You can tell the difference between 320kbps and a wav file across a wide range of music? You might want to try and get in contact with a competent researcher in this area as they may be interested in studying you
Hehe, absolutely no. A 320 kpbs MP3 and .wav are hard to distinguish, but the high freq range is usually the one where things are missing, and the lows also but only if there are a lot deep sweeps and bass. If I wouldn't have a wav and an mp3 for comparing I wouldn't be able tell the difference. I don't have the high-end headcans or the finesse for that.
