+ 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 */
