Apple claims to be working on a compression schemes that go up to 6X.  
If anyone knows how to achieve that kind of compression, please email
or followup.

Fibonacci delta (at least as done in IFF 8SVX compressed sample files) 
achieves 2X, while adding distortion.  (The NewTek demo reel 1 used it 
throughout yet it was listenable.)

I get rid of strings of zeros by editing them out with Audiomaster.  If
two sounds need to be played with some silence in-between, play two sounds
with a timer wait in the middle.
