I'm new to HifiBerry OS and also new to room correction in general. I did some measurements using the HifiBerry measurement microphone. But I'm not sure what the white, red and green lines in the graph actually stand for. Is there any explanation anywhere?
The "bass only" correction sounds ok and seems to make sense. However the other corrections to my ears result in distorted and extremely flat sounds. I'd be happy to know if they are worth trying at all, since "bass only" is default anyway ...
Below are screenshots of my "bass only" and "weightened flat" corrections.
