The underlying technique in Audacity is to split the stereo track into its left and right channels, make both mono, invert all (or a selected part) of one of them then play back the result. Note, this removes everything panned in the center, not just vocals, and returns a dual mono result (both channels have the same audio). In some music this could mean removing instrumental parts. Removal of the vocals can often be incomplete leaving artifacts behind; this is especially true where there are backing vocals or where reverb (echo) has been applied as this spreads sound sources and makes them very hard to extract from each other.

In order for this to work you will need to have a studio version of the instrumental track in which the instrumental part is identical to the full track. Many studios release the instrumental tracks (with and without backup vocals) for use with things like karaoke. There are places online where you can buy these tracks (Karaoke-Version.com for example and some records even have them on the B side). MP3 encoding of one or both versions will create small differences that will make this technique less effective.
Finding an instrumental or karaoke version of a song can be pretty easy unless you're dealing with a song that isn't popular. That leaves you with just the full version of the song, complete with vocals. So how do you convert it into an instrumental or karaoke track?
However, there are ways to remove vocals or significantly lower them on any stereo song file to create a near-perfect instrumental or karaoke version. This guide shows you a couple of different methods using popular free and paid audio editors. These techniques can be audio, phase, or voice cancellation, configuring the equalizer, and using professional-quality machine learning tools that give the best results possible.

Karaoke (/ˌkæriˈoʊki/;[1] 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 usually 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.[2]
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.[3] 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.[19]
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.[22] 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.[23]
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.[24] 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.[25] 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[26] 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.[27]
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).[28]
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.[29]
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.[citation needed]
Karaoke Revolution, created for the PlayStation 2 by Harmonix and released by Konami 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 pitch, timing, and rhythm. The game soon spawned several follow-ups including Karaoke Revolution Vol. 2, Karaoke Revolution Vol. 3, Karaoke Revolution Party Edition, CMT Presents Karaoke Revolution: Country and Karaoke Revolution Presents: American Idol. 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.[citation needed]
A similar series, SingStar, published by Sony Computer Entertainment Europe, is particularly popular in the European and Australasian markets. Other music video game titles that involve singing by the player include Boogie and its sequel Boogie Superstar, Disney Sing It, Get On Da Mic, the Guitar Hero series starting with World Tour, High School Musical: Sing It!, Lips, the Rock Band series, SingSong, UltraStar, and Xbox Music Mixer.[30] 2ff7e9595c
