Hello Everyone.

Just installed Flash CS3, and was anxious to get started with the computeSpectrum function, when I realized I am basically missing all the packages/classes needed…

It involves “events” / “utils” (byteArray) / and the media class.

How can this be? I’ve searched and searched, both my computer and [Adobe.com](http://Adobe.com) trying to download what I could. (One media package, which was the wrong one…) I have an “events” folder, but no Event.as class. (It was imported in the code I was trying to learn…)

Can anyone help me out? What am I missing?

Thanks.
