Sound is something I’ve never really bothered too much about, but now Flash has some powerful abilities in this regard, awesomely demonstrated by HobNox’s Audiotool. So, dipping the metaphorical toe in the water, here’s a boshed together visualiser started with some code from Grant Skinner. It doesn’t use much of the data you have access to but the central burst represents left and right channel peaks and the white burst measures the left and right bass levels. Tune from the brilliant Dub FX.
