I’m sure you have noticed that mp3 files from differents cd sources are not on the same volumes. Sometimes you could be notice a significant volume difference between two songs.
This is the best way to resolve this problem :
The perfect program for doing this is called mp3gain
MP3Gain analyzes and adjusts mp3 files so that they have the same volume but not like other as many normalizers do, it does some statistical analysis to determine how loud the file actually sounds to the human ear. And the best are coming : all these changes are completly lossless ! No quality lost !
how to install it (on ubuntu) :
sudo apt-get install mp3gain
on terminal browse to your mp3s folder :
mp3gain -r *.mp3
that’s all ! A simple but very usefull command line.
