Frequently Asked Questions
What is an .LRC file and where can I use it?
An .LRC (LyRiCs) file is a simple text file with millisecond timestamps formatted as [mm:ss.xx] Lyric text. It is natively recognized by media players like VLC, AIMP, karaoke software, Kodi, and streaming distributors for synchronized on-screen sing-alongs.
Can I upload my own custom lyrics?
Yes. Select "Custom Song" in the preset dropdown, paste any song text line-by-line, adjust the BPM to match your target song, and use the Spacebar or Stamp button to generate your synchronized cue track.
Does this require an internet connection or upload my audio?
No. Everything runs strictly on your local device using native Web Audio and HTML5 Canvas. Your lyrics, timestamps, and audio processing never leave your browser.
