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