Frequently Asked Questions
LRC is a plain text format for syncing lyrics to audio. Each line starts with a bracketed timestamp like [01:23.45] followed by the lyric text. It is supported by most desktop and mobile music players.
No. LRC has no styling support. TTML tts:* attributes are stripped during conversion. Only plain text content and timestamps are preserved.
Place the .lrc file in the same folder as the audio file with the same base name (e.g., song.mp3 and song.lrc). Music players like foobar2000 with Lyric Show Panel will automatically load and display the lyrics.
LRC only uses start timestamps. The TTML begin attribute becomes the LRC line timestamp. End times are discarded — LRC determines line duration from the next line's start time.
Yes. Files are uploaded over HTTPS and automatically deleted from the server after the LRC is ready for download.
LRC timestamps use [MM:SS.xx] centisecond format. TTML's millisecond timestamps are rounded to centiseconds during conversion.
TTML files are XML and slightly larger than plain text, but still compact. The 50 MB server limit is not a concern for subtitle files.
Yes. ChangeThisFile supports LRC to TTML conversion for round-tripping between formats.
Yes. All p elements are extracted regardless of which region they reference. The region information is stripped, and lines are ordered chronologically in the LRC output.
