How to Capture Desktop Audio with Streamlabs OBS on Mac

Streamlabs OBS is a versatile tool for any content creator looking to integrate high-quality audio into their live streams or recordings. Here’s how to set it up to capture your desktop audio effectively.

Step 1: Install Virtual Audio Cable

For Mac users, capturing desktop audio may require an additional tool. Installing software like BlackHole or Loopback allows you to create a virtual audio device: 1. Download and install a virtual audio cable. 2. Set the virtual device as the output device in your Mac's audio settings. 3. Configure Streamlabs OBS to capture this virtual audio device.

Step 2: Adjust Audio Settings in Streamlabs OBS

After setting up your virtual audio cable, follow these steps: - Open Streamlabs OBS. - Go to the 'Settings' menu and select 'Audio'. - In the 'Global Audio Devices' section, set the desktop audio to the virtual cable you just created. This ensures Streamlabs OBS captures sound coming from all applications on your desktop.

Step 3: Test Your Setup

Before going live, do a quick test: - Start a recording session. - Play audio from any application (like iTunes or YouTube) to check if Streamlabs OBS picks it up. If you hear the sound in your recording but not in your headphones, review your audio routing settings.

Common Issues and Fixes

If you encounter problems while capturing audio, consider these troubleshooting steps: - Ensure the virtual audio cable is selected as your primary output device in System Preferences. - Check that you have allowed Streamlabs OBS the necessary audio permissions in your Mac's privacy settings. - Restart both your Mac and Streamlabs OBS to refresh settings.
