Et værktøj der kan ændre på lydstyrken på mp3 filer direkte. Når det nu ikke kan være anderledes.

http://mp3gain.sourceforge.net

"MP3Gain analyzes mp3 files to determine how loud they sound to the human ear. It can then adjust the mp3 files so that they all have the same loudness without any quality loss. This way, you don't have to keep reaching for the volume dial on your mp3 player every time it switches to a new song."
