That's not very difficult. You have to convert the .au files to .snd files
with the appended program. Then use the program VOC-HDR.EXE from your
SB distribution disk to add the right header to the .snd file. Now you
get a .voc file, which can be played by VOUT.EXE (also on your SB disk).

Here is the program to convert .au files to .snd files (I hope that helps):

OK, here it is.... Converts Sun uLAW files (8khz sample rate) to
8 bit sound samples (.SND).
