14      <para>
15This format contains sequence of complex number samples. Each complex number
16consist two parts, called In-phase and Quadrature (IQ). Both I and Q are
17represented as a 14 bit signed little endian number. I value comes first
18and Q value after that. 14 bit value is stored in 16 bit space with unused
19high bits padded with 0.
