Loopback 2.4.10

Loopback is a professional audio routing application for macOS developed by Rogue Amoeba, designed to give Mac users complete control over how audio is routed between applications and devices.



Think of it as a virtual patch bay for the audio on your Mac — without cables. With Loopback for Mac, you can create virtual audio devices that blend sound from multiple software sources and audio hardware, then send that combined output anywhere on your system.

Whether you’re a podcaster needing to combine mic input with music, a streamer sending game audio to Zoom, or a musician routing audio into a DAW, it makes it possible with flexibility and precision.

Main Features

Combine Audio Sources: Pull audio from multiple apps and physical devices into a single virtual device.

Powerful Channel Options: Add multiple output channels and customize routing visually.

Pass-Thru Device: Create simple routes between apps with minimal configuration.

System-Wide Virtual Devices: Virtual devices Loopback app creates appear in macOS as real audio sources.

Works With Any App: Route audio from apps like Music, Zoom, or DAWs like Logic/Ableton.

Works With Hardware: Include USB mics and interfaces in your virtual mixes.

Intuitive Wire-Style UI: Visual cables make creating complex setups clearer.

User Interface

Loopback’s interface is built around a visual, wire-style canvas where virtual audio devices are created and configured.

Each virtual device includes a sources column where you add applications and hardware, an output channels section, and an optional monitor. Users drag and connect elements much like in a graphics editor to define how audio flows.

Though it handles complex routing workflows, the interface stays approachable, letting beginners start with simple pass-thru devices while offering deep customization for advanced users.

FileHorse team recommends this product for anyone serious about advanced audio routing on macOS.

Installation and Setup

To install Loopback app, download the app from Rogue Amoeba’s official website and drag it from your Downloads folder into the Applications folder.

Launching it the first time prompts installation of the underlying Audio Routing Kit (ARK) and requests system permissions for routing audio, including microphone and audio access.

You must enter your administrator password to complete these steps. Once installed, the app will be ready to create virtual devices.

Uninstallation is handled from the app’s Help menu, which cleans up virtual devices and components.
