Ginger Audio has released GroundControl, a freeware zero-latency audio router and virtual audio driver for macOS.

GroundControl allows you to send audio from one application to another with zero latency. The Ground Control virtual audio drivers have 3 settings, 2 channels, 16 channels, and 64 channels.

The audio output of the GroundControl drivers can be monitored using the GroundControl Cube app, which looks like a typical monitor controller. GroundControl Cube lets you control ins/outs, mono, mute, dim, and the overall output level.

Like most monitor controllers, it has a large central knob for the output level; remember, this doesn’t affect the input level, only output. It’s pretty cool that it has a nice meter for visual feedback, too.

GroundControl is an alternative to the popular Soundflower app. Soundflower was incredibly useful and easy to use, but it didn’t keep up with changes to macOS and became virtually defunct. Blackhole became an obvious successor, but I’m not sure how well that works (if at all) anymore post-macOS Catalina.

So, here we are now with GroundControl, and if you’ve never used an audio router like this, you can think of it like virtual audio cables.

How it works, in simple terms, is that you select GroundControl as the audio output for the source application and as the audio input for the receiver application.

If you check out the website, you can see a list of applications that could benefit from GroundControl, including OBS, YouTube, Spotify, and Zoom. If you are a podcaster, streamer, or you do any form of online education, GroundControl by Ginger Audio is for you.

One of the most common uses for Soundflower in its day was to record your system sound into your DAW. In other words, it was the go-to app if you wanted to record audio from a web browser, like a YouTube video into your DAW.

With GroundControl, that’s super-easy; just set your system audio output to GroundControl 2 channel, and set the audio input/device for your DAW to GroundControl 2 channel. On the GroundControl Cube, the input should be GroundControl 2 channel, and the output is whatever you want to hear playback through; your audio interface, core audio, etc.

GroundControl is a simple app that you probably won’t realize you needed so much until you have it. Right now, it’s macOS only, but a Windows version will be available at some point.

Up to 192kHz with zero latency, and the latest M1 chip and macOS Big Sur are supported. It’s nice to be a macOS user and not be scared an update will prevent something from working for a change!
