I didn't create this to bash 256kbps AAC files. I have a lot of songs on iTunes already and I am generally happy with them, but sometimes the quality frustrates me. Sorry it is my first post but I'm not a troll. I don't work in a music industry nor do I play any instruments. However, I can totally tell the difference between a CD track and a digital song, regardless whether it is 256kbps or 320kbps or AAC or MP3. I mean a lot of times air gushes out from sub woofers and you can feel it when you play tracks from CD, and you don't get that from files. And even CDs cannot seem to emulate the clashes and rides a drum kit makes when you are standing next to it perfectly, even with high end floor speakers with matching amplifiers and so on. Now I understand when people say things like 'pin drop sound at a concert/orchestra'. Am I crazy? Or is it true that people are just reluctant to admit that 512kbps is not the hard ceiling of sounds, its kind of like saying after 16 million color SVGA no one can tell the difference (look how much we progressed since then), or 'human eye cannot detect over 400ppi on a phone' (I can see the difference especially when you flick through the screens, it is just that technologically for the time being, it is not worth those extra ppi for price/power consumption/computing power needed etc) I don't think I have supernatural senses, nor do I think my senses are some sort of placebo effect. We are just being told 'be happy with the current retail standard, human can't tell the difference any further' right? Otherwise film industry and music industry would be not only be producing CD format and Blu-ray format, but also working with CD and Blu-ray format, which I am almost certain is not true.
