+MP3Gain analyzes and adjusts mp3 files so that they have the same volume.
+MP3Gain 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 MP3Gain 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.
