NAME
     dmSetAudioDefaults, dmAudioFrameSize - parameters for digital-media audio

SYNOPSIS
     #include <dmedia/dmaudio.h>

     DMstatus dmSetAudioDefaults
           ( DMparams* params,
             int width,
             double rate,
             int channels )

     sizet dmAudioFrameSize( const DMparams* params )

DESCRIPTION
     dmSetAudioDefaults sets up a parameter list with all of the necessary
     parameters to describe audio for the digital-media libraries.  The
     parameters that are set and their values are:  DMMEDIUM = DMAUDIO,
     DMAUDIOWIDTH = width, DMAUDIOFORMAT = DMAUDIOTWOSCOMPLEMENT,
     DMAUDIORATE = rate, DMAUDIOCHANNELS = channels, DMAUDIOCOMPRESSION
     = DMAUDIOUNCOMPRESSED.

     dmSetAudioDefaults returns DMSUCCESS if there was enough memory
     available to set up the parameters, and DMFAILURE if not.

     dmAudioFrameSize takes an audio parameter list and returns the number of
     bytes needed to store one frame (one sample from each channel).


EXAMPLE
              DMparams* audioParams;
              if ( dmParamsCreate( &audioParams ) != DM_SUCCESS ) {
                  printf( "Out of memory.\n" );
                  exit( 1 );
              }
              if ( dmSetAudioDefaults( audioParams,
                                       16,     /* width (in bits/sample) */
                                       22050,  /* sampling rate */
                                       2       /* # channels (stereo) */
                                       ) != DM_SUCCESS ) {
                  printf( "Out of memory.\n" );
                  exit( 1 );
              }
              printf( "%d bytes per frame.\n",
                      dmAudioFrameSize( audioParams ) );
              dmParamsDestroy( audioParams );
