i must say that i dont heard the difference between flac and 320 cbr
then i will cancel all this about the spectral analysis
my hearing is great
...i dont know whats the problem,my hearing is great,the converteg song in ogg has had 736kb and it sounded the same like the flac file which has more than 20 mbhow can it sound the same??now im really confuzed and dont understand nothing anymore
(...)is it possible that i test that music somehow if it is fake mp3 320kbps (someone could convert it from 128 to 320 and upload that on the net as 320kbps)?
Just a hint on this: try some different tracks and positions, try to concentrate, e.g. on highs, on the stability of the room, on unnatural sounding instruments or on artifacts. Use acceptable headphones, listen in a quiet room. Repeat it later before you get tired.
