MP3Gain 1.4.6


What does MP3Gain do?

MP3Gain automatically adjusts mp3s so that they all have the same volume.


You mean MP3Gain normalizes mp3 files?

Yes, but MP3Gain does not use "peak amplitude" normalization as many "normalizers"
do. Audio files with very different peak amplitudes can still sound to the human
ear as though they're the same volume.
Instead, MP3Gain uses David Robinson's Replay Gain algorithm to calculate how loud
the file actually sounds to a human's ears.


Does normalizing the mp3 degrade its quality?

No. MP3Gain does not decode and re-encode the mp3 to change its volume. You can
change the volume as many times as you want, and the mp3 will sound just as good
(or just as bad!) as it did before you started.
