Normalise Volume of Quiet mp3 Files

Got some quiet mp3 files? These can be easily fixed with the normalize-audio package in Ubunutu. Install with:

sudo apt-get install normalize-audio

then run as:

normalize-audio -v myfile.mp3

where the -v just gives some verbose output.

If you have several files you want to normalise to the same level use the --mix switch; this will adjust quiet files more than average files. To apply the same amount of volume correction to several files use the --batch switch. E.g.:

normalize-audio -v --mix *MyAlbum*.mp3
