23  containing 8 bits frame sync, 5 bits control, 11 bits additional data, and
24  704 bits audio data. The bit rate is reduced by transmitting only 10 bits
25  plus parity of each 14 bit sample, the largest sample in a frame determines
26  which 10 bits are transmitted. The parity bits for audio samples also
27  specify the scaling factor used for that channel during that frame. The
28  companeded audio data is interleaved to reduce the influence of dropouts
29  and the whole frame except for sync bits is scrambled for spectrum shaping.
30  Data is modulated using QPSK, at below following subcarrier freqs */
