Hi Admin Team,
I have a question.
Concerning Loudness Analyzer.
What is meant by "real peak"?
True Peak?
When I analyze the same file by the Loudness Analyzer (real peak) and ffmpeg loudnorm (measured_tp) I get two different values.

Unfortunately this needs to wait a little but i notify hereby @admin so he has it in his notification list. He has currently a thing that keeps him from operating the PC.
Sorry i cannot answer this as i am not really familiar with any loudness stuff other than program loudness. Also reading the source code of the beloved anal_loudness processor (yeah, we all love this internal processor name
) just put up more questions than answers. So, let's wait until the Master of desaster is back...
What interpret in the source code is that we parse the ffmpeg output "Peak level dB:" into our true_peak variable but i do not have any clue what exactly ffmpeg means by "peak level dB:"

Hahahaha, yeah, that‘s right.
Maybe it‘s not a FFAStrans related issue but wrong setup of my workflow.
I‘ll make some more checks.
