Default Normalization not consistent when imported into DaVinci or Audacity?

Hi

Already from 7.17 I noticed something about the normalization.

Summarizing:
I render the file (24bit 48kHz) with normalization on:
-10LUFS and -0.5TP

Apparently it normalizes the exported file BUT

then I import that wave into DaVinci and the result is really louder than the-10LUFS
So in DaVinci: right key on the audio, normalization, I setup -10LUFS -0.5dB TP and ... it reduces the loudness to real -10LUFS

Identical situation in Audacity. I import the exported Reaper File .. then I normalize the loudness to -10 and it dramatically reduces the loudness at the levels DaVinci does.

It's like the normalization is not correctly occurring in Reaper

Tested on my end:
  • Audacity 3.5 agrees with reaper: -10LUFS-I > -10LUFS-I
  • Cubase 12 agrees with reaper: -10LUFS-I > -10LUFS-I
  • Studio One 6.6 agrees with reaper: -10LUFS-I > -10LUFS-I
  • Da Vinci 16 (didn't update in ages) does not agree with reaper: -10LUFS-I > -23 LUFS-I

But it seems that Da Vinci normalizes to -23 LUFS-I no matter what you set.

no, DaVinci has the possibility to select exactly at what LUFS you need to normalize.
I have DaVinci 18.6.6

Audacity 3.5 as well. There is not agreement between Audacity and Reaper and between DaVinci and Reaper but Audacity is in agreement with DaVinci.

I still have this issue. I recogn it because I had the time to understand if it was my mis-setting or not. It seem they aren't.

I mean, even if i set -10 LKFS-I, the output is still -23. But might be a bug in version 16, i have this old version.

I'm pretty confident that REAPER is normalizing correctly. It's likely that the normalization settings used for comparison in other software are different. I don't know much about Audacity but a brief search shows that it will normalize mono files as dual-mono by default, which will result in the measured LUFS being 3 dB higher, meaning that applying normalization will reduce the loudness by 3 dB.

May be yes because I start using it in the 16.x.x so at that time I didn't know many features. However consider that I never had this issue before with Reaper and DaVinci.

Indeed in the past, when I exported at -14LUFS and -1TP, it always respected this.
By importing the wav into daVinci and by repeating the normalization, everything was consistent.

I start getting it form the 7.17 so far I remember, and I never had time to go through.

TOday I took my 10 minutes and damn ... the normalization is ON, parameters are setup but it seems it doesn't apply it. Graphically it does, but when I import the file into DaVinci is way louder.

I tested it into Audacity and I got the same ... hence I opened this post.

I will recheck the things however once again
