<p>Audition has a couple of tools that lets you measure loudness. There's the Amplitude Analysis window that lets you scan a whole mix or sound file, and tells you the LUFS loudness (<a href="http://gameaudionoise.blogspot.com.au/2012/02/whats-difference-between-lkfs-and-lufs.html" rel="nofollow noreferrer">which is the same as LKFS, aparently</a>):</p>

<p><a href="https://i.sstatic.net/crLkL.png" rel="nofollow noreferrer"><img src="https://i.sstatic.net/crLkL.png" alt="enter image description here"></a></p>

<p>There's also the "Loudness Radar" that has a sexy GUI, but seems to only scan in real time (though I might be using it wrong).</p>

<p><a href="https://i.sstatic.net/hnPgZ.png" rel="nofollow noreferrer"><img src="https://i.sstatic.net/hnPgZ.png" alt="enter image description here"></a></p>

<p>If you use the former you have to manually apply gain to correct for your target loudness, if the latter you can have it apply correction to reach your desired level (hit the settings tab to choose).</p>

There's no manual approach in my opinion because as readed around the broadcast requests have to be done via an algorythm. About Loudness Radar I saw people using plugins like that in automatition and "write" latch mode. So that the plugin itself does that for you, one of them is [Waves Loudness Meter plugin](http://www.waves.com/plugins/wlm-loudness-meter) like in this video: https://youtu.be/KsmkntnD1bA?t=1514 however I'm not sure if this can work also in Audition with this plugin or if waves one could works with Audition too and used in "write" mode in the same manner.

The manual process is that you just apply the correct gain. E.g. for the above item you need to apply -2.7dB gain to get it to -24 LKFS. You apply it to the whole program, it's not an instantaneous thing. That's what I do when I need to prep things for broadcast.

<p>No "audio adjustment layers" in Premiere.</p>

<p>My suggestion would be to go the "master output way": edit your piece with what you have (I assume here that everything has the same specs, audio and video wise), do an audio mix-down, and play with gain/volume etc until you get what you need.</p>

<p>Do a test before getting in the proper editing though: create a rough 30s edit, mix it, do a mix down and play with gains/volume etc. to respect your notes. Test the exported file to see if it respects the directions.</p>

Sorry but this is not what I'm looking for. I need a filter that conforms everything for me. Because in this part of the process I'm not the director or part of creative process, I just need to glue 2 audio and video together in an MXF file, but I need to be sure that everything is all right. TL;DR: the manual way is not a way for me. I'm not an audio specialist, I just have to output the MXF properly.

The actual answer from @Michael Liebman is to follow. In short, I researched a bit, you have to measure the Loudness over all the piece, also is an automated process that must be done via plugins, it follow various alogrythms and is not something that you can do manually at all. The one you was referring at was the old measure with RMS.
