mp3gain: MP3Gain (Mp3 Analyzes and Adjusts)
mp3gain:
mp3gain: MP3Gain does not just do peak  normalization, as many  normalizers do
mp3gain: Instead, it does some statistical analysis to determine how  loud the
mp3gain: file  actually  sounds  to  the  human ear. Also, the changes MP3Gain
mp3gain: makes are completely lossless. There is no quality lost in the change
mp3gain: because the program  adjusts  the mp3 file directly, without decoding
mp3gain: and re-encoding.
