MP3Gain is an open source cross-platform audio normalizer which analyzes and adjusts MP3 files so that they have the same perceived volume. MP3Gain does not simply look at the peak volume and adjust the file accordingly, but does statistical analysis to determine how loud the file actually sounds to the human ear. The changes MP3Gain makes are lossless, as the program adjusts the mp3 file directly, without decoding and re-encoding. It does this by changing the scale factor for each MP3 frame. Recent versions of MP3Gain can also use metadata to store information on perceived volume or volume adjustments.
A comment on the open discussion page of the official website suggests that further development of the project may have been abandoned in 2005.[citation needed]
