  15 /* NICAM 728 32-kHz, 14-bit digital stereo audio is transmitted in 1ms frames
  16    containing 8 bits frame sync, 5 bits control, 11 bits additional data, and
  17    704 bits audio data.  The bit rate is reduced by transmitting only 10 bits
  18    plus parity of each 14 bit sample, the largest sample in a frame determines
  19    which 10 bits are transmitted.  The parity bits for audio samples also
  20    specify the scaling factor used for that channel during that frame.  The
  21    companeded audio data is interleaved to reduce the influence of dropouts
  22    and the whole frame except for sync bits is scrambled for spectrum shaping.
  23    Data is modulated using QPSK, at below following subcarrier freqs */
