Spek comparision of two 320kbps mp3s. File on the left was not ripped at 320 as you can see from the missing bandwidth from 15k to 20k (probably converted from a 128 or 192 rip). Most people could not actually hear that difference. What I could hear was that missing section from about 9.5k to 12.5k (yucky, think of a far away FM station going in and out). An actual 320kbps file should look more like the file on the right. #cosomusic
