How to Add Desktop Audio to OBS: A Comprehensive Guide

Adding desktop audio to OBS (Open Broadcaster Software) is a crucial step for streamers, content creators, and anyone looking to capture high-quality audio from their computer. Whether you’re streaming a game, recording a podcast, or creating a tutorial, ensuring that your desktop audio is properly integrated into OBS can make or break the final output. In this article, we’ll explore various methods to add desktop audio to OBS, discuss potential challenges, and provide tips to optimize your audio setup.

Understanding Desktop Audio in OBS

Before diving into the technicalities, it’s essential to understand what desktop audio refers to in the context of OBS. Desktop audio encompasses all the sounds produced by your computer, including system sounds, music, game audio, and any other audio playing through your speakers or headphones. Capturing this audio in OBS allows you to include it in your streams or recordings seamlessly.

Method 1: Using the Default Audio Capture Settings

OBS comes with built-in audio capture settings that allow you to add desktop audio with minimal configuration. Here’s how you can do it:

  1. Open OBS: Launch OBS on your computer.
  2. Navigate to Settings: Click on the “Settings” button located at the bottom-right corner of the OBS interface.
  3. Audio Settings: In the Settings window, select the “Audio” tab.
  4. Desktop Audio Device: Under the “Desktop Audio” section, select the audio device you want to capture. This could be your default system audio device or a specific output device.
  5. Apply Changes: Click “Apply” and then “OK” to save your settings.

This method is straightforward and works well for most users. However, if you encounter issues or need more control over your audio sources, you may need to explore alternative methods.

Method 2: Using Virtual Audio Cables

Virtual audio cables are software solutions that allow you to route audio between different applications and devices. They can be particularly useful if you want to separate desktop audio from other audio sources or if you’re experiencing issues with OBS’s default audio capture.

  1. Install a Virtual Audio Cable: Download and install a virtual audio cable software like VB-Cable or Voicemeeter.
  2. Configure Audio Routing: Set your system’s default audio output to the virtual audio cable.
  3. Add Audio Source in OBS: In OBS, add a new audio source and select the virtual audio cable as the input device.
  4. Adjust Audio Levels: Use the audio mixer in OBS to adjust the levels of your desktop audio.

Virtual audio cables offer greater flexibility and control, but they can be more complex to set up. They are ideal for advanced users who need to manage multiple audio sources.

Method 3: Using Audio Capture Plugins

OBS supports various plugins that can enhance its functionality, including audio capture plugins. These plugins can provide additional features and customization options for capturing desktop audio.

  1. Install an Audio Capture Plugin: Download and install an audio capture plugin like “Audio Monitor” or “Advanced Scene Switcher.”
  2. Configure the Plugin: Follow the plugin’s documentation to configure it according to your needs.
  3. Add the Plugin to OBS: In OBS, add the plugin as an audio source and configure it to capture desktop audio.
  4. Test and Adjust: Test the audio capture and make any necessary adjustments to ensure optimal performance.

Plugins can significantly enhance OBS’s capabilities, but they may require more technical knowledge to set up and use effectively.

Method 4: Using External Audio Interfaces

For users who require high-quality audio capture, external audio interfaces can be a game-changer. These devices allow you to connect professional microphones, instruments, and other audio sources directly to your computer.

  1. Connect the Audio Interface: Connect your external audio interface to your computer via USB or another compatible connection.
  2. Configure Audio Settings: In OBS, navigate to the Audio settings and select the external audio interface as the input device.
  3. Capture Desktop Audio: Use the audio interface’s software to route desktop audio to OBS.
  4. Monitor and Adjust: Monitor the audio levels in OBS and make adjustments as needed.

External audio interfaces provide superior audio quality and flexibility, but they can be expensive and may require additional setup time.

Common Challenges and Solutions

Challenge 1: Audio Delay or Sync Issues

One common issue when adding desktop audio to OBS is audio delay or sync problems. This can occur if the audio and video are not properly synchronized.

Solution: Use OBS’s audio sync offset feature to manually adjust the audio delay. You can find this option in the Advanced Audio Properties by right-clicking on the audio source in the mixer.

Challenge 2: Low Audio Quality

Low audio quality can result from incorrect settings or hardware limitations.

Solution: Ensure that your audio settings in OBS are configured correctly. Use high-quality audio devices and consider using external audio interfaces for better sound quality.

Challenge 3: Audio Not Capturing

If OBS is not capturing desktop audio, it could be due to incorrect device settings or conflicts with other software.

Solution: Double-check your audio device settings in OBS and ensure that no other software is interfering with the audio capture. Restarting OBS or your computer can also resolve this issue.

Tips for Optimizing Desktop Audio in OBS

  1. Use High-Quality Audio Sources: Invest in good-quality microphones and audio interfaces to ensure clear and professional audio.
  2. Monitor Audio Levels: Regularly monitor your audio levels in OBS to avoid clipping or distortion.
  3. Use Noise Suppression: Enable noise suppression in OBS to reduce background noise and improve audio clarity.
  4. Test Before Going Live: Always test your audio setup before starting a stream or recording to ensure everything is working correctly.

Q: Can I capture desktop audio and microphone audio separately in OBS? A: Yes, you can capture desktop audio and microphone audio separately by adding them as different audio sources in OBS. This allows you to adjust the levels independently.

Q: Why is my desktop audio not showing up in OBS? A: This could be due to incorrect audio device settings or conflicts with other software. Ensure that the correct audio device is selected in OBS and that no other applications are blocking the audio capture.

Q: Can I use OBS to capture audio from specific applications only? A: OBS does not natively support capturing audio from specific applications. However, you can use virtual audio cables or third-party software to route audio from specific applications to OBS.

Q: How do I reduce audio delay in OBS? A: You can reduce audio delay by adjusting the sync offset in OBS’s Advanced Audio Properties. Additionally, using high-quality audio devices and ensuring that your computer’s performance is optimized can help minimize delay.

Q: Is it possible to add multiple desktop audio sources in OBS? A: Yes, you can add multiple desktop audio sources in OBS by using virtual audio cables or external audio interfaces. This allows you to capture audio from different applications or devices simultaneously.

By following these methods and tips, you can effectively add desktop audio to OBS and enhance the quality of your streams and recordings. Whether you’re a beginner or an advanced user, understanding how to manage desktop audio in OBS is essential for creating professional and engaging content.
