Loopback makes it easy to pass audio between applications on your Mac. Create virtual audio devices to take the sound from applications and audio input devices, then send it to audio processing applications. Loopback gives you the power of a high-end studio mixing board, right inside your computer!
- Play Audio to All Your Podcast Guests – Combine your mic with audio sources like iTunes or QuickTime Player, then select your Loopback device as your source in Skype. Presto! Your guests all hear both your voice and your audio add-ons.
- Record Gameplay Videos – Making gameplay videos with great audio can often be very difficult. If you’re using a device like Elgato’s Game Capture hardware and you want to record both your microphone and the game’s audio at once, Loopback can assist!
- Combine Hardware Devices – Apps like GarageBand, Logic, and Ableton Live only record from a single audio device at once. Thankfully, they offer recording from many channels. With Loopback, you can combine multiple input devices into one virtual device for easy recording.
- Create Top-Notch Screencasts – Screen recorders, including QuickTime Player, allow you to include your mic’s audio. Some allow recording of system audio instead, but neither option is ideal. Create a virtual device that grabs just the mic and the app’s audio to get exactly the audio you want.
- Route Audio For Broadcasts – Set a simple (pass-thru) device as the output at the end of an Audio Hijack chain, and then as the input source in Nicecast. Now listeners can tune in to a live stream of your podcast as you record it!
- Combine Audio Sources – Configuring a virtual audio device from multiple sources is easy. Just add the applications and physical audio devices you want to include to the Audio Sources table to get started.
- Available System-Wide – Your Mac will show Loopback’s virtual devices exactly like physical devices. Find them listed among other devices in System Preferences or select them as an input or output in any audio app.
- Send Audio Between Apps – Loopback can also create pass-thru devices, which send audio from one app to another. Set the Loopback device as the output in one app and the input in another to make audio flow directly between the applications.
- Works With Any Application – Make a virtual audio device with audio from the applications on your Mac, including production apps like Logic or Reason, as well as simple audio players, like iTunes or QuickTime.
- Works With Any Input Device – Pull audio from the physical audio devices connected to your Mac. Whether you’ve got simple USB microphones, or high-end studio mixers, Loopback can access it all.
- Combine Apps and Physical Devices – Of course, you can create a virtual audio device that includes audio from both apps and physical audio devices.
- Multichannel Audio – Your virtual audio devices can be configured to have up to 32 channels, providing tremendous power.
- Custom Channel Mapping – By default, Loopback sets up channel mapping automatically. If you want to manually configure things, though, you’ve got powerful options!
- Nested Devices – You can now nest one Loopback device inside another, allowing for easier configuration, as well as even more power and control.
- Loopback now offers support for Dark Mode on MacOS 10.14 (Mojave) and up, with a new Dark theme. Loopback will automatically match the system appearance, but can also be set to either Light or Dark mode manually.
- Loopback's tracking of physical audio devices has been overhauled and dramatically improved. It will now better handle issues caused by many USB audio devices. Loopback will automatically track devices across restarts and between ports on your computer, so fewer adjustments are necessary.
- Loopback now has preliminary compatibility with MacOS 10.15 (Catalina).
- The backend Audio Capture Engine (ACE) has been updated to 11.0.0, with preliminary MacOS 10.15 (Catalina) compatibility as well as other fixes and improvements.
- Level meters have been optimized to use substantially less CPU. They've also been smartened up, to better reflect reality in certain tricky configurations.
- Loopback is now better at alerting you when physical audio devices have gone missing from your Mac.
- Several interface refinements have been made. It is now much clearer when a device and block is disabled, selected items have been given a better appearance, and new devices automatically allow you to edit their names.
- Loopback's wizard for installing, updating, and removing ACE (among other tasks) has been overhauled, with many small improvements and enhancements. Update notes are now presented on the first launch of a new version, and the wizard will now intelligently warn if uninstalling will impact other applications.
- Loopback now compensates for devices that are slow to start, so monitors don't miss audio at initial start-up.
- Loopback has been made much more resilient to breakage and corruption, often caused by cleaner utilities.
- Loopback now requires MacOS 10.12 (Sierra) or higher. If you're still on 10.11 (or lower), be sure to see our Legacy page.
- New Loopback devices now default to the same sample rate as the default system output, rather than always using 44.1 kHz.
- A new hidden preference, “ACE: Prioritize reliability over latency”, has been added. Though most users won't need this, the preference provides extra time for complex setups to process audio, at a cost of increased end-to-end latency.
- Loopback's Help menu now includes a useful new Release Notes window, so you can see changes across all versions from right inside the app.
- The look of messages displayed by Loopback has been modernized.
- Loopback's help manual has been improved and streamlined.
- The About box has been updated to provide additional version information in an easy-to-read fashion.
- Numerous other minor improvements and refinements have been made as well.
