Parameters

  • boost is a value between 0 and 65535.
    • Treble boost can be set from -12 to +10.5 dB boost (in 1.5 dB steps) at and above frequencies ranging from 1000 to 15000 Hz (in 1000 Hz steps).
    • Bass boost can be set from 0 to 15 dB boost (in 1 dB steps) below frequencies ranging from 20 to 150 Hz (in 10 Hz steps).
    • To calculate the value for boost:
      • treble boost = ((treble amplitude/1.5 + 8) * 16) + treble frequency/1000
      • bass boost = ((bass amplitude * 16) + (bass frequency/10)
      • boost = treble boost * 256 + bass boost
    • A boost value of 0 will turn off the audio enhancement.
