audio envelope follower/vu meter

I need to make a simple applet that plays an audio file and generates events from percussive attacks which randomly draw shapes. Has anyone seen any source code that has even something like a simple VU meter that I might scrounge through? I've been looking a little bit at some of the stuff like javax.speech.recognition.RecognizerAudioEvent but I'm slow at learning from inside the middle of an api, and this seems to be the right sort of thing, but from a distant approach. Surely someone can point me to a tutorial to something that might meet my needs?

thanks!
