  25.      _i_b_u_f      pointer to input sample data buffer.  The data format is short
  26.                (16-bit).  The samples are assumed to be two's complement.
  27.                Sampling rate can be either 32 kHz or 48 kHz.

  30.      _o_b_u_f      pointer to output data buffer which is a complete DIF frame.
  31.                See _d_m__d_v(_3_d_m) for more info about DIF, DV, and DVCPRO.  The
  32.                audio is inserted into the DIF frame without affecting any
  33.                video that may or may not exist in the DIF frame. The DIF
  34.                output buffer size must be either DM_DVAUDIO_NTSC_DIF_FRAMESIZE
  35.                or DM_DVAUDIO_PAL_DIF_FRAMESIZE.
