what is the width of the "q" parameter in Rockbox EQ?

<< < (3/3)

Why are you trying to flatten the frequency response of a IEM?  A flat response for them is wrong as they bypass the outer ear (and to a lesser extent the head).

The peak around 2~3khz is external ear resonance.
And that image seems raw response graph. You shouldn't bulldoze it. That's normal.

If you like er4p sound reference to this image.

What I said flat was ~99% diffuse field referenced.
