This is another way of incorporating the words, said or sung lyrics,
in the audio file as text, this time, however, in sync with the
audio. It might also be used to describing events e.g. occurring on a
<Header for 'Synchronised lyrics/text', ID: "SYLT">
Content type: $00 is other
Time stamp format:
$01 Absolute time, 32 bit sized, using MPEG [MPEG] frames as unit
Absolute time means that every stamp contains the time from the
beginning of the file.
The text that follows the frame header differs from that of the
Terminated text to be synced (typically a syllable)
Sync identifier (terminator to above string) $00 (00)
Time stamp $xx (xx ...)
The 'time stamp' is set to zero or the whole sync is omitted if
located directly at the beginning of the sound. All time stamps
should be sorted in chronological order. The sync can be considered
as a validator of the subsequent string.
Newline characters are allowed in all "SYLT" frames and MUST be used
after every entry (name, event etc.) in a frame with the content type
$03 - $04.
A few considerations regarding whitespace characters: Whitespace
An example: The "USLT" passage
"Strangers in the night" $0A "Exchanging glances"
would be "SYLT" encoded as:
"Strang" $00 xx xx "ers" $00 xx xx " in" $00 xx xx " the" $00 xx xx
There may be more than one "SYLT" frame in each tag, but only one
with the same language and content descriptor.
