A very useful, free program for equalizing the volume level of your MP3 music files. Especially helpful when you want to get the same volume of compilation of songs from different albums of one or more artists. Unlike other programs of this type, MP3Gain does not correct the volume only on the basis of peak values of the signal but also performs a statistical analysis of how the volume of sound will be felt by the human ear.

Importantly, the volume changes made with the program are practically lossless. This is due to the fact that the program makes changes directly in the file, without the need to decode and re-code the file. In order to get a Polish interface, select "language files" during installation in order to install language files.

After installation, the program should start in Polish by default. In case of long file analysis time, we recommend changing the Priority Action value (in the Settings -> Advanced menu) from "Low" to "Normal".
