Removing Vocals from a Sound Track

Today i came across some work of one of my friends. To remove vocals from a sound track. Actually for it to be used as a karaoke. There is no easy ways to do this. This requires removal of frequency range of the voice of the singer. But always, it will overlap with the music frequencies. So you can not really get what you really want. But you can try and try and get close to what you want.

Here are some of the software i came across.

blazaudio - less controls of what we can do with the clip. But reduce the voice level of the vocals.

analogueX winamp plugin - They they, it reduces the vocals sound level, but i couldn't get working.

Adobe Audition 3 - An advance piece of software for professionals. Complex controls. But get's closer. With some experience with this software, you should be able to get what you need done.

Hope this helps if you also run into my problem.
