Sound Equalizer

Hi,

I’m currently creating a equalizer for a webbased mp3player.
The visual part is a movieclip with (in my case) 15 frames.

[SIZE=“3”]I’m far from an audio expert and I have no idea how to handle this.[/SIZE]

What I would like to accomplish:
I want the movieclip to respond to the beat.
When a heavy beat (lets say 100%) comes around, i would like the playhead of the movieclip to gotoAndStop() to the last frame.
When there is no music at all, or some soft noise, the playhead should be somewhere around frame 1-3.

I hope u understand my question and I hope someone can help me.

Thanks,

Gertjan
