Editing Sound on Karaoke CD+Gs. Can it be done?

Hi,
I want to have live musicians playing to Karaoke CD+Gs rather than have the pre-recorded tracks audible to the audience, having the prerecorded Karaoke music just on the musicians ear phone monitors, so the only music the audience hears is the live musicians. I want to add 2 beats to the CD+G music track in front of the start of the music so the musicians know when to start playing, as they need to be in sync with the words that are projected on the screen.

Can it be done? And if so, will adding to beats to the audio track affect the original synchronization of words and music?
Finally: HOW???

Thanks
Lawrence Brand

As a musician, I would find this method very irritating to play along to. Especially for the drummer.

But if you want to try, there are several problems:

1) You would need special CD+G burning software that can properly interlace the graphics with the audio. If that exists then you've crossed the first hurdle, but I can't say for sure.

2) You would also need to edit the graphics data so that it syncs up properly. In order to do that you need more special software.

If you can pass both of those hurdles, the Audacity part is easy. Generate a click track that is two measures long at the song's BPM, import the wav file, use the Time Shift tool to shift the wav file so that the first beat of the song lines up with the first beat of the second measure (I recommend using a whole measure instead of 2 beats). Finally, export your new wav file.

After that use your special software to burn the disc with the new graphics data interlaced. Viola!

Should be possible. Something like CDG Ripper to get at the separate audio and graphics files, edit the audio and the graphics files then burn them back to a CDG disc (e.g. Power CD + G burner)
