[LAU] Trouble using BinauralDecoder from iempluginsuite

[Iain Mott]

Please ignore, I did manage to compile the iempluginsuite and get the 
standalone running, albeit with an inversion of the y-axis since my last 
test with VST version in Ardour. Other problems too but I'll start 
asking on the SuperCollider forum first.
