Hi badmelonfarmer,
We've been able to identify the Audacity issue and it's related to some funky ways that Audacity handles threads. Unfortunately the fix will involve a pretty big rewrite of a fairly central piece of code and I didn't want to hold up 64 bit support any longer for this. We're going to roll out 64 bit support to Omnipressor and SP2016, then we should be able to address this in an update down the road.
Sorry it can't be sooner,
Dan
