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. Lowering the volume of MP3s can actually IMPROVE sound quality since it prevents MP3 files from clipping (a phenomena that occurs with near maximum amplitude values).
With MP3Gain you can adjust your songs per file, which makes them all play at the same loudness (radio gain), or per album, which keeps the volume differences within an album but makes the albums play at similar loudness.
I run an Internet Radio station (<a href="http://www.radiocnoc.com" class="korostus" target="_blank">http://www.radiocnoc.com</a>), and all the stations MP3's are run through MP3Gain before being used.
