Is there a list of component types somewhere? My app is not so much an
effect as it is an analyzer. Should I still be using 'aufx'?

In the CoreAudio SDK have a look at the SampleEffectUnit - that
creates a
simple AU (of type aufx as Philippe described) and you can then
install the
bundle in (/ or ~/) Library/Audio/Plug Ins/Components - then it will be
found by the validator using:
auval -s aufx

tech note 2091 says to do this:
Component comp;
ComponentDescription desc;
desc.componentType = kAudioUnitType_Output;
desc.componentSubType = kAudioUnitSubType_HALOutput;
desc.componentManufacturer = kAudioUnitManufacturer_Apple;
desc.componentFlags = 0;
desc.componentFlagsMask = 0;
comp = FindNextComponent(NULL, &desc);
if (comp == NULL) exit (-1);
OpenAComponent(comp, &InputUnit);
This grabs the Apple: AudioDeviceOutput component, but if I am trying
to list my own AU in the AUValidation, I assume I need to make my own
component? I don't see anything anywhere about making new components.
For that matter, an Xcode search of all frameworks for the
"FindNextComponent" or "OpenAComponent" functions returns nothing.
I think if I can figure out how to test my AU in the AUValidator, I
will be better able to resolve some of these questions about how AUs
work.
I've poked around in some of the AU examples in "/Developer/Examples",
but sweet christ some of those projects are over 10,000 lines of code,
surely there must be some less complex examples?
