It supports AAC (mp4/m4a/QuickTime) audio files in addtion to mp3 files. If you are not familiar with mp3gain, stop reading this, and go to http://mp3gain.sourceforge.net. AACGain normalizes the volume of digital music files using the ReplayGain algorithm. It works by modifying the global_gain fields in the mp4 samples. Free-form metadata tags are added to the file to save undo information, making the normalization process reversable. AACGain uses the same command-line user interface as mp3gain. </longdescription> </pkgmetadata>
