12.1 Sound file format
Ircam sound file (.sf) are supported.
Usual AIFF and AIFF-C 16-bits sound files not compressed are also supported.
Files with
other formats
can be examined provided that that the correct
"Default Raw Sound File Format"
is set. A sound file format is defined by the following keywords and corresponding values:
type short/float
rate 'value, e.g. 44100'
byteorder big/little
channels 'number, e.g. 1'
dataoffset 'number of bytes from begining of file to begining of sample data'
The default format is
type short
rate 44100
byteorder 'the byte order of the host'
channels 1
dataoffset 0
The default format can be changed by using the "Raw format default " menu item
in the "Context" menu.
Formats can also be specified by giving them in an ascii file
as above (with any separator between the different items)
and giving that file name after the -fileFormat argument on the command line.
Example:
xspect -fileFormat myFormat soundFile.raw
where the file myFormat contains for instance:
type float
rate 44100
byteorder big
channels 1
dataoffset 'size of my header in bytes'
