There’s a basic 2-channel device for stereo streams, and two multi-channel variants with 16 and 64 channels. GroundControl adds three virtual audio devices to your macOS Audio/MIDI Setup. It also works on the latest Macs, including the M1 processor and macOS Big Sur. According to the developer, GroundControl has zero latency and provides up to 64 channels at sample rates up to 192 kHz. With GroundControl, Ginger Audio has just released a free alternative that’s designed to easily pass audio from one app to another. On the Mac, Soundflower was a widely used solution until it fell into disrepair. And there are many situations that require you to send the audio output of one application to another, like streaming, recording on-screen video, recording stuff from the web, using multiple DAWs and more. Routing audio streams between applications on your computer should be a simple task, but in reality, it’s often trickier than it sounds. You can specify the cable count for each virtual driver and give it a recognizable name.
In the latest version, GroundControl Cube now lets you create your own virtual audio drivers for use in other software like DAWs or stand-alone software synths. And it’s free! Update: GroundControl Cube 2.0 released GroundControl makes it easy to send multi-channel audio streams from one application to another with zero latency, picking up where Soundflower left off.
Ginger Audio has released GroundControl Cube v2.0, a virtual audio device for macOS.
