Loopback gives you the power of a high-end studio mixing board right inside your computer, with no wires required! Create virtual system-level audio devices on your Mac, for use in real-time by other audio applications. Take the sound from any applications or audio input devices, then send it all to another application for processing.
With Loopback's custom audio routing, you control exactly how and where audio is heard on your Mac.
