Even AudioHijack doesn't have access to the full mix of the system.
They can only grab the audio at the bottom of each process. Plus, the
method being used is not forward compatible as the HAL evolves. I would
not recommend going that route.

grab the sample data.
cf. Audio Hijack:

They require you to launch the application via Audio Hijack so they
can "hijack" the audio.
