Restorer
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 "Restorer"
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.
