Function Documentation

static boolean mywrite (  void *  buf, size_t  unitbyte, int  unitnum, FILE *  fp )  [static]

Write speech data in little endian. Parameters: buf  [in] speech data unitbyte  [in] unit size in bytes unitnum  [in] number of units to be written fp  [in] file pointer Returns: TRUE on success (specified number of data has been written), FALSE on failure. Definition at line 40 of file wrwav.c. Referenced by CMN_save_to_file(), wrwav_close(), and wrwav_data().

FILE* wrwav_open (  char *  filename, int  sfreq )

Open/create a WAVE file and write header. Open or creat a new WAV file and prepare for later data writing. The frame length written here is dummy, and will be overwritten when closed by wrwav_close(). Parameters: filename  [in] file name sfreq  [in] sampling frequency of the data you are going to write Returns: the file pointer. Definition at line 73 of file wrwav.c. Referenced by record_sample_open().

boolean wrwav_data (  FILE *  fp, SP16 *  buf, int  len )

Write speech samples. Parameters: fp  [in] file descriptor buf  [in] speech data to be written len  [in] length of above Returns: actual number of written samples. Definition at line 126 of file wrwav.c. Referenced by record_sample_write().

boolean wrwav_close (  FILE *  fp  )

Close the file. The frame length in the header part is overwritten by the actual value before file close. Parameters: fp  [in] file pointer to close, previously opened by wrwav_open(). Returns: TRUE on success, FALSE on failure. Definition at line 146 of file wrwav.c. Referenced by record_sample_close().
