I just bought beoplay E8 earphones and am wondering how to interpret the four quadrants of the graphical EQ in the beoplay iPhone app.
Specifically, I am trying to understand what exactly happens to the frequency response curve (20hZ to 20kHZ on horizontal axis, +- dB change on vertical axis)) if I move the white dot towards the four corners: warm - bright on one diagonal, and relaxed - excited on the other diagonal? For example, is this correct?
towards Warm corner: bass is boosted, the rest of the curve is unchanged?
towards bright corner: bass is reduced, the rest of the curve is unchanged?
And which part of the frequency range is changed (boosted, reduced) if I push towards the Relaxed corner or the Excited corner?
Also, if I make the size of the white dot larger/smaller by pinching, what exactly happens to the frequency response curve?
