A number of applications were discussed in this thread.

Here's the bones of it. The CALM Act.

TB_EBU from Toneboosters will do it for you. The trial is free; the only limitation is not saving presets, which is of little importance to me.

HINT: If you normalize to A85/ATSC, your audio will also pass muster in the EU (EBU_R128).

Vegas has the tools built in to help with this.

Open the new Loudness Meters and tweak your mixes to maximize audio dynamic range while you maintain consistent -23 LUFS Integrated levels and create EBU R-128/CALM Act compliant renders that will pass unattenuated through every stage of any contemporary broadcaster's signal path. The result: perfection, with your audio delivered to viewers in a state as dynamic and pristine as when it was rendered–exactly as you intended–regardless of playback system.

That was Vegas 13, correct?
i thought Vic was on Vegas 12, but I may be mistaken.

Don't know what Vic uses.

Yes, this is Vegas 13.

Point is, we provide a solution to the problem.

Which is wonderful, I might add!
I'm not on 13 yet, either. Maybe by winter.

But won't V14 will be out by then ?

(Joke, just to clarify .....)

I wouldn't exactly call a loudness meter a "solution". It is a necessary measurement tool that one could use to provide a solution if they had the audio chops to use compressors and limiters and mix their audio correctly. All by itself, the loudness meter doesn't "solve" anything.

What would be a solution is for Sony to develop an audio plug-in much like the Broadcast Colors plug-in for making video broadcast safe, but for audio (e.g., Broadcast Audio plug-in). Since you have the loudness information from the new meters, you could use that to attenuate the audio automagically.

BTW, Adobe CS6 and beyond already has this in their Match Volume function of Audition. One button... instance CALM Act compliance. This is what Vegas Pro needs and would actually "solve" Vic's problem.

If I had the programming chops to write it I would but I don't... hopefully someone at Sony does. ;-)

Most eloquently reasoned Mr R. I heard you in London.

I don't have VP13 either but SF Pro-11 has a LKFS meter utility. It can meter momentary , short-term, integrated and overall loudness in real time.. or.. for fast entire program calculation and submissions, can render a log.
Otherwise, there are plug-ins available. AFAIK, the 'freebies' can't render a log.

addendum: -13.8 LKFS !!! .. no wonder it got tossed back. Must be compressed to sh_t and up around 0dBFS.
FWIW, ATSC A/85 'usually' works out to max peak around -10dBFS, but can be higher or lower depending on compression and other factors.

ATSC A/85 is -24 LKFS,. EU_R128 is -23 LUFS, conservatively the same. As expected, broadcast advertisers push the limit up to about -22 without much notice. The rest (new car commercials, movie teasers) are horrible. But no one's brought class action yet, as far as I know.

The one broadcast advertiser who continues to amaze us is Intel, whose symphonic backdrops utilize full dynamic range, but stay right in the pocket with integrated loudness. It's how the standards were meant to be exploited, but not abused.
