Create virtual sound devices to take sound from applications and audio input devices and then send it to an audio processing application. Loopback gives you the power of a mixing console studio, right on your computer!
Setting up a virtual sound device from multiple sources is easy. Just add the applications and physical audio devices you want to include in the audio source table.
Your Mac will show Loopback virtual devices exactly like physical devices. Find them listed among other devices in System Preferences, or select them as input or output to any audio application.
Loopback can also create pass-thru devices that send audio from one application to another. Set the Loopback device as an output in one app and an input in another to stream audio directly between apps.
