I don't think these 3 methods are actually independent of each other.
For instance, AudioHijack uses Soundflower, which is a CoreAudio KEXT.
Also, I don't think there is a way other than installing your own KEXT
to capture audio either from a specific application or the entire
system unless the app that you're trying to capture provides a way to
do this (stream to file feature, etc).
