Sorry, that's not really feasible. I wasn't citing Ardour as a sensible place to find example code - it's a huge program. I was just citing as proof that using AU's in a command-line GUI-less application works fine.
If you really want to look, libs/ardour/audio_unit.cc is where 99% of our interaction with the DSP side of an AU plugin happens, but I still don't think you'll find it easy to locate the stuff you want.
