Think of the Soundflower device as your cable. Once installed, you’ll find a couple of extra sound devices in your System Preferences: There’s a commercial product called Loopback from Rogue Amoeba, or an open source alternative called Soundflower.įollow the instructions to download and install.

On Windows you have a product called VB-Cable (the approach for Windows is similar to what’s described here). What happens though if you want to route your audio from one application to another? For example, can you pipe the audio from a Web SDR running in your browser straight into WSJT-X (or any other digital mode software)? What you need are ‘virtual audio cables’. Normally you would use a physical audio cable between your radio to your Mac, either via a soundcard interface like a Rigblaster, or even a direct USB connection to your Mac and your radio.

You’re running some digital mode software like WSJT-X on your Mac.
