関数

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

Write speech data in little endian. 引数: buf  [in] speech data unitbyte  [in] unit size in bytes unitnum  [in] number of units to be written fp  [in] file pointer 戻り値: TRUE on success (specified number of data has been written), FALSE on failure. wrwav.c の 40 行で定義されています。 参照元 CMN_save_to_file(), wrwav_close(), と 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(). 引数: filename  [in] file name sfreq  [in] sampling frequency of the data you are going to write 戻り値: the file pointer. wrwav.c の 73 行で定義されています。 参照元 record_sample_open().

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

Write speech samples. 引数: fp  [in] file descriptor buf  [in] speech data to be written len  [in] length of above 戻り値: actual number of written samples. wrwav.c の 126 行で定義されています。 参照元 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. 引数: fp  [in] file pointer to close, previously opened by wrwav_open(). 戻り値: TRUE on success, FALSE on failure. wrwav.c の 146 行で定義されています。 参照元 record_sample_close().
