Soundflower

Soundflower is a MacOS system extension that allows applications to pass audio to other applications. Soundflower is easy to use, it simply presents itself as an audio device, allowing any audio application to send and receive audio with no other support needed.

A rather advanced way to use the Mac for audio is using it for active cross-over.
