Hi,
I can't find where to set a reduction value for the Final peak remover in the clipper advanced parameter.
When I import one of your preset, there is a -1.5dB TP value defined that is not exceeded, but I can't find where it fits ? (See screenshot)
Can someone help me ?
Sincerely

What preset?

Check Post-amplifier level.

I don't understand I activate not to exceed 0db, I lower the post amp and yet in icecast reception I receive +1.2 dB True Peak.
Even with -3dB in post amp

Then it's not codec, something else is wrong.
Can you post link to streams?

What I don't understand is that when I turn down the post amp even to -5dB I still get peaks at 0, -0.2 -0.5 dB TP....
