ATC sounds, random access?

	I need to record, compress and playback huge sounds (>55M) with random  
access into the sounds.  I know that NeXT's ATC uses frames which represent  
ATC_FRAME_SIZE (256) samples each, but I don't know enough about ATC to know  
if I can uncompress frames individually or if each frame uses information from  
the previous frame.  

	Any pointers to articles about ATC would be greatly appreciated also.
	If I can't uncompress frames individually I'll need to break each  
sound into chunks which would then be compressed.  Even if I can uncompress  
frames individually I'll need to set up an index structure so I can get to any  
frame quickly without having to jump from frame to frame.  The format  
specifies that each frame says how large it is, giving a pointer to the next  
frame.  

	It would be easier to use ATC as it is, so I hope the answer is yes.

Thanks,

Monty
