Hi
Understand your concern and agree on the need, unfortunately, this effort and request will probably take a couple of months before having a release available to the public. It comes to mind that when the signal goes below a threshold, you can freeze your gain derivation to cover for that corner case. There are probably other ways to come up with this value by using other blocks or even Dynamic Processors. I do know for a fact that some other compressors in the library do give access to this info.
Do you need us to post some examples?
Regards
Miguel
