I bought this gadget and it did not REMOVE the vocals from the any CD. It reduced the vocals volume but you can still hear it. Along with the reduction, the quality of the background music also dropped. Some of the CD gave some freeky sounds too....
To convert your CD's to Karaoke??? I doubt if this is the gadget you need.... I don't know if somebody has different opinion about this. If someone doesn't agree with me, please let me know the CD's and settings you are using to remove the vocals.
