	(I'm sure this has been discussed within recent memory, but apparently
not within my own useful memory.)
	The SPARCstation plays audio data which has been compressed from a
12-bit range to an 8-bit range, using a (presumably) nonlinear mapping
for better signal-to-noise ratio at low amplitudes.  Where can I find
out just what this mapping is?  The subject is glossed over lightly in
the Sun documentation.
	Thanks,
		Vance
