I needed something to lower the volume on a large number of Mp3 files. I had trouble getting Audacity to do it - it seemed to only do some of the files in a given directory or collection. Furthermore it only was able to do edits by converting to wav files first then back to mp3 (!!!!??)
Then I tried the Sobolsoft volume program and it puffed the size of my mp3 files to almost twice the original!
So the MP3Gain was the best option by far. Not only does it not increase file sizes, it will do the edits without having to do any conversions to intermediate wave files.
At first I was confused about how to get it to lower the volume below the target of 75db. So that is the only pain - that you have to work around this limit.
How I did it:
Select 'Add folder' (note it will edit your files IN PLACE)
Change "Target 'Normal' Value" to 75 (it won't go lower)
Click 'Track Analysis' (will test all in folder - takes a while if lots of files - skip the following step if your volumes are already less than 75)
Click 'Album Gain' (should be one of the icons on top - makes all in folder 75
Click 'Modify Gain', then 'Constant Gain'
Set slider to lowest amount (on mine this was -12db)
Click the down arrow by 'Track Gain' and make it be 'Constant Gain'
Click 'Constant Gain' (changes all tracks to -12db)
Keep doing the constant gain edit until you get volumes as low as you want.
