Looking for script to apply non-rt effect to all audio on a track

In this post at the DMN forum
"http://www.dmnforums.com/cgi-bin/tdisp.cgi?forum=sonic-foundry_vegas&post=030419174123.htm

a user describes a work-around for the 1394 payback freeze problem. The work-around requires one to add a non-RT effect to all audio on a track. (Actually, the goal is to create a new audio file and add it as a take, but what the heck...)

Anyone have a lead on such a script?

I've quoted Tommy's post to the DMN forum in the message linked to above.

Seems to me that all you would need to do is File-Render AS-WAV, delete the existing audio, then place the new WAV file in its place.

Now, if you want to fully automate the process, I suppose a script could be written that takes each audio event on the timeline, renders that audio to a new WAV file, and then replaces the audio with the newly rendered file.

Is this what you want to do?

To answer the question, the script should take each selected audio event, render a new wave file, and add it as a take to the event it was created from.

At first I thought that this work-around was a bit of a kludge since it was a round about way of just rendering new audio. However, it does a few elegant things:

It only adds a new take to the event
It leaves everything in place
Filters, buss assignments, envelopes, etc are untouched
Fewer keystrokes (on a clip by clip basis)
Your audio and video elements are still grouped together.

Rendering a whole audio track as a wav makes the individual clips uneditable. Remember this is a work around to the 1394 playback problem. If you need to do it at all, you'll want to do it as soon as the clip hits the timeline. You need to preserve flexibility.

For that matter, if using a script, you want to run it on all selected audio events-not on an audio track since you'll could be adding and removing clips throughout a session.

In addition to all this, it might be generally useful to have a script that will apply a Non-RT effect to a selected bunch of audio events. I don't think this is a special use script-it just happens to be handy for this particular work-around.

The script is available. It is called "Audio to new take" and can be downloaded from http://www.creativecow.net/articles/vegas_scripts.html

It is not very sophisticated and will try to use the same file names each time it is run. So, either only run it once or modify the file name between runs. If I get a little more time, I'll try to make the filenames more unique.

Thanks Ed!
