Editing Your Curves - Target Sound Options
You can choose between two, uninventively called High Frequency Roll Off 1 and High Frequency Roll Off 2. Contrary to what many audiophiles believe, fundamental frequencies at about 15 kHz is piercing uncomfortable for young people. Almost all audiophiles cannot hear frequencies about 15 kHz (most probably cannot hear past 12 kHz). Do not get alarmed by the downward slopes.
Note the dip at the 2 kHz band, this will be explained further in the next page.
So which filter should you use? It depends on your gear, your room and most important of all - your hearing. Take the Yanny vs Laurel test. If you are hearing Laurel all the time choose filter 2. This is a steeper roll off and should give you a better audio quality perceptionally.

The hints how to copy and rename curves helped me a lot. Unfortunately the app is often not self-explanatory. Many thanks for your work.
