 controls the microphone path amplification. Read and write options of this command refer to the active

audio mode. The write command works only in audio modes 2 to 6. 

ADC gain adjustable in eight 6 dB steps from 0 dB to 42 dB (0=0dB, 7=42dB, 8 steps of 6 dB).
0...7

Multiplication factor for input samples. Formula to calculate the negative gain (attenuation) of the input signal:

Gain in dB = 20 * log (inCalibrate / 32768)
0...32767

• The range of 

 is up to 65535 but will be suppressed to 32767. Values above 

= 65535 will cause a failure.
