Loopback gives you the power of a high-end studio mixing board right inside your computer, with no physical wires required! Create virtual system-level audio devices on your Mac, for use in real-time by other audio applications.

Major Updates in Loopback 2.0.0
A Massive Interface Overhaul
The most noticeable change in Loopback 2 is its brand-new user interface. The first version of Loopback offered tremendous audio routing capability, but harnessing that power was not as simple as it could've been.For version 2, we worked hard on a redesigned interface that will be intuitive for everyone. Loopback now features a simple new wiring system that lets you easily visualize and adjust how your audio will flow.
Volume Controls Galore
Users asked for it, and we provided it. Loopback 2 provides control over volume levels at every step of the way. The volume from individual sources can be tweaked relative to other sources, to get the perfect mix. Audio levels sent to monitoring devices can also be adjusted, as can the audio level from the virtual audio device itself.More Powerful Monitoring
Monitoring virtual audio devices is now simpler than ever. Just add a monitor at the end of the device, and wire it up to get the exact audio desired. Listen in to the entire device, or use the custom wiring to monitor just part of the audio. You can even have multiple Monitors per virtual audio device, so you can hear exactly what you need to.Capture Hidden Sources
Audio can now be captured from previously unavailable sources, like Siri, VoiceOver, and Text-to-Speech. Hold down the option key while clicking the Add Source button to reveal the “Running Processes” menu, then select the correct hidden source.Much More to See
