A few months ago, I posted a question about comparing spectrums and I got a great answer using SPAN plugin.

However, this one is different. I want to take a snapshot of the current frequency spectrum and compare it with a different snapshot.
Adobe Audition has this feature.

Is there anyway I can do this in Reaper? Or can you recommend any plugins that can do this?
