- 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,
