Questions about karaoke

[Silent One]

I have a question about the karaoke equipment used at Fanime this year. How did you guys used any mp3 and automatically converted it into a karaoke background song? The vocals in the mp3 just dimmed out as soon as the singer sings. I really want to know the software and equipment used in the karaoke.

Thanks,

Silent One

It's called Audio Hijack Pro.
