Here it is!  This is the file format information for sound files as
stored by HyperStudio, Sound Shop, Sight 'n Sound, and Browser (all
parts of the HyperStudio software/hardware package).

This file format accomodates ACE data, digitized sound, multiple
channels and lots of other goodies.  This information may be duplicated
as desired.

HyperStudio(R)   Digitized Audio File formats
	
------------------------------------------------------------
	
Audio Interchange File Format: "AIFF"  (Audio IFF)
	

	
Version: 1.1  January 21, 1988  Apple Computer, Inc.
	
Revised per File Type note: $D8, auxtype $0000  March 1989
	

	
------------------------------------------------------------
	
Adapted for SOUND SHOPtm and HyperStudio(R) use by Dave Klimas.
	

	
Version: 0.1  April 2, 1989

Version: 0.3   July 3, 1989
	

	
------------------------------------------------------------
	
NOTE:  All data is stored in Motorola 68xxx format,  ie.
	
the most significant byte is stored before the
	
least significant byte (msb - - lsb),  with the
	
following exception:
	

	
All data between 'SSDK1'-'SSND' is in 65xxx format,
	
i.e. least significant byte first (lsb - - msb).
	

	
Total header length = 96 bytes.
