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()・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.

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.
