128c2ecf20Sopenharmony_ciDescription
138c2ecf20Sopenharmony_ci===========
148c2ecf20Sopenharmony_ci
158c2ecf20Sopenharmony_ciThis format contains sequence of complex number samples. Each complex
168c2ecf20Sopenharmony_cinumber consist two parts, called In-phase and Quadrature (IQ). Both I
178c2ecf20Sopenharmony_ciand Q are represented as a 14 bit signed little endian number. I value
188c2ecf20Sopenharmony_cicomes first and Q value after that. 14 bit value is stored in 16 bit
198c2ecf20Sopenharmony_cispace with unused high bits padded with 0.
208c2ecf20Sopenharmony_ci
218c2ecf20Sopenharmony_ci**Byte Order.**
228c2ecf20Sopenharmony_ciEach cell is one byte.
