Eh? Try that one again? I'm not understanding your query. Are you asking for a way for the actual graphical waveform to "influence" - ie FX? Is that it? In which, influence the video or audio?

Not possible with a script, probably not ever. However, it seems to me that it would be technically possible for a plugin to be written that could do this.

I think this stems from visualisations that use amplitude of audio as a modifier, for say, size on waveform on display (think of oscilloscopes).

There such plugs that exist and do have certain automated functions - but I can't for the life of me remember where I have seen them outside of Arkaos

If we're talking about using the waveform to influence graphical elements, After Effects can do this through expressions.

Not directly however it is possible with a plugin to write an envelope which you can copy to a video track and use that to automate an FX. From memory Grazie had a demo of this a couple of years ago.
I think the plugin came from Blucat, aderivative of their Classic VU Meter.
The problem is you have to play the file through in real time to get the plug to write the envelope. Once you've got the envelope then the thing is not too many / none of the video FX are controlled by envelopes, they all use keyframes. About the only things you can control are the composite envelopes.
About that time I did suggest it'd be cool if the video FXs could be controlled by automation envelopes instead of keyframes and someone from SCS thought that'd be a neat trick that no other NLE can do but it never happened. I thought it'd be great to drive the CC FX from one of these (on special recently for $9K). Why should the audio guys get all the bling with their Mackie HUIs?

Without going to far OT - but since you mention the JL - then possibly the new Euphonix Artist stuff could be useful... Depends on how the touch screen is implemented, and if it becomes windows (which I hear it is, but no concrete evidence)

Euphonix advertise that their control surfaces will work with Vegas. I've heard a rumour that they'll be given one away as a door prize at the Vegas NAB party, you got get it home yourself though :)
Don't know about the touch screen HUI but if their big desks will work I can't see why the touch screen couldn't.
Damn, now you've got me thinking, how about running the Vegas mixer off a Wacom touchscreen. Seems to me all the work is already done.

As I think RNL said, this is a job for AfterEffects. I think I saw a tutorial covering this in one of the Trish and Chris Meyer books a few years ago.

You might, maybe, find some VJ software that can do some things to your video based on the audio, but the good VJ tools cost money that's be better spent on AfterEffects, unless you're actually mixing video for big parties and dance events.

It *may* be possible to somewhat simulate this.

If you use the Blue Cat Peak Meter control, it can draw an envelope when you play back the timeline based on the volume level. Once the envelope is drawn, you could the COPY that envelope (or use a script to read the envelope points) and paste/write them to another envelope and then that would basically be controlled via the waveform.
