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.
