wxMP3gain is an easy to use volume normalizer software. It features fine tuning, with maximum detail to normalize the level of volume gain of any MP3. wxMP3gain provides ease of use with advanced options to enable an efficient standardization of a MP3 volume. Of course, wxMP3gain can process a single MP3 file or can process hundreds of files (batch normalize). wxMP3gain not only adjusts the volume level between different MP3 files, but even within the same song, produces fine adjustments, which allows you to listen your files in a new way.
