obs how to record game audio only: Delving into the Nuances of Audio Capture for Gamers

When it comes to streaming or recording gameplay, ensuring that only the game audio is captured can be a delicate task. While OBS (Open Broadcaster Software) is a powerful and versatile tool for content creators, mastering its audio settings requires a nuanced understanding. This guide explores the intricacies of configuring OBS to record game audio exclusively, discussing various scenarios, tips, and troubleshooting steps to help you achieve a pristine audio recording.

Understanding the Basics of OBS Audio Configuration

OBS provides extensive audio options, allowing users to manage multiple audio sources such as microphones, system sounds, and specific application audio. To record game audio only, you’ll need to focus on separating and isolating the game’s audio from other potential sound sources.

Step-by-Step Guide to Recording Game Audio Only

1. Install and Configure OBS: Begin by installing the latest version of OBS Studio. Once installed, launch the software and navigate to the ‘Settings’ menu.

2. Set Up Audio Devices: Under the ‘Audio’ tab, configure your audio devices. Ensure that your default microphone (if needed) and default speakers or headphones are correctly selected.

3. Create Audio Sources: In the main OBS interface, click on the ‘+’ button under ‘Sources’ to add a new source. Select ‘Audio Input Capture’ if you want to include your microphone and ‘Audio Output Capture’ for capturing system sounds. However, for recording game audio only, focus on the latter.

4. Configure Audio Output Capture:

   • Add an ‘Audio Output Capture’ source.
   • Name it appropriately, such as ‘Game Audio’.
   • In the ‘Properties’ window, select the correct audio device (typically your primary sound device).
   • Crucially, under ‘Mode’, choose ‘Capture specific application audio (Windows-only)’. This option allows you to select which application’s audio should be captured.

5. Select the Game Application:

   • Click on the dropdown menu next to ‘Application’.
   • Select your game from the list of running applications. If your game isn’t listed, ensure it’s running and that its audio output is set to your primary sound device.

6. Adjust Audio Mixing (Optional): If you’ve also set up a microphone or other audio sources, you may want to adjust the mix in the ‘Mixer’ section of OBS. Mute or adjust the volume of any sources you don’t want to be recorded.

7. Start Recording: With your audio sources configured, click on the ‘Start Recording’ button to begin capturing your gameplay audio.

Advanced Tips and Troubleshooting

• Virtual Audio Cables: For more complex setups, consider using virtual audio cables (VACs) like Voicemeeter or VB-Audio Cable. These tools allow you to create virtual audio devices, enabling you to route specific audio streams to different outputs. This can be particularly useful if your game’s audio isn’t directly selectable in OBS’s ‘Capture specific application audio’ feature.

• Exclusive Mode: In Windows, setting your audio device to exclusive mode can prevent other applications from using the same device, reducing the potential for audio interference. However, be cautious with this setting as it may affect other applications’ functionality.

• Monitoring and Latency: Always monitor your audio levels and check for latency issues. Use headphones to listen to the game audio directly from OBS’s preview window to ensure everything sounds as expected.

• Software Compatibility: Some games may use custom audio outputs or have compatibility issues with OBS. In such cases, refer to the game’s forums or support documentation for potential workarounds.

Scenario-Based Considerations

• Streaming and Recording Simultaneously: If you’re streaming and recording simultaneously, ensure that your audio settings are consistent across both outputs. OBS allows you to configure separate audio tracks for streaming and recording, providing flexibility in post-production.

• Multi-Monitor Setups: With multi-monitor configurations, ensure your game is running on the primary monitor associated with your primary sound device. This can sometimes affect audio capture, especially with applications that are sensitive to monitor configurations.

• Gaming on Multiple Platforms: Gaming on different platforms (e.g., PC, console) introduces additional considerations. For console gaming, you’ll likely need a capture card that supports audio passthrough. Ensure your capture card’s settings are correctly configured to capture only game audio.

Q&A

Q: Can I record game audio only if I’m using a headset with a built-in microphone?

A: Yes, you can. Configure OBS to capture the game audio through the ‘Audio Output Capture’ source and ensure your headset’s microphone is muted or not included in the recording.

Q: My game audio isn’t being captured despite following the steps. What should I do?

A: Check that your game is running and outputting audio to the correct device. Try restarting OBS and your game. If the issue persists, consider using virtual audio cables or checking for compatibility issues.

Q: Is it possible to separate game chat audio from game audio in OBS?

A: Separating game chat audio from game audio can be tricky. It often requires the use of third-party tools or ensuring that your chat audio is routed through a separate audio device or application that can be captured independently in OBS.

Q: How do I reduce background noise while recording game audio?

A: Use noise suppression tools available in OBS or apply noise reduction filters in post-production software. Additionally, ensure your recording environment is as quiet as possible and consider using a noise-canceling microphone.

By following this comprehensive guide and considering the advanced tips and troubleshooting steps, you’ll be well-equipped to record game audio only using OBS, enhancing your streaming and recording experience.
