Soundflower

Subject: Soundflower Purpose: To explain what Soundflower is, its primary use cases, installation considerations, and basic operational guidance. 1. Introduction Soundflower is a free, open-source kernel extension (kext) for macOS that enables internal audio routing. In essence, it creates virtual audio input and output devices, allowing audio to be passed between different applications on the same computer. Think of it as a software "patch cable" or an internal audio mixer.

If you are running macOS 10.14 or older, Soundflower can be helpful. If you are running macOS 10.15 or newer, use BlackHole instead for the same functionality without compromising system security. soundflower
