1362306a36Sopenharmony_ci===========
1462306a36Sopenharmony_ci
1562306a36Sopenharmony_ciThis format contains sequence of complex number samples. Each complex
1662306a36Sopenharmony_cinumber consist two parts, called In-phase and Quadrature (IQ). Both I
1762306a36Sopenharmony_ciand Q are represented as a 14 bit signed little endian number. I value
1862306a36Sopenharmony_cicomes first and Q value after that. 14 bit value is stored in 16 bit
1962306a36Sopenharmony_cispace with unused high bits padded with 0.

2162306a36Sopenharmony_ci**Byte Order.**
2262306a36Sopenharmony_ciEach cell is one byte.
