Enumerate and Extract Audio Buffers When Debugging C++ Applications
We show a method to add introspection capabilities to any C++ application by combining DWARF debug information with simulated execution. For example, we simulate execution of the begin() and end() methods of C++ containers to enumerate all elements of a container. Applying this method recursively to all local and global variables allows us to iterate over all C++ objects in a live process or core dump. Combining this with user-provided information about which types own audio buffers and how the samples are encoded allows us extraction of audio buffers.
