Plug-in for obtaining targeted LUFS and max Peak?

jeffagwm wrote on 5/7/2020, 10:34 AM

Does anyone know of any plug in that will instantly scan a file, provide the data on the file: max peak and LUFS, and then allow me to adjust parameters to specify the max peak and target LUFS for the file. I am Using Vegas Pro 17(Build 421). I know there is the Loudness log tool, but that is a little antiquated in that it generates a long txt file that you then have to scroll down to the end to find the the results. It does tell me the Integrated LUFS, but it doesn't tell me the max peak. It would be great it there is a plug in that will do all this inside Vegas to master the final output according to the various submission requirements of streaming services and broadcasters. Does any one know of such a plug-in that will work in Vegas?

YouLean Meter 2 or Melda MLoudnessAnalyzer

They don't scan the file. If you pay for YouLean, you can drag and drop the file onto the tool.

I recall trying an app that auto adjusted the integrated LU loudness but do not recall the name off-hand. It worked ok but was not free . I use Sound Forge 'Statistics' scan to get an integrated and other pertinent loudness readings. Unlike most real-time meters, the statistics scan is fast, scanning a 50 min program takes about a minute. Results can be copied/pasted if the b'caster wants a read out.
For instance, recent loudness statistics for a webcast:
Integrated Loudness (LUFS)       -16.27
Loudness Range (LU)       4.90
Maximum True Peak Loudness (dBTP)   -1.91
Maximum Short-Term Loudness (LUFS)   -13.14
Maximum Momentary Loudness (LUFS)   -9.91

If all of the necessary "raw" information is contained within the loudness log produced by Vegas, it would seem to be pretty straightforward to write a script that computes the required measures and also make some adjustments to the master audio bus. Since my understanding of audio is pretty limited, I would need additional information on exactly what is required.

The Loudness log does not give the max peak, just the LUFS info. The issue is that various distribution platforms have differing submissions requirements to which content must conform to be accepted. -24, -23 -19 - 16 Integrated LUFS and anywhere from -10 to -3 for max Peak at any point in the content. I am looking for a plug-in that would allow me to put in the desired parameters and it would increase or decrease the general level as needed based on my existing Integrated LUFS and the Target Integrated LUFS without exceeding (in the case of an increase in volume) the max peak target. Adobe claims to have something along this line (I haven't tried it) but I am wanting to work in Vegas.

@jeffagwm

As I indicated before:

Melda MLoudnessAnalyzer gives the information that you need and you can adjust the level accordingly in the plugin.

YouLean Meter 2 will give you everything that you need plus a graph that you can save and distribute, but you have to make the adjustment to the volume in the Vegas mixer.

Thanks to all who responded to this thread. In the end I went with Izotope Ozone 9 which includes the Maximizer plug-in which is providing me the function I was looking for.
