I understand Soundflower to be a tool to capture computer system audio, and thus setting up as an input makes sense (or as an Aggregate Device) in Audio Midi Setup.
Q1) Why is Soundflower (2ch) an Output choice in System Preferences > Sound menu?
Q2) Why do many Soundflower tutorials recommend creating a Multi-Output Device and adding Soundflower (2ch) along side Built-in Output?
Q3) When using Soundflower, why is it even a choice to choose in a Multi-Output Device?
This make no sense to me, as I understand Soundflower to be an input only, like a microphone.
Thank you for your help!
