See, I have had trouble getting a straight answer as to whether we can tell the difference between some of these bitrates. I understand the lower bitrates are achieved by removing frequencies the human ear can't detect anyway.
Is there more to it than that? Is it a listening "skill" that anyone can develop, or is it simple physiology/age, etc?
I would love to do a truly blind A/B test and see if I could tell the difference between 128/256/320, etc.
