Description hadmut 2021-10-31 17:23:37 UTC 
Normalize (2Pass) just doesn't have any effect. I had rendered a video twice, once without and once with Normalize (2 pass) filter applied to all audio tracks (and pressed the „analyze“ button), and it had just no effect, both videos exactly the same file in every single bit. 

Furthermore, it sometime shows error messages like

Normalize (2 pass)
[filter loudness ] Unable to load results: L: -13,016897 R: 2,646460 P 1,033092



(BTW: comes with the wrong default value of -23 instead of -14)


STEPS TO REPRODUCE
1. Load some video with audio track
2. render once without and once with normalize (2pass)
3. find no difference

Version 21.04 is the last version where the "normalize 2 pass" filter is working - since then the filter doesnt work anymore. Please fix that bug!!!
