Hello.

I have a set of data which is mu-compressed from
12 bits to 8 bits.  I need to maniulate it in
its 12-bit form and I'm not sure what the
conversion process between the two is.  All of
the books I've looked in for an explanation have
a few graphs displaying the wonderful properties
of mu-encoding but no direct explanation of how to
go from one to another.

Does anyone out there know the definitions of the 
encoding algorithm and wish to tell me what it is?
If it makes a difference, this data was taken off 
of the audio port of a Sun Sparcstation (/dev/audio).

Thanks.
