6.5.2 Audio programming model
The audio programming model shows how the signal path can be influenced by varying the
AT command parameters. The model is the same for all three interfaces, except for the
parameters <outBbcGain> and <inBbcGain> which cannot be modified on the digital audio
interface is being used, since in this case the DAC is switched off.

parameters are adjusted with AT^SNFO.
