FINALLY, AN INTELLIGENT MP3 VOLUME NORMALIZER!

Tired of reaching for your volume knob every time your mp3 player changes
to a new song? 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 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.
