Beginning with Mac OS X 10.7, AudioComponents can be registered and used directly without
involving the Component Manager. The system scans certain directories for bundles with names
ending in “.audiocomp” or “.component” (the latter permits registering plug-ins in a single
bundle with both the Component Manager and the Audio Component system). These directories
are scanned non-recursively:
~/Library/Audio/Plug-Ins/Components
/Library/Audio/Plug-Ins/Components
/System/Library/Components
