I think this is possible but I can’t find it.
Select a large shlog (techincal term) of clean room tone. Now select a tiny portion of show and paste only that portion of room tone that fits in the show. Duration of the show does not change. Do this completely automatically without knowing the fine details of in and out points and timing, etc.
So Punch Copy makes a clipboard in my abundant, spacious RAM and Punch Paste lets me select a tiny place in a show and replace it precisely.
But also, if you want to replace a long section, Paste will loop the copied audio to fit the space. This means that copying just a few seconds of room tone should be plenty - no need to fill your RAM with an hour of room tone.
no need to fill your RAM with an hour of room tone.
My RAM will be happy to hear that.
