About Supreme

  • Technology to extrapolate and supplement with proprietary algorithm, the high-frequency range that is cut off when encoding at low bit rate.

    Supplementing is optimized by compression format (AAC, MP3, WMA or WAV) 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.
