After reading though that site, I decided to do a couple of tests. Using a fIREHOSE (Everyone loves fIREHOSE) mp3 encoded both in MusicMatch Jukebox and EAC, I did the Analysis in Cool Edit 2000. Damn, MM cuts of at 16kHz and the EAC created mp3 cuts off at 19kHz.

Looks like I got my work cut out for me......

My next question is I notice that most downloaded MP3s sound very 'hot'. My guess is I have never used 'Normalization' (yeah, so, I cant spell) , Is this something I should be using?
