Error occurred while calculating annotation data.
Log Message:	Working audio output by Daniel Sumorok. Not quite the way I wanted to do it but it will do for now. (on a real Mac, the real audio hardware should be able to pull/grab the data from our buffers - an extra thread with its own set of buffers is wasteful!)
