M-DAX
Compressed audio formats such as MP3, WMA (Windows Media Audio) and MPEG-4 AAC reduce the
amount of data by eliminating signal components that are hard for the human ear to hear. The “M-DAX”
function generates the signals eliminated upon compression, restoring the sound to conditions near those
of the original sound before compression. It also restores the original bass characteristics for a rich and
expanded tonal range.
