LRC (file format)

From Wikipedia, the free encyclopedia
Jump to navigation Jump to search

LRC (short for LyRiCs) 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[edit]

Simple LRC format was introduced by Taiwan-based Kuo (Djohan) Shiang-shiang's Lyrics Displayer. It was one of the first programs, if not the first, that attempted to simulate Karaoke performance[citation needed]. 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. Kuo's Lyrics Displayer was created in 1998 and was accompanied with a plug-in for Winamp.[1]

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.

  • Normal example:
[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,[2] although some players may not recognize or simply ignore this.[citation needed]

Simple format extended[edit]

Available only in Walaoke from Walasoft. The ability to change and specify the gender of the lyrics by using M: Male, F: Female, D: Duet.

  • Example:
[00:12.00]Line 1 lyrics
[00:17.20]F: Line 2 lyrics
[00:21.10]M: Line 3 lyrics
[00:24.00]Line 4 lyrics
[00:28.25]D: Line 5 lyrics
[00:29.02]Line 6 lyrics

Let's say we use blue for male, red for female and pink for Duet. Line 1 using the default color (blue) when no tag is found. Line 2 lyrics start with red when F: is found. Line 3 lyrics start with blue when M: is found. Line 4 lyrics stays blue when no tag is found. Line 5 lyrics start with pink when D: is found. Line 6 lyrics stays pink when no tag is found.

Enhanced format[edit]

Enhanced LRC format is an extension of Simple LRC Format developed by the designer of A2 Media Player.

The differences:

  • The line timestamp is the end of the previous word.
    • This allows LRC players to determine the duration of the previous word, and when to display the next line.
  • Adds a Word Time Tag in the format: <mm:ss.xx>.

Format example:

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