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.

File format edit

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.

Basic example:

[00:12.00]Line 1 lyrics
[00:17.20]Line 2 lyrics

[00:21.10][00:45.10]Repeating lyrics (e.g. chorus)
[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]

[ar:Lyrics artist]
[al:Album where the song is from]
[ti:Lyrics (song) title]
[au:Creator of the Songtext] [length:How long the song is] [by:Creator of the LRC file]
[offset:+/- Overall timestamp adjustment in milliseconds, + shifts time up, - shifts down i.e. a positive value causes lyrics to appear sooner, a negative value causes them to appear later]
[re:The player or editor that created the LRC file]
[ve:version of program]

Example with ID tags:

[ar:Chubby Checker oppure  Beatles, The]
[al:Hits Of The 60's - Vol. 2 – Oldies]
[ti:Let's Twist Again]
[au:Written by Kal Mann / Dave Appell, 1961]
[length: 2:23]

Walaoke extension: gender 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.


[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.

  1. Line 1 will use the default color (blue) when no tag is found.
  2. Line 2 lyrics start with red when F: is found.
  3. Line 3 lyrics start with blue when M: is found.
  4. Line 4 lyrics stays blue when no tag is found.
  5. Line 5 lyrics start with pink when D: is found.
  6. Line 6 lyrics stays pink when no tag is found.

A2 extension: word time tag 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 edit

[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>
