Here is a file I found with some info:

-------------------------------------------------------------------------

HEADER: (bytes 00-19)
=======
     byte #           Description
     ------           -----------
     00-12            Creative Voice File
     13               1A (eof to abort printing of file)
     14-15            1A 00  word offset in file of first data block

     18-19            2's Comp of Ver. # + 1234h (VOC-HDR puts 29 11)

DATA: (bytes 1A+)    A series of data blocks terminated by 00

   Data Block:  TYPE(1-byte), SIZE(3-bytes), INFO(0+ bytes)

*Sound info format:         *Silence info format:
 -----------------           --------------------
 00   Sample rate            00-01  Length of silence (weird encryption)
 01   Compression type       02     38
 02+  Data


Sample rate       -- SR byte = 256-(1000000/sample_rate) *** SEE BELOW ***
Length of silence -- (# of .1 seconds encrypted)
Compression type  -- 8-bits    = 0
                     4-bits    = 1
                     2.5-bits  = 2
                     2-bits    = 3
                     Multi DAC = 3+(# of channels)

Silence encoding in VOXKIT finds quiet places in file, and creates a separate
block that is of type Silence.



The only remaining mysteries are what types 2&5&8+ are if they exist, and the
exact conversion of the silence length integer to seconds.  If you have any
more information, please email me at:   galt@dsd.es.com
I hope this info will help to create more  public domain utilities for the
soundblaster.

*** (MSF) if the file is stored for a sample rate over 22222 then
	  no compression is allowed and the speed is stored as a word
	  given by

	  SR WORD= 65536-(256000000/sample_rate)
