How to Install Virtual Sound Card on Mac for Screen Recorder Utility

Are you looking for a way to capture system audio on your Mac? One of the most effective ways to achieve this is by installing a virtual sound card or driver. In this article, we will walk you through the steps to install a virtual sound card on your Mac and configure it to use with WSJT-X.

Why Do You Need a Virtual Sound Card?

In order to capture system audio on your Mac, you will need to install a virtual sound card or driver. This is because your Mac does not have the ability to capture system audio by default. A virtual sound card allows you to create composite audio devices using the Audio MIDI Setup app.

How to Install Virtual Sound Card

There are several options available for installing virtual sound cards on your Mac. One popular option is Soundflower, a commercial product that provides a simple and easy-to-use interface for creating virtual audio cables. Another open source alternative is Loopback from Rogue Amoeba.

Once installed, you will find a couple of extra sound devices in your System Preferences. You can then configure the output to be Soundflower, which will allow you to direct the sound output from one app into the input of another.

How to Configure Virtual Sound Card with WSJT-X

To configure your virtual sound card with WSJT-X, follow these steps:

1. Start up WSJT-X and go to Preferences, Audio.

2. Select the Output to be Soundflower.

3. Instead of configuring Speakers for output and Mic for input, select Soundflower as the input for one app and the output for another app.

How Virtual Audio Cables Work

Think of a virtual audio cable like a physical audio cable between your radio and your Mac. With a virtual audio cable, you can pipe the audio from one application to another, such as routing the audio from a Web SDR running in your browser straight into WSJT-X.

In this article, we have shown you how to install a virtual sound card on your Mac and configure it to use with WSJT-X. With a virtual sound card, you can capture system audio on your Mac and route it to other applications like WSJT-X. Whether you are using a commercial product like Soundflower or an open source alternative like Loopback, the process is relatively straightforward.
