Loopback review
A deep Mac routing tool for complex virtual devices, priced at $99 one-time.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
Loopback is a macOS application for routing audio between applications and physical devices without physical cables. It creates system-wide virtual audio devices that applications can use, making it suited to podcasters, streamers, musicians, screen-recording users, and anyone who needs to combine or redirect audio on a Mac. Its workflow covers application audio, hardware inputs, secondary monitoring devices, and configurable channel routing.
According to the vendor’s pricing information, Loopback uses a single paid plan: the Loopback License Key costs $99 USD as a one-time purchase. The license is for one user on one or more personally owned Macs and unlocks the full version. A free trial is available, with trial audio degraded after 20 minutes. The paid license makes the product a considered purchase for occasional users, while its one-time pricing may suit people who expect to keep using advanced routing features over time.
The standout capability is control over virtual-device construction. Users can combine multiple applications and physical devices, pass audio directly between applications with Pass-Thru devices, configure up to 64 channels, manually map and rewire channels, nest one Loopback device inside another, and adjust source, monitor, and device volume levels. It integrates with applications including Zoom, FaceTime, GarageBand, Logic, Ableton Live, Music, and QuickTime. Choose Loopback when Mac-only, multi-channel routing and application/device mixing are central requirements. Choose an alternative when you need Windows support or built-in audio enhancement effects rather than routing and mixing control.
