Hello Alexander,

I wrote that module some time ago. And I had the same problems that you 
describe, i. e. when I tried to avoid clipping in the worst possible case, the 
output was way too quiet.
Therefore I tried to come up with a heuristic and the 1.2 fudge factor seemed 
to work for me. But you are right that it depends on the HRIR and the content 
and I also came across situations in which there was clipping in the meantime.
So this is definitely something that should be fixed.

Kind regards,
