I revisited your initial post and think I misunderstood it the first time round. Are you saying that the interpolation errors are not equivalent to quantization error? Because that is how I understood it when doing my research. I was not being condescending. I was genuinely asking those questions, and to point out that if you have not done those hearing evaluations before, now is a good time. Let me just say that you cannot assume that everyone by default understands what you are trying to convey. It is more productive to avoid assuming ill intentions of others and clarify any misunderstanding during communication. When it comes to discussing new, and potentially complicated ideas, you cannot fault the listener for not understanding if you have not put in significant effort to make yourself clear, and it is particularly unhelpful to assume that another is simply not open minded. Providing additional links and resources to follow can go a long way to help other people understand the topic. That is of course only if you are genuinely invested to exchange ideas and learn new perspectives.
