• SUPREME:
Technology to extrapolate and supplement with
proprietary algorithm, the high-frequency range that is
cut off when encoding at low bit rate (less than 128Kbps,
Sampling frequency is 44.1kHz).
Supplementing is optimized by compression format
(MP3, WMA and AAC) and processed according to bit
rate. The effect is negligible with music that is encoded
at high bit rate, variable bit rate or has minimal high
frequency range.
