- Whats new?
- 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.
