Unlike most lyrics editors for Linux, it is self-sufficient, and does not depend on KDE or some external players.
It features full support for non-English languages, support for CDG, LRC and UltraStar specifics, and built-in karaoke testing window.
It has many unique features which are missing even in the expensive commercial software.
Unlike just regular lyrics available everywhere, lyrics suitable for karaoke players need to have timing marks which tell the player when to show a specific line, and when and how highlight the words. Export into the CD+G format is supported, as well as export into video. Currently supported formats include LRC, LRCv2 (supported by XBMC) and Ultrastar (without pitch). Karaoke Lyrics Editor is a program which lets you edit and synchronize lyrics with karaoke songs in various formats.
LRC: A text file containing lyrics with associated timestamps for each line, to be played with a separate audio file.Karaoke software uses some special file formats.
