke market has been estimated to be worth nearly $10 billion.
From 1961 to 1966, the American TV network NBC carried a karaoke-like series, Sing Along with Mitch, featuring host Mitch Miller and a chorus, which superimposed the lyrics to their songs near the bottom of the TV screen for home audience participation. The primary difference between Karaoke and sing-along songs is the absence of the lead vocalist.
The patent holder of the karaoke machine is Roberto del Rosario, who is from the Philippines. He developed the karaoke's sing-along system in 1975 and is recognized as the sole holder of a patent for a karaoke system in the world.
In 1992, a scientist named Yuichi Yasutomo created a networked karaoke system for Brother Industries. Called \"tsushin karaoke\" (\"communications karaoke\") it served up songs in MIDI format via phone lines to modem-equipped karaoke machines. This new technology swept Japan; by 1998, 94% of karaoke was being sung on networked karaoke machines. As an early form of music on demand, it could be called the first successful audio streaming service. It also allowed for big data analysis of songs popularity in realtime.
Karaoke soon spread to the rest of Asia and other countries all over the world. In-home karaoke machines soon followed but lacked success in the American and Canadian markets. When creators became aware of this problem, karaoke machines were no longer being sold strictly for the purpose of karaoke but as home theater systems to enhance television watching to \"movie theater like quality\". Home theater systems took off, and karaoke went from being the main purpose of the stereo system to a side feature.
As more music became available for karaoke machines, more people within the industry saw karaoke as a profitable form of lounge and nightclub entertainment. It is not uncommon for some bars to have karaoke performances seven nights a week. commonly with high-end sound equipment superior to the small, stand-alone consumer versions. Dance floors and lighting effects are also becoming common sights in karaoke bars. Lyrics are often displayed on multiple television screens around the bar.
A basic karaoke machine consists of a music player, microphone inputs, a means of altering the pitch of the played 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 remove the voice of the original singer; however this was, historically, rarely effective. Most common machines are CD+G, Laser Disc, VCD or DVD players with microphone inputs and an audio mixer built in. CD+G players use a special track called subcode to encode the lyrics and pictures displayed on the screen while 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 choose a key that is appropriate for their vocal range, while maintaining the original tempo of the song. (Old systems which used cassettes 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 type in a random number and call up a song, which participants attempt to sing. 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 the participants can sing. This game has come to be called \"Kamikaze Karaoke\" or \"Karaoke Roulette\" in some parts of the United States and Canada.
Many low-end entertainment systems have a karaoke mode that attempts to remove the vocal track from regular audio CDs, using an Out Of Phase Stereo (OOPS) technique. This is done by center channel extraction, which exploits the fact that in most stereo recordings 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 Sega Saturn also has a \"mute vocals\" feature that is based on the same principle and is also able to adjust the pitch of the song to match the singer's vocal range.
Early karaoke machines used 8-track cartridges (The Singing Machine) and cassette tapes, with printed lyric sheets, but technological advances replaced this with CDs, VCDs, laserdiscs and, currently, DVDs. In the late 1980s and 1990s, Pioneer Electronics dominated the international karaoke music video market, producing high quality karaoke music videos (inspired by the music videos such as those on MTV).
In 1992, Taito introduced the X2000, which fetched music via a dial-up telephone network. Its repertoire of music and graphics was limited, but its smaller size and the advantage of continuous updates saw it gradually replace traditional machines. Karaoke machines which are connected via fiber-optic links enabling them to provide instant high-quality music and video are becoming increasingly popular.
Karaoke direct is an Internet division established in 1997 been serving the public online since 1998. They released the first karaoke player that supports MP3+G and now[when] the KDX2000 model supporting karaoke in DIVX, Format.
One of long-running karaoke device is the DVD, HDD karaoke system, that comes with thousands of songs which popular in business such as karaoke machine rentals and KTV bars, and became popular in asia, especially the Philippines. This device also provides MIDI format with on-screen lyrics on a background video and scoring after you sing, the score will appear from 60 (lowest) to 100 (highest) based on timing and pitch.
The earliest karaoke-based music video game, called Karaoke Studio, was released for the Nintendo Famicom in 1985, 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.
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 China.
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. More usual is to contain the lyrics within the same MIDI file. Often the file extension is then changed from .mid to .kar, both are compatible with the standard for MIDI files.
Researchers have also developed karaoke games for cell phones to boost music database training. In 2006, the Interactive Audio Lab at Northwestern University released a game called Karaoke Callout for the Nokia Series 60 phone. The project has since then expanded into a web-based game and will be released soon as an iPhone application.
Since 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-Gs or laserdiscs, KJs[who] can \"rip\" their entire libraries onto their hard drives and play the songs and lyrics from the computer.
Karaoke devices in the 2000s saw a shift towards the use of hard drives to store large collections of karaoke tracks and touch screen devices that allows users to select their songs. This trend was driven by the declining cost of hard drive storage and improvement in touchscreen technology in the consumer space.
In 2010, a new concept of home karaoke system through the use of live streaming from a cloud server emerged. The earliest cloud based streaming device, KaraOK!, was released by StarHub on 14 January 2010, licensing songs from RIMMS. The use of cloud streaming allows for smaller devices with over the air updates compared to costly and bulky hard drive-based systems.
In August 2017, ROXI home music system launched in the UK, and later that year in the US, providing on-demand music streaming and a karaoke singalong feature called Sing with the Stars. ROXI matches songs in its cloud based licensed music streaming catalogue to a lyrics database to provide real time scrolling on-screen lyrics. The music system also uses a hand-held Wii style point and click controller with built-in microphone allowing users to select and sing along to thousands of songs from its catalogue.
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. Europe's first commercial \"karaokecab\" which was a London TX4 taxi with a karaoke machine inside for occupants of the cab to use to sing whilst in the cab. The idea and installation were made by Richard Harfield of karaokeshop.com and was featured on Channel 4's Big Breakfast and several German TV stations featured the karaokecab. Granada TV also featured the cab, which is now in its 4th vehicle and operates in Bolton, Greater Manchester as Clint's Karaoke Cab. Karaoke is often also found as a feature in aftermarket in-car DVD players. 59ce067264
