It supports AAC ([[mp4]]/[[m4a]]/[[QuickTime]]) audio files in addition to mp3 files. Aacgain normalizes the volume of digital music files using the Replay Gain algorithm. It works by modifying the global_gain fields in the aac samples. Free-form metadata tags are added to the file to save undo information, making the normalization process reversible.<br /> <br /> aacgain uses the same command-line user interface as mp3gain, and is compatible with the mp3gain Visual Basic GUI.</div>
