Nope sorry. I have no idea about audio compression beyond the basics, and I have never implemented it.
Neither do I know anything about the IIP. However if IIP is an instruction set, it will be processor dependent, so it may be the case that many architectures and cores that are ported to Tiny OS do not offer it. Check it out! Cheers!
