Loopback gives you the power of a high-end studio mixing board right inside your computer, with no wires required! Create virtual system-level audio devices on your Mac, for use in real-time by other audio applications. Take the sound from any applications or audio input devices, then send it all to another application for processing.

With Loopback's custom audio routing, you control exactly how and where audio is heard on your Mac.

### Getting Started

To begin, we recommend having a quick read-through of this manual. You can also refer back to it at any time by accessing it from the Help menu.

### Updated in Loopback 1.1.3

- Major Enhancement: Loopback's audio capture system, powered by Instant On, has been updated to improve audio capture from VMWare Fusion, FaceTime, and Flash running in Safari.

- Bug Fix: The monitoring menu now correctly shows multiple audio devices with identical names.

- Bug Fix: An incompatibility with TouchBar Macs, seen when VoiceOver was on, has been corrected. In addition, the “Add Source” popup menu now properly accepts VoiceOver presses.

- Other: Loopback now has (extremely) preliminary compatibility with MacOS 10.13 (High Sierra). While we strongly recommend users stick with a fully supported version of MacOS for now, those who are testing High Sierra will now be able to test Loopback as well.

- Other: Loopback now requires MacOS 10.10 (Yosemite) or higher.

### Recent Major Updates

- Major Enhancement: Loopback now supports nested devices, allowing one Loopback virtual audio device to be embedded inside another Loopback device. Now you can create even more powerful (and complex) setups.

- Major Enhancement: Loopback's backend, powered by Instant On, has been updated with full support for MacOS 10.12 (Sierra).

- Major Enhancement: We've made a ton of small but useful interface improvements, including tooltips for overly long device summary information, visual warnings for missing devices, a Type column in the Audio Sources table, improved window resizing and full-screen support, a popover in the Home view, and changing the “Select Application…” modal dialog into a sheet.

### System Requirements

- A Macintosh computer

- MacOS 10.10 or higher

### Installation and Removal

To install Loopback, just drag it from your download folder to the Applications folder, and launch it. Loopback will walk you through the installation it needs to run.

If you wish to remove Loopback, be sure to select "Uninstall" from the Loopback menu to properly remove any Loopback virtual audio devices from the system. Once that's done, simply drag Loopback to the Trash.

### Purchasing Loopback

We provide a free trial of Loopback for you to test. During the trial, the quality of audio passed through Loopback devices is degraded after twenty minutes. The full version of Loopback can be unlocked with a license key from our online store.
