/* 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 */
