I have just purchased my first iPod and I have noticed that the MP3 files I have ripped from my CD's often have very different volume levels. I have noticed that iTunes allows you to manually adjust the volume levels, but I have 4.12 GB of song files that I have ripped. Isn't there a utility that works on the same principles as iEatBrainz, can sample each files output volume and automatically adjust all files to a preset level? Cheers, Brian
