Syntax
Parameter Description
Negative DAC gain (attenuation) adjustable in four 6 dB steps from 0 dB to -18 dB (0=0 dB, 3=-18 dB)
0...3
Formula to calculate the value of the 5 volume steps selectable with parameter <outStep>:
Attenuation = 20 * log (2 * outCalibrate[n] / 32768)
0...32767
Volume steps 0 - 4, each defined with outCalibrate[n]
0...[4]
Multiplication factor for the sidetone gain.
Formula to calculate how much of the original microphone signal is added to the earpiece signal:
Sidetone gain in dB = 20 * log (sideTone / 32768).
0...32767
