If you’re looking for a reliable way to route audio between applications on your Mac, Loopback is ready to serve you.
Loopback is a modern, fully-featured virtual audio device tool of our own. With a robust infrastructure and full support, Loopback is the ideal tool to route audio between applications and more.
Soundflower is an open source kernel extension for MacOS, designed to create a virtual audio output device that can also act as an input. Initial development and maintenance of Soundflower was done by Cycling '74. In 2014, Cycling '74 passed stewardship of Soundflower to Rogue Amoeba, but we ultimately lacked the time and resources needed to manage the product.
At the end of 2015, Soundflower's original author Matt Ingalls picked up the baton. The project can now be found via this GitHub link.
