Thanks for your answer.
I allways try nmy best english and simplest expression..

But you understand at what I posted nad confirmed my thoughts.

Apodizing/standard upsampling- You mean the preringing its easier to hear on "live" or "natural" acoustic even when this pre-ringing is allways a "unnatural" hearing experiences for the brain ?
You mean when "more" natural acoustic is there, then "unnatural" sound its easier to hear as compared to when all the soundfield is "unnatural"?

Do you have an idea how the data transdered to the ID40 card?
Is that a industrial standard or what do you think?
