Description of SPARC soundfile format?

[Greg Sandell]

Does anybody know the file format for soundfiles on the SPARC?  I checked
all three of the following, and none of them had this information:

	SUN OS manual, chapt. 5, FILE FORMATS
	SUN OS manual, chapt. 4, DEVICES AND NETWORKING
	SPARCstation 1 SunOS 4.0.3 Sun 4-C RElease notes,
		section 5.18, "SPARCstation 1 Audio Demonstration
		Program"

They are clearly non-ascii files (as an examination of the sample file
'sample.au' reveals), but are the values long floats, or what?

Sorry if this has been discussed in this group previously.

Thanks in advance,
Greg Sandell
