Wavelab element 9 Dithering

Hi, everyone
I’m with wavelab element 9
I want to add Dithering
There are two possibilities
The guide does not explain too much
And this is the explanation from the guide — Noise Type
Sets the noise type for adding to the signal.
• In No Noise mode, no dithering is applied.
• The Noise Type 1 mode is the most all-round method.
• The Noise Type 2 mode emphasizes higher frequencies more than Noise Type 1.

Happy to help
Thank you
