My question is pretty simple. I want to Normalize my MP3's all to the same level of sound and loudness. When I click on "Normalization", I'm not sure what setting to use on "Level Detection" and what to set on the peak level., if I need to use it or leave it at 0db. On the "Advanced" tab, do I need to use it and if so, what do you suggest I set it to. Also, do I need to worry about compression and do I also click on "Automatic Gain Control"? I am not picky. As long as I get all the songs close to the same level that is fine. Any help would be appreciated. Thanks, Phil
