Hi! Got a small question. I’m making a simple waveform audio visualiser. I’m using BitmapData and Bitmap.draw to create lines. And I want the drawing lines fade away to alpha 0 (or color white) in .1-.2 sec after being drawn. How can I manage this? I know how to blur them but not how to fade…  
Thx! :pope:
