Andreas Eversberg 46fa72894e C-Netz: Calibration/fix processing of tone levels on TX and RX side 
FSK and compander levels are adjusted.

Eliminate offsets between subsequent speech chunks. This is done by
high-pass filter. An offset is not passed to the filter.

Do correct audio processing chain:
 time compress -> compressor -> scrambler / pre-emphasis -> TX
 RX -> de-scrambler / de-emphasis -> expander -> time expand
