NAME
     dmDVAudioEncode - implements DV and DVCPRO audio encode

SYNOPSIS
     #include <dmedia/dm_audioutil.h>

     DMstatus dmDVAudioEncode(DMDVaudioencoder handle,
			  void *ibuf, void *obuf, int *nsamples)

PARAMETER
     handle    DMDVaudioencoder structure, created by
	       dmDVAudioEncoderCreate(3dm), specifies the states of the signal
	       processing parameters.

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

     obuf      pointer to output data buffer which is a complete DIF frame.
	       See dm_dv(3dm) for more info about DIF, DV, and DVCPRO.	The
	       audio is inserted into the DIF frame without affecting any
	       video that may or may not exist in the DIF frame. The DIF
	       output buffer size must be either DM_DVAUDIO_NTSC_DIF_FRAMESIZE
	       or DM_DVAUDIO_PAL_DIF_FRAMESIZE.

     nsamples  number of samples to be processed.  Returns the number of
	       samples actually encoded.

RETURNED VALUE
     Returns DM_FAILURE or DM_SUCCESS.

DESCRIPTION
     dmDVAudioEncode(3dm) implements DV and DVCPRO audio compression.
