TION AND IMAGE ENHANCEMENT 4HESE ALGORITHMS CAN BE USED TO
COMPENSATE FOR REALWORLD LIMITATIONS OF SPEAKERS AMPLIl ERS AND
LISTENING ENVIRONMENTS RESULTING IN A DRAMATIC IMPROVEMENT OF
PERCEIVED AUDIO QUALITY
4HE SIGNAL PROCESSING USED IN THE !$ IS COMPARABLE TO THAT
FOUND IN HIGHEND STUDIO EQUIPMENT -OST OF THE PROCESSING IS
DONE IN FULL BIT DOUBLEPRECISION MODE RESULTING IN VERY GOOD
LOWLEVEL SIGNAL PERFORMANCE AND THE ABSENCE OF LIMIT CYCLES OR
