hello,

i am trying to find out what the specifics of the header is for the au sound file format. i know it has components made up of sampling rate, number of channels, etc. but i would like to have specifics. i have raw input datat that i'd like to convert to a sound file by adding the appropriate header but need header specifics in order to do so.

On a Sun, you can do a "man 3 audio_hdr" to find the following info…

AUDIO_HDR(3)              Audio Library              AUDIO_HDR(3)

header is defined in <multimedia/audio_hdr.h> as follows:
     typedef struct {
          unsigned  sample_rate;        /* samples per second */
          unsigned  samples_per_unit;   /* samples per unit */
          unsigned  bytes_per_unit;          /* bytes per sample unit */
          unsigned  channels;      /* # of interleaved channels */
          unsigned  encoding;      /* data encoding format */
          unsigned  data_size;          /* length of data (advisory) */
     } Audio_hdr;
