Detect Silence: how to achieve the opposite?

couldn’t you…

1. take a section of the “Fill” room noise and use the copy X-number of times, to create a “Fill” track.
   put a gate on it, have the dialog track side-chain the gate.
2. use detect silence on the dialog track so there is nothing in the holes where you want the “Fill” material

this would put fill material in all the holes of the dialog track.
