We have a Sun Sparcstation 1.  The chip inside that it uses for D/A
and A/D is the AM79C30 Digital Subscriber Controller.  The chip uses a
sampling rate of 8192 samples per second, with each sample being
8-bits.  The chip uses either u-law or A-law compression.  I would
like to take uncompressed digital sound samples, say generated by a
software synthesis program (computer music for example), and feed it
to this chip.

Does anybody have any code or know where I can get my hands on some
that would convert "normal" (uncompressed) 16 bit digital audio into
the 8 bit u-law (or A-law) compressed form that the AM79C30 uses?  Or
point me at some references (that I could try and puzzle over; my math
is zip)?
