Apple Syllable	Records the start and end time of phrases, includes performer information for each line of lyrics, includes background vocals information	Apple Music syllable-by-syllable lyrics, can be imported by administrators

LRC Format Specification

Header Information

The header of the lyrics can optionally include relevant information, such as:

[ti:Counting Stars]
[ar:OneRepublic]
[al:Native]
[by:Wang]
[offset:0]

Note: Do not include duplicate tags.

Lyrics

The standard format for LRC lyrics is:

[timestamp]lyrics

timestamp is the timestamp indicating the start time of the line of lyrics.
The timestamp should follow the ISO 8601 standard, formatted as mm:ss.sss, and should not be written as mm:ss:sss.

Here is an example:

[01:17.870]Lately, I've been, I've been losing sleep
[01:21.390]Dreaming about the things that we could be
[01:25.390]But baby, I've been, I've been praying hard
[01:29.390]Said no more counting dollars
[01:31.210]We'll be counting stars

Note:

LRC lyrics do not allow duplicate timestamps, but multiple timestamps for the same line of lyrics are allowed, as shown in the example below:

Not allowed:
     [01:17.870]Lately, I've been, I've been losing sleep
     [01:17.870]Dreaming about the things that we could be
Allowed:
     [00:01.670][01:17.870][02:28.640]Lately, I've been, I've been losing sleep
     [00:04.850][01:21.390]Dreaming about the things that we could be

LRC lyrics allow out-of-order timestamps, such as:

[01:25.390]But baby, I've been, I've been praying hard
[01:21.390]Dreaming about the things that we could be
[01:29.390]Said no more counting dollars
[01:17.870]Lately, I've been, I've been losing sleep

If there is a long musical gap (e.g., greater than 5s) between two lines of lyrics, it is recommended to add a blank line with a timestamp equal to the end time of the previous line, which can create the “Breathing Dots” effect in the Apple Music lyrics interface in Lyricify 4.
```
[00:16.36]We'll be counting stars
[00:19.28]Yeah we'll be counting stars
[00:22.89]
[00:38.05]I see this life like a swinging vine
[00:40.67]Swing my heart across the line
```
A blank line can be added after the last line of lyrics, with a timestamp equal to the end time of the last line of lyrics.
```
[04:11.66]Sink in the river
[04:12.60]The lessons I've learned
[04:13.79]
```

Creation Tools

It is recommended to use the following tools to create LRC lyrics.

Lyrics Scrolling Princess (https://lrc-maker.github.io/)
BesLyric (https://github.com/BesLyric-for-X/BesLyric)
BesLyric-for-X (https://github.com/Beslyric-for-X/Beslyric-for-X)

QRC Format Specification

Header Information

The header information for QRC lyrics follows the LRC standard and will not be repeated here.

Lyrics

The standard format for QRC (Lyricify standard) lyrics is:

[start,duration]Word (start,duration)word(start,duration)

start is the start time, and duration is the duration.
The timestamps in [] indicate the start time and duration of the entire line of lyrics.
The timestamps in () indicate the start time and duration of the preceding word.
Timestamps are positive integers, measured in milliseconds (ms).

Here is an example:

[358,4575]Lately (358,1336)I've (1694,487)been, (2181,673)I've (2854,268)been (3122,280)losing (3402,345)sleep(3747,1186)
[5245,3864]Dreaming (5245,696)about (5941,471)the (6412,306)things (6718,458)that (7176,292)we (7468,511)could (7979,393)be(8372,737)

Note:

QRC (Lyricify standard) lyrics do not allow duplicate timestamps and do not allow out-of-order timestamps. Lyrics should be sorted by time (except for background vocals, which will be discussed later in the Creating Background Vocals section).

QRC (Lyricify standard) lyrics allow overlapping lyrics time segments (i.e., multi-line highlight), such as:

[124571,2326]Won't (124571,575)we? (125146,459)Yeah(126404,493)
[125613,1118]Won't (125613,483)we?(126096,635)

Creation Tools

It is not recommended to manually create QRC lyrics, as manual timing is very difficult, making it hard to relax and resulting in low accuracy.
If you still want to try creating QRC lyrics manually, it is recommended to use the following tools.

ALRC (https://github.com/kengwang/ALRC)
QRC Lyric Maker (https://github.com/BPTPW/qrc-Lyric-Maker)
Lyricify Word-by-Word Creator (embedded in Lyricify 4, not recommended for use)

Note: These tools are quite rough, providing very limited functionality and having many issues, so it is strongly advised not to use them.

YRC Format Specification

Lyricify Lyrics Library does not support the import of YRC lyrics. This section is only an introduction to the YRC format.

Header Information

The header information for YRC lyrics may include Lyricist, Composer, etc. Here is an example:

{"t":0,"c":[{"tx":"Lyricist: "},{"tx":"Brent Kutzle"},{"tx":"/"},{"tx":"Tyler Spry"},{"tx":"/"},{"tx":"Steven Mudd"},{"tx":"/"},{"tx":"Ryan Tedder","li":"http://p1.music.126.net/S06CeorJXg0Rgb6KhTB9pQ==/18969874114079440.jpg","or":"orpheus://nm/artist/home?id=42602&type=artist"},{"tx":"/"},{"tx":"Josh Varnadore"}]}
{"t":1000,"c":[{"tx":"Composer: "},{"tx":"Brent Kutzle"},{"tx":"/"},{"tx":"Tyler Spry"},{"tx":"/"},{"tx":"Steven Mudd"},{"tx":"/"},{"tx":"Ryan Tedder","li":"http://p1.music.126.net/S06CeorJXg0Rgb6KhTB9pQ==/18969874114079440.jpg","or":"orpheus://nm/artist/home?id=42602&type=artist"},{"tx":"/"},{"tx":"Josh Varnadore"}]}

The specific meanings are left for interpretation.

Lyrics

The standard format for YRC lyrics is:

[start,duration](start,duration,0)Word (start,duration,0)word

start is the start time, and duration is the duration.
The timestamps in [] indicate the start time and duration of the entire line of lyrics.
The timestamps in () indicate the start time and duration of the following word.
Timestamps are positive integers, measured in milliseconds (ms).

Here is an example:

[54260,3090](54260,900,0)Stop (55160,480,0)and (55640,1710,0)stare
[57380,5130](57380,150,0)I (57530,600,0)think (58130,180,0)I'm (58310,690,0)moving (59000,420,0)but (59420,150,0)I (59570,690,0)go (60260,2250,0)nowhere

Apple Syllable Format Specification

N/A

Creating Background Vocals

Currently, only QRC (Lyricify standard), Lyricify Syllable, and Apple Syllable support “background vocals”.

QRC Lyrics

Under the Lyricify standard, QRC lyrics that meet the following rules will be displayed as “background vocals”.

The lyrics start with ( or （ and end with ) or ）.
The preceding and following lines of lyrics do not meet Rule 1.

Note: Background Vocals lyrics lines should be placed below their main lyrics line, even if their timestamps are earlier than the main lyrics line.
Here are some examples:

[122385,1295]Yeah, (122385,343)won't (122728,451)we?(123179,501)
