I cant see any Issues on my site. But it could be that the Audio on your system get processed too slow. Maybe your Audio Drivers are faulty or any 3rd Party Software that allready processes the output before you hear it. Like Sonic Studio from Asus.

--- On this Site from the Dev are programms listed that interfere with Wallpaper Engine. Those programms also can fault Audio Lag for WE.

Hope i could help you

Thank you so much. I'll try.
