Creating room tone for gaps in Audio. (Using AI?)

[WontYouPleaseHelpMe]

Please read this post closely before responding. It is a very specific problem. As an Video Editor of feature films and Television shows I often find myself looking for non dialogue room tone to fill in spaces in my audio tracks. There does occur spaces in my audio tracks where there is nothing on the timeline and I need to put in some room tone. This is typically done by looking for quiet bits in a take and cutting them in. Can this process be automated?

Please do not suggest using "sound enhance" and clogging the post this is not the question. I already know how to clean-enhance up BG with Premiere audio enhance. This is just about filling holes with roomtone that can be so aggravating and time consuming to find and edit into an audio track. 

Thanks

Generative Extend, released in Premiere Pro 25.2, can do this. If you use the tool only on audio, it will extend only the audio, up to 10 seconds. It specifically does not create voices, only extending the ambient sound. More information: https://helpx.adobe.com/premiere-pro/using/generative-extend.html

You can find long pauses using the Text panel in Premiere Pro.

First, transcribe the clip in the Text panel. Then open the Transcript View Options (settngs icon in the bottom right of the Text panel), and adjust the Minimum Pause Duration slider to define what counts as a "long" pause.

Next, click the Filter icon (funnel icon), select Pauses, and apply the filter. This highlights all pauses that meet your set duration. You can then step through the results to find the one that fits your needs.

Tip: Use the Remix tool (in the Tool panel) to loop the pause to any desired length.
