0...3
Formula to calculate the value of the 5 volume steps selectable with parameter
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
