How to identify low volume/level audio segments in a recording?

Question

Iam newbie to Audition and trying to edit/master a 2 hour long lecture done in a live setting (not studio). Since the speaker sometimes moves away from the microphone the level of the audio sometimes falls off or reduces sometimes for a few seconds to a few minutes. I would like to identify all segments greater than 5 seconds which fall below say -5db.
I have tried using Diagnostics >>Effect : Mark Audio and set a Custom setting. I defined Silence has : Signal is below -5 dB, For more than 5000 ms (5 seconds) and Define Audio has Signal is above -15dB for more than 27 ms. It works to some extent in the sense it marks the Proper Audio segments in between the segments that are between the segments that are identified/marked as Silence but I would like the opposite. I would like to get the segments which are defined as Silence to be marked.
I am sure it is possible to do in Audition, appreciate all your help in figuring out how to do it.
To do the same in Audacity is very straightforward, Go to Analyze >> Silence Finder and define Treat audio below this level as silence : -5dB, Minimum duration of silence : 5 seconds. Thats it. That easy.
Would appreciate help from all the masters in the forum. Thank you for your time in advance.

Answer 1

Is what you are going to do when you have identified these sections to raise the volume. That can be done automatically without previously identifying them by using the Dynamic Processing or Speech Volume Leveling effects.
