This directory contains the files make up the kernel that does the actual filtering of audio samples. Most of the actual work is performed in classes defined in C++ header files. There is an Objective-C++ KernelBridge class that provides an interface that Swift can use, but it just wraps a C++ Kernel class. The key is to not leak any C++ constructs into a file that might be used by Swift.
- KernelBridge -- provides simple interface in Obj-C for the kernel. Confusingly, this is named 'Kernel.h' so that the KernelBridge package can import it.
- C++ -- the C++ header file that performs the actual sample rendering.
Note that many of the include files it uses are found in the AUv3-DSP-Headers library that comes from the
AUv3Support package.
Also note that although the KernelBridge Obj-C class is defined here, there is the
KernelBridge package that adds necessary Swift protocol conformances to it.
This split is due to the fact that the Obj-C class is unable to state that it conforms to protocols defined in
Swift.
