Thanks Larry !

Loudness standards are gradually being required around the world with all broadcast media . These are defined in LUFS or LKFS .  Media producers are or will be required to ensure all media meets this requirement.

So firstly what is LUFS ? and secondly how do you measure it ?
The answer to the first is way over my head ( so best you look at this https://en.wikipedia.org/wiki/LKFS ) .
The answer to the second is far simpler, you need a LUFS Meter .

There are several available via Google , but let me save you some time and a lotta money. They range in cost from well over $500 to $25 .
Cost effectivness is me, so I purchsed LUFTS Meter plugin from https://www.klangfreund.com/lufsmeter/ for $25 . Which seems to do the same or better job as the more expensive ones .

Having installed it on my Mac mini on opening FCPX it was found under Effects > Audio > Klungfreud As below :

LUFS Meter Plugin in FCPX

I am not an audio tech. and my audio knowledge is limited to working with audio in my video projects and since audio is 60% of the message it is important to get it as good as can be . 
An audience will tolerate poor imagery, but NOT lousy sound -’nuff said !!!
 
The plugin should be placed at the end of any effects chain to achieve accurate readings . The really neat thing is that the plugin will also modify or correct the audio to comply with the standard set in the plugin’s Settings .
 
Larry Jordan is a highly respected FCPX guru and here is a demo of how to access and adjust audio effect and meters  in FCPX –

Update 5th Oct.: 

Wow! – I have just been trying out this plugin on past projects. 
First I reloaded a project in FCPX from my 2016 fcpx.library .
Using Command A, to select the entire movie, I then clicked on the selected clips and created a “New compound clip” Next I applied the LUFS plugin using drag’ndrop .
Now opening the LUFS Plugin graphic from the Inspector window I clicked the ” Adjust to ” My -23 setting and played the full length . FCPX then saved the revised/ corrected audio in the video project . 🙂

Now could that be any simpler ?
