MP3Gain analyzes and adjusts mp3 files so that they have the same volume. It does not just do peak normalization, as many normalizers do. Instead, it does some statistical analysis to determine how loud the file actually sounds to the human ear. Also, the changes it makes are completely lossless. There is no quality lost in the change because the program adjusts the mp3 file directly, without decoding and re-encoding.

Seems like it does a very good job that will help to save my hearing when using the in-ear phones. It didn't work on all the files I had in my batch, but if I put the ones it failed on through MP3normalizer (which doesn't seem to do much on its own), MP3Gain can then normalise them after all. Quality of the sound seems fine so I think that here is a program that will stop me going mutton jeff (deaf for non-c***neys)!

If you use a real speaker system you can hear the sound quality got worse with this program. Not good.

Does what it's supposed to do. It losslessly normalizes the volume of all your mp3s. No more having to adjust the volume for each song.
It does lower the volume of most songs significantly though (for a reason) so you'll have to set your volume higher than usual.
I use foobar2000 to sutomatically reduce the volume of non-MP3gained songs by 7.5db so all songs whether MP3gained or not sound roughly the same.
