Supreme Setting
When AAC, MP3 or WMA files encoded at a low bit
rate (less than 96kbps (fs= 44.1k, 48kHz)) are played,
this function restores their high frequency region
to approach the sound quality of equivalents of
these files encoded at a high bit rate. Processing is
optimized for the compression format used (AAC,
MP3, or WMA), and adjustment is made for the bit
rate used.

"Supreme : ON" Plays sound using the Supreme function.
"Supreme : OFF" Plays the original sound stored in the audio file.
