Wiki opisuje to tak:
XBMC Media Center supports the following Karaoke features:
Supports CDG, LRCv1 and LRCv2 lyrics formats;
Supports UltraStar song lyrics and video formats;
Supports MIDI music and KAR files;
Plays directly from MP3+CDG archived together;
Supports song numbering with permanent numbers, which means the song could be selected by number, even if another song is being played. The numbering information could be exported into HTML file and used to print catalogs.
Supports real-time lyrics timing modification, allowing to modify the lyrics-music delay. The delay is associated to the song, and then restored when this song is played again.
Supports different background modes, including visualization, still picture or video.
Configuration
XBMC Media Center needs to be configured to support karaoke. You need is to enable karaoke in the Setup -> Music -> Karaoke. I also suggest to disable "Music -> General -> Auto play next item" as it's usually not desirable for karaoke.
Playing
Select the Karaoke song (either on disk or by number) and press "Select". The screen should change to visualization, and the song should start playing with the lyrics shown on screen. For us the best visualization for karaoke so far was Goom, but it is very resource-consuming so if your hardware is not top notch, you might want to switch to Project M instead, which is also very good.
If the lyrics for this specific song need to start earlier or later, press the button associated with SubtitleDelayPlus or SubtitleDelayMinus until lyrics are synchronized. Each press changes the delay by 50ms.
If you're in the middle of a song and decide you want to hear something else, press x to get back to your song listings. You can also move through your songs lists by pressing , or . to go backward or forward in your song listings.
