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.
