Thanks very much!

We are encoding gigabytes of mono speech - using multiple cores could 
cut quite a lot of time off our asset builds.

tbh, it wouldn't be that much work to change our audio compiler so it 
runs 2 compiles at the same time, but it would save doing the work if 
the encode dll took care of all that.

..of course, the audio compiler would need modifying _again_ for a quad 
core machine - we need a new paradigm, dammit!
