Answers.Body: <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>

Answers.Text: 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.

Answers.Text: 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.

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.

  In general loudness correction is a two step process. (There's a little more to it for full EBU R128 compliance, but I work exclusively in the US and this all that is required for A/85 / CALM Act compliance.)
  
  1. Measure the long term/infinite loudness of the asset.
  2. Shift the level of the asset by the difference between the measured loudness and the target.
