I've seen this app recommended here a few times. It normalizes all your mp3s, is freeware and has what seem to be good options as far as keeping entire albums at the correct (relative) levels.
I got it because it drives me crazy when I have to turn the volume up and down all the time. I know I have quiet mp3s littered throughout my collection and I'd love to have all my songs at pretty much the same volume level
However, when it analyzes my mp3s, it wants to turn them all DOWN! According to its analysis, most of my mp3s are already clipping. According to the help file, this means that my songs are breaking up at the loudest points.
“Clipping” means that when the mp3 file is decoded by your player, some of the sound samples will be too loud. The player will “clip” these samples so that they do not exceed the maximum allowable value. This clipping creates a sort of rough, “scratchy” sound during loud parts of the song.
That's complete rubbish. Sure, it's possible that some of my thousands and thousands mp3s are clipping, but HALF of them? No freaking way. I don't buy it. I've gone through a handful of those songs that it claims are peaking and there's no "scratchy" sounds at all. Below is a screenshot of the analysis. Anybody else encounter this with mp3gain? Any other suggestions of apps that do this kind of volume adjustments?
