Okay so I was in the process of catologuing my 7500-odd MP3s and burning a few of my favs onto CD. These songs have all been accumulated from various sources, formats, etc, over the past 5 years. So they were not all pulled from the same person or with the same ripping software.

I was recently listening to one of the discs I made and I noticed quite a change in volume/ambience of one song to the next. It wasn't the case with all of the songs, but maybe 20% of them on the disc were significantly louder than the others I deemed "normal" at the volume setting I had chosen.

Getting to the point, is anyone aware of a program that can 'fix' these mp3s to an 'average' volume across the board, versus the volume variety that I seem to be encountering? Also, is 'normalization' have to do with what I am referring?

Well, use iTunes only, ever. There are volume levelizationism settings.

Yes it does. If you're interested in permanently changing the files you are using. But taking an MP3, converting it to an uncompressed format, normalizing/upsampling the volume, then applying MP3 to the results is pretty much not going to be worth all the effort. Especially if the original was of marginal bit-rate to begin with. But most semi-decent sound tools (you may need a separate program that will convert MP3s) can do this thing you ask.

I use MP3DirectCut, recommended to me in my soundfile-thread.

Like UM said, iTunes has this under preferences enable "sound check" I believe it is called. It works pretty well. Also you can use the uber-cool music store....

iTunes also goes to 11.

I wish that I could use the iTunes store, but since they don't support Paypal, my dad won't let me. [Frown]

As soon as I get a permanent job that can support it, I'm gonna sign up. Hopefully.
