Filter type should be high shelf, not low pass.

Sorry , I cannot get any of the options to resemble the shapes in post 885. That is the inverse of the high pass recording characteristic shown here.

Balle,
for the Denon XG-7001 I use the following coefficients at 96KHz SR:
a[0]=1.0;
a[1]=-1.037628e-00;
a[2]=3.778493e-02;
b[0]=9.699928e-01;
b[1]=-9.542500e-01;
b[2]=0.0;

Sadly not, I calculated it only for 96KHz.

Many thanks,
then I get this= same at the Recorded characteristic, but I thought it should be the inverse to do the correction? . I do not understand well enough how the script works I guess

I wanted a way to depict on the graph which file0norm mode was used, and what the normalization frequency was. This is what I came up with:

Filenorm 0 A small star at norm point, filenorm 1 A colored Line at frequency

- #899
normalize = Frequency in Hz to set as 0dB in the plot
file0norm = 0 - normalize both files independently
1 - normalize both files to file 0 level
