sfcreate - create soundfile header, or change existing one
sfcreate
[ -r sampling_rate ]
[ -c num_channels ]
[ -t header_format ]
[ -i | -f ]
[ -b | -l ]
[ --force ]
file_name
If file_name doesn't exist, sfcreate creates a new file with the
specified soundfile header. If file_name already exists,
sfcreate puts a soundfile header at the beginning of the file,
overwriting whatever was there. (See WARNINGS below.) Without a
file_name argument, sfcreate just prints a help summary.
This command is mainly useful for disk-based Cmix scripts, in which
the output function expects to find a file with a soundfile header.
You can run sfcreate from within such a script by using the
system function.
- -b
-
Use big-endian sample data format.
This is the default for all file types except wav.
(Use either this or -l.)
- -c num_channels
-
Use num_channels number of channels. The default is 2.
- -f
-
Use floating-point sample data format. (Use either this or -i.)
- -i
-
Use 16-bit (short) integer sample data format. This is the default.
(Use either this or -f.)
- -l
-
Use little-endian sample data format. This is the default for
-t wav. (Use either this or -b.)
- -r sampling_rate
-
Use the sampling rate given by sampling_rate. 44100 is the default.
- -t header_format
-
Use the specified file format. The possibilities are:
- aiff
-
AIFF format
- aifc
-
AIFC format
- wav
-
Microsoft RIFF (Wav) format
- next
-
NeXT format (same as sun)
- sun
-
Sun "au'' format (same as next)
- ircam
-
IRCAM format
aiff (or aifc for floats) is the default.
- --force
-
Overwrite the header of an existing file, even if this might result
in swapped channels or corrupted sample words. You will be told if
these things have happened after they've happened. (Isn't that nice!)

John Gibson <johgibso at indiana edu>, based on the original
Cmix sfcreate, but revised to work with multiple soundfile header
types. Thanks to Bill Schottstaedt, whose sndlib sound file library
makes this possible.
