      aaccoder: add frequency scaling and quantization correction for PNS · b6cc8ec7
      Rostislav Pehlivanov authored
      This commit once again improves the PNS implementation by scaling the
      thresholds with frequency. The thresholds get looser as the frequency
      increases since higher frequencies are basically noise to human ears.
      
      Also, this introduces quantization error correction for PNS. Should
      the error be too much, no PNS will be used. The energy_ratio is used
      to regulate the actual encoded PNS energy: if the generated PNS
      energy is higher than the energy from the psy system, energy_ratio
      is used to correct it so that hopefully once requantized and
      transmitted the value in the decoder will be closer to what the
      encoder has.
