Laying down ambient background

Similar to how noise removal works, I would like to take a sample of the ambient background during a “quiet” part of the file, and then select a larger portion of the track, choose “Lay down ambient”, and have that sampled background noise duplicated enough times (and trimming the necessary amount in the final duplication) to put that ambient sound in the selected part of the sample.

Thank you for considering this suggestion.

Perhaps these plug-ins:
