Create a karaoke

Its possible, but it requires software. Generally, the lead vocal of a song recorded in stereo is equally present in both left and right channels. In simple terms, to render the song as karaoke, you subtract the centered vocal from the music tracks. A number of programs are available to do this - some free, some not, and of course, features, function, and performance vary.

Thanks, that's good news. Where do i get these programs from.
