- /* 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 */
