normalize the volume of your MP3 files MP3Gain analyzes and adjusts mp3 files so that they have the same, consistent volume. The program does not just do peak normalization, as many normalizers do, but instead attempts statistical analysis to determine how loud the file actually sounds to the human ear. 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. Copyright

Still the best after all these years... 5 stars by mikesantana Dec 09, 2015 (Read all my 25 reviews)
First used this when I was on Win ME, now on Win 10! Works ONLY on MP3s, because what it actually does is change media playback settings in the MP3 file headers. It does NOT touch the actual music content at all. So it can always return to the initial default with no harm done. Its main use (and what I want) is to make any motley collection of music tracks all sound about the same loudness to the human ear. Once it has analyzed the tracks, it records the current (default) settings in the file headers, and lists them - this never needs to be done again. It tells you whether that level "clips" the sound peaks (happens a lot on old recordings), and whether the target normalized level will "clip". So you can choose a target level which will preserve the sound quality of all tracks (no clipping), let some clip (will cause odd distortion), or set it to keep peaky tracks below clip level - I choose this usually, choosing a target level so that few if any tracks will be affected. All this is easy to discover from the display, with a little trial-and-error. So my car's MP3 player collection currently includes music from Free, Queen, B.B. King, Everly's, Motorhead, Abba, Cream, Buddy Holly, Santana, Pink Floyd, Miles Davis and Mozart - among others! All very listenable... Much easier to use than it sounds - try it! show Review details
Consider it done 5 stars by gimpguy Jul 27, 2012 (Read all my 1159 reviews)
Mp3Gain did a wonderful job on some radio tunes I have recorded and now they all sound great. Some had up and down loudness, etc... and this actually equalized them and you can't even tell now. If there are other distortions or such that this won't fix, just use Audacity. The two combined create a powerful music fix. Great work. show Review details
