Hi group
I just did a project that needed a Netflix dialogue gated loudness mix. I used the Supervision Netflix preset. The mix was -26,8LUFS.
If I use VisLM or Insight2 as dialogue gated loudness meter, the reading says -26LUFS.
I checked it on 3 different systems.
What is going on?
Best, Alan
Can somebody please replicate this on his/her system? Just grab a 5.1 mix with dialogue, measure it with Supervision (preset Loudness, Netflix, surround with dialogue) and do the same with Insight 2 (Netflix preset) or VisLM2 (Netflix 5.1 preset). Does it show the same outcome? On my systems there is a ±0,5LU-1LU difference (depending on the project/length).
Best, Alan
Hi Alan. 
To ensure that all plug-ins display the same information, they must use the same parameters. For example, the SuperVision and control room loudness settings must be set separately. (You must use the same values in the CR meter as in SuperVision.) Is this the case for you?
Thanks Mas, but the problem is between SuperVision and other loudness meters (like Nugen VisLM and Izotope Insight). I am puzzled why SuperVision has a +/- 1LU difference compared to theses 2 other meters, using the Netflix dialogue gated preset.
Best, Alan
That has always been a “problem” (between all Loudness meters, not only Supervision) and nobody seems to know exactly where the difference comes from.
The most stunning example is the difference between the hardware Dolby 737 and their own Dolby Media Meter where the difference is pretty much always more or less than 1 dB Leq(m).
Don’t worry about it.

I’m wondering if it is because you are using the mono version of insight rather than the multichannel 5.1 version? If anything it could be a good test to switch to the 5.1 version to see if there is a difference as well.
Looks like surround and not mono. You can see it on the Sound Field module in the middle.
Thanks for the reply @Exeter
In the picture it shows I am using the 5.1 version (see routing editor is at 5.1), so I don’t think that is it.
It happens with VisLM too, that measurement gives a 1LU difference, Insight gives 0,8LU difference.
Best, Alan
Ah yes I see I have my view setup differently for Insight so my eyes didn’t catch that.
