How does it work?
Karaoke Anything! uses a vocal removing technique that sums the left channel with the inverse of the right. It then places the results into both channels. We call it the "karaoke effect".
Many songs are mixed with the vocals being almost equally loud in both the left and right channels. This is done to give the effect of the vocalist being "center stage" when you play it back on your stereo.
When the karaoke effect is applied to this type of recording, the vocals will disappear or come close to disappearing as they cancel eachother out. Note: the "karaoke effect" does not work on mono recordings or in stereo recordings where the vocals are mixed off center.
