It was not a blind listening test. As the bit rate increases the  
overall perceived quality is good and in some passages and for some  
type of music I can't distinguish 320 AAC from 192 AAC, but even at  
224 AAC for some music I can distinguish the difference in some  
particular points, brilliance in the attack to cymbals, bass  
profoundity, chorus neatness.

That sitting down test was done with Erykah Badu alone, the aim was  
to recode my library with a conscious compromise, but I listen a lot  
of music and always find some missing shades here and there. It could  
be I fool myself, but I'd bet I am objective.

I have to say that since my father was a professional musician I've  
listened to music at home since I had months, and studied it formally  
since I was six years old. I don't claim that comparison gives the  
same to everybody, it's clear people have different hearing resolutions.
