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.

A big THANK YOU for your article! This is what the user manual should have been! I followed it all the way through and successfully made the measurements, edit the curves, and uploaded to the receiver (Marantz AVR7012) , all in the First Try! However, the second try did not go so well. The app kept losing the receiver and I had to start over several times…… That’s probably is one of the reasons for low ratings. I finally noted your suggestion and use the IP address to "help" the app find the receiver. All my equipments are on a wired network, and the tablet was less than 5 feet away from the router. Never had any connection problem on wi-fi . Yes, the app is great , if it’s consistent. My cons are:
- Occasional loss of contact with receiver… "may" be handled by giving it the IP address to search on retry.
- Slow. It took me about an hour to upload the data to the receiver (AVR 7013 and Galaxy TAB-A). Many times I thought it was hung, but just waited it out.
Many thanks again for a very helpful article.
