LRC (file format)

Lyrics
Filename extension .lrc

LRC is a computer file format that synchronizes song lyrics with an audio file, such as MP3, Vorbis or MIDI. When an audio file is played with certain music players on a computer or on modern digital audio players, the song lyrics are displayed. The lyrics file generally has the same name as the audio file, with a different filename extension. For example, song.mp3 and song.lrc. The LRC format is text-based and similar to subtitle files.

Simple format

Simple LRC format was introduced by Kuo (Djohan) Shiang-shiang's Lyrics Displayer. It was one of the first programs, if not the first, that attempted to simulate Karaoke performance. It usually displays a whole line of lyrics, but it is possible to display a word at a time, such as one would see in modern Karaoke machines, by creating a time tag for each word rather than each line.

The Line Time Tags are in the format [mm:ss.xx] where mm is minutes, ss is seconds and xx is hundredths of a second.

[00:12.00]Line 1 lyrics
[00:17.20]Line 2 lyrics
[00:21.10]Line 3 lyrics
...
[mm:ss.xx]last lyrics line

ID Tags may appear before the lyrics,[1] although some players may not recognize or simply ignore this.

Example of an Enhanced LRC file:

[mm:ss.xx] <mm:ss.xx> line 1 word 1 <mm:ss.xx> line 1 word 2 <mm:ss.xx> ... line 1 last word <mm:ss.xx>
[mm:ss.xx] <mm:ss.xx> line 2 word 1 <mm:ss.xx> line 2 word 2 <mm:ss.xx> ... line 2 last word <mm:ss.xx>
