[chuck-users] How can I filter silence?

I want to scan some audio for dropped out sections. It's long and talky with 'significant' pauses between question and answers. These sections are filled with background noise, and often several seconds long. I'd like to shorten these empty sections (there are a lot of them). I'd like to keep the files more or less intact (not sliced up into a zillion intermediate files) Is there a unit in chuck that will be able to delete samples as they pass through? Jim
