when it comes to audio peaks...

and compression and limiting, what do most networks expect? i get the feeling that they don't like tracks the limit/max at 0. i also get the feeling that they like to do their own compression. as an audio guy, originally, i like compressed/peaking at 0 sound. but is it what a TV network wants? what's your experience?

Are you in the US?
ATSC/A85 is now the law. Even long-form content (not just commercials) should be conformed to -24LUFS.
Compression is your choice but the loudness and true peak volume are regulated.
If you're in the EU, the similar standard is called EBU R-128.

Why doesn't Sony Vegas have an LKFS meter as an audio effect or plug-in? As you point out, LKFS metering is the law. I am editing a tv program for a cable channel and I must make sure I am within -22 to -26 LKFS . The only way I can check my work is to load my render into Adobe Premiere and use the TC Electronics plug-n THAT IS INCLUDED with Adobe Premiere and Adobe Audition. I see that Sound Forge has some LU metering but if I have to run my audio through another app I might as well keep using Adobe. They are WAY ahead of Vegas in this area. I have tried a couple of third party plug-in's but they all measure differently and do not have the same specs as the ATSC/A85. They can be "off" by as much as 2 db. I only have a 5 db slot to work in. I have spent a lot of time trying to find a solution. When I ask anyone about it they just say "why don't you edit in Premiere?" I say, "because I like Sony Vegas much better. The cable channel doesn't even recognize Sony Vegas as a professional grade NLE. That is why I can't imagine why Vegas doesn't have a viable solution to LKFS metering. Just mind boggling.

GaryG - you have hit the nail on the head and as you might suspect SONY QC (quality control , folks) is monitoring this conversation as we speak. BUT here's the problem unless enough of you and I place this in the suggestion box for improvements there is little chance that Vegas development is going that route.

Sound Forge accepts VST on the 5.1 master bus. Thus plugins like Nugen and Tonebooster should work across the board.

In order for this to happen in Vegas, they would first have to enable 5.1 VST support. I know personally of several feature requests going back years that have fallen on deaf ears. Thus, third party plugins are good on the stereo master only.

As far as Sony implementing their own solution, it would be a licensing arrangement with one of the few third party commercial developers, adding $ to the cost to the end user. TANSTAAFL.

Thank you for the response. Your reply, while honest is very dissappointing. Am I the only person using Vegas for broadcast? Since the CALM act went into effect last year, and given Sony's audio roots in the digital editing, it's just difficult to imagine their silence on this issue. I will keep searching for a reasonably priced third party solution. Thanks again for your insight.

Seems like I tried to download and install a VST plug-in with metering a couple of months back. Can't recall where I found it. I was unsuccessful with it so I moved on. Thanks for the reply.

The Toneboosters plugin trial doesn't expire, and they update regularly. You just have to drag the files to your VSTPlugins folder And the paid version is only 10 EU. It agrees exactly with Nugen. I use it almost every week (on the stereo master).

Awesome! Just downloaded and installed, and it seems to work just fine. At first I thought it was only for EBU R128, but found the LKFS ATSC A/85 setting. This is exactly what I was looking for. I can't thank you enough. I will be happy to pay for this.

Free version you can't save presets or rather: "Parameter saving is disabled". Paid version is EUR19.95 :-

I stumbled over this some months back when I was about to cough up for a rather more expensive iZo plug.

Thanks musicvid10 for pushing me over the curve.

SF11 has the EBU and ATSC loudness meters as well.. but they're not plug in and can't be used in VP or other NLE/DAW.The Tonebusters meter works great for me.. as does the free Audiocation AC-R128 meter. https://www.audiocation.de/en/plugin
All confirm the same loudness.
