Voice Cancellation (Karaoke?) in Vista

You can adjust an equalisation to cancel out more of less of some of the voice. sounds funny though but if anyone need to do that for whatever reason. The steps are:

1. Right-click the volume icon in system tray (Or go through control Panel)
2. Playback devices
3. Double-click your playback device
4. Enhancements > check "Voice Cancellation"
