MP3Gain for Windows

MP3Gain, a tiny tool that can analyze and adjust MP3 files to ensure they have the same volume, is really useful.

The app doesn't just perform a peak normalization exercise like many normalizers. It performs a statistical analysis to determine the actual volume of the file to the human ear.

MP3Gain's changes are completely unaltered. The program adjusts the mp3 file directly without decoding or re-encoding.

Music software and portable players can adjust the metadata to determine the volume by changing the appropriate metadata.

MP3Gain is a good utility for freeware. It does what it says on the tin: equalizes MP3 volume levels. Although the interface is simple, power users may find it difficult to use.

Spanish, French and Brazilian Portuguese are supported languages.
