MP3 collections grow over time. You rip some CDs, record Internet radio, get some files from friends, download music from the Internet or purchase stuff in an online store. After a while you have got thousands of mp3 files from different sources and a problem. The problem is that the volume of these files does not appear to be the same. It happened before that I was constantly rising and lowering the volume when playing music on my mp3 player.
That is, until I decided to level the volume for all mp3 files and get rid of this problem. I’m performing the same operation for every new mp3 file that I add to my collection before I add it. This ensures that I can always enjoy the same volume level on all of my mp3 files.
The best program in my experience is MP3 Gain. Usage is straightforward. Select files or folders and add them to MP3 Gain. Once they have been added you click on Track Analysis. MP3 Gain analyzed all selected tracks and displays information about them in the program interface.

Once the analysis has been completed you simply click on Track Gain to level the volume of all analyzed tracks. The volume will be adjusted on all tracks. Make sure you update your mp3 collection on your mp3 player as well.

Good tip this one, v.useful software.
I’ve tried setting all my MP3s to 95dB but find that causes quite a few to have audible distortion/clipping. I tried 89dB (default) but that was just too quiet.
What setting are you using?

I’m using 92dB which is fine and I was not able to find any files coming up with distortion or clipping.
Foobar2000 does this as it plays, you can set it to track or album gain. IT does this by figuring out which is the loudest mp3 in the collection and then matches that to the whole album. there is a plugin also called Vlevel which will do it as well.
IIRC some software actually adjusts the data within the MP3 file, whereas MP3Gain only sets an overall file gain coefficient and therefore repeated changing doesn’t cause you to lose information in the original data.
I believe that’s one of the main strengths of this software versus other solutions.
