The Zingamp Karaoke doesn't have a function that can do this automatically. However, to do this, you need to open the program > press Karaoke > Preferences (or press the Ctrl + P key combination). In the Preference window, use the time correction tool from the bottom of the page to synchronize the lyrics with the sound. If the lyrics appear too late use positive values, otherwise use negative values. To be noticed that the values entered are in milliseconds. To save the settings, click Apply and then OK.
