The ability to record or stream game audio consistently while switching between applications, or “alt-tabbing,” is essential for content creators. This functionality ensures that audio from the game being played is captured even when the focus shifts away from the game window, maintaining a seamless audio experience for viewers or listeners. This is achieved through specific configurations within Open Broadcaster Software (OBS).
Maintaining uninterrupted game audio during application switching enhances the viewing experience. It prevents audio dropouts that can be jarring and disrupt the flow of the content. Historically, achieving this required complex workarounds, but modern OBS features provide more streamlined solutions for consistent audio capture, improving the production value of gaming streams and recordings.
The subsequent sections will detail the methods and settings within OBS to enable persistent game audio capture, even when the game window is not actively in focus. These methods cover utilizing global audio devices, application audio capture, and other advanced configurations.
1. Audio Source Selection
Audio source selection within OBS is a foundational step in ensuring game audio capture persists even when the application loses focus. This initial configuration dictates how OBS identifies and captures the desired audio stream, directly influencing the success of continuous audio recording during application switching.
-
Desktop Audio Capture
This method captures all audio output from the system’s designated playback device. If the game audio is routed through the default output, selecting desktop audio will capture it. However, this also captures all other system sounds, potentially including notifications or other applications, which may be undesirable. Its simplicity makes it a common starting point, but its indiscriminate nature can create audio clarity issues, especially if multiple audio sources are active.
-
Specific Application Audio Capture
This allows OBS to target the audio stream from a specific application, such as the game executable. This approach isolates game audio, preventing other system sounds from interfering. This is often the preferred method for maintaining clean audio, as it directly addresses the target audio source. Implementation relies on the “Application Audio Capture (Beta)” source in OBS, which might have compatibility considerations with specific games or system configurations.
-
Audio Input Device Selection
While less common for game audio specifically, selecting an audio input device can be relevant if the game’s audio is routed through a virtual audio cable or other non-standard output. For instance, if voice communication software merges game audio into a single output, selecting that device as the audio input in OBS captures both. This configuration depends on the user’s audio routing setup and might require additional software like virtual audio cables.
-
Monitoring and Adjustment
Regardless of the chosen audio source, monitoring the audio levels within OBS is essential. Ensuring the game audio is being captured at an appropriate volume and free from distortion confirms the selected source is functioning as intended. Regular adjustments might be necessary based on the game’s audio levels and the user’s other audio sources, reinforcing the need for dynamic monitoring and source tweaking.
The choice of audio source in OBS dictates whether game audio capture remains consistent during application switching. While desktop audio capture offers broad coverage, specific application audio capture provides greater control and clarity. Proper selection, combined with diligent monitoring, ensures that audio transitions are seamless and uninterrupted.
2. Global Audio Devices
Global Audio Devices in OBS provide a means to define audio inputs and outputs that persist across all scenes within a project. This is directly relevant to consistent game audio capture during application switching because it ensures that the designated audio sources remain active regardless of scene transitions or changes in application focus. If game audio is configured to be captured via a global audio device, switching to another application via “alt-tabbing” will not interrupt the audio stream as OBS continues to monitor the defined device for audio input. For example, if “Desktop Audio” is configured as a global device and the game outputs sound to the default desktop audio device, the game audio will continue to be captured even when the game window is minimized or loses focus.
The alternative to using global audio devices is to configure audio sources within individual scenes. This approach can lead to audio disruptions when switching between scenes, and also when alt-tabbing, particularly if the audio sources are not configured identically across all scenes. Using global devices ensures that OBS has a consistent audio input to monitor, thus, preventing audio dropouts when focus shifts away from the game application. Furthermore, global audio devices are useful in maintaining a standardized audio setup across different streaming or recording sessions, streamlining the workflow.
The implementation of Global Audio Devices simplifies persistent game audio capture. The challenge lies in properly identifying the audio output device used by the game and configuring it as a global device within OBS. Regular checks of the audio levels are important to confirm the global devices are working as intended, especially after system updates or changes in the game’s audio settings. By understanding this functionality, content creators can minimize audio interruptions and ensure a professional viewing experience.
3. Application Audio Capture
Application Audio Capture in OBS directly addresses the challenge of maintaining consistent game audio recording when switching between applications. This feature allows OBS to specifically target and capture the audio output from a selected application, effectively isolating it from other system sounds. This isolation is paramount for maintaining a clean audio stream during gameplay, particularly when the user needs to interact with other programs, such as responding to messages or adjusting stream settings.
-
Targeted Audio Isolation
Application Audio Capture allows OBS to focus solely on the game’s audio, eliminating the need to capture the entire desktop audio stream. This minimizes the risk of inadvertently capturing unwanted sounds, such as system notifications, music playing in the background, or other application alerts. For example, during a live stream, a streamer can alt-tab to check chat without capturing the notification sounds that may distract the audience.
-
Persistent Audio During Focus Loss
When configured correctly, Application Audio Capture ensures that the game audio continues to be recorded or streamed even when the game window loses focus due to alt-tabbing. This is crucial for maintaining a seamless audio experience for viewers. Without this feature, alt-tabbing could cause the game audio to cut out momentarily, creating an unprofessional viewing experience. Games like strategy or simulation games that often require frequent alt-tabbing benefit significantly from this functionality.
-
Compatibility Considerations
While Application Audio Capture offers significant advantages, its compatibility can vary depending on the game and the operating system. Some games may not be properly detected by OBS, or the audio stream might not be accessible. In such cases, alternative methods like capturing the entire desktop audio may be necessary. Regularly testing the configuration with the intended game is essential to ensure compatibility and proper audio capture.
-
Resource Usage
Application Audio Capture may require slightly more system resources compared to capturing the entire desktop audio. This is because OBS has to actively monitor and isolate the audio stream from the specified application. On systems with limited resources, this could potentially impact performance. Monitoring CPU and memory usage during gameplay while using Application Audio Capture is advisable to identify any potential bottlenecks.
The selective capture of audio offered by Application Audio Capture provides a more refined approach to game audio management in OBS. Though considerations regarding compatibility and resource usage exist, the benefits of eliminating extraneous noise and maintaining continuous audio when alt-tabbing make it a valuable feature for content creators. The proper implementation of this feature contributes significantly to the quality and professionalism of the recorded or streamed content.
4. Audio Monitoring Settings
Audio monitoring settings within OBS play a vital role in confirming that game audio is being captured correctly, especially when alt-tabbing. Without proper monitoring, it becomes difficult to ascertain whether audio capture is consistent and free from errors during application switching. These settings provide a real-time feedback loop, allowing users to hear exactly what is being recorded or streamed, thereby enabling immediate identification and resolution of audio-related issues, such as muted audio or incorrect source selection after alt-tabbing.
The practical application of audio monitoring is evident in various scenarios. For instance, a streamer preparing for a live broadcast can use these settings to verify that the game audio is still present and at the appropriate levels after alt-tabbing to adjust stream settings. Similarly, a content creator recording gameplay footage can monitor the audio to ensure that no critical in-game sounds are missed during moments when focus is shifted away from the game. Different monitoring options, such as “Monitor Off,” “Monitor Only (Output),” and “Monitor and Output,” provide the flexibility to tailor the audio feedback according to individual preferences and recording or streaming setup. Selecting “Monitor and Output,” for example, allows the user to hear the audio while also broadcasting or recording it, enabling real-time adjustments to the audio mix.
In summary, audio monitoring settings provide a critical verification mechanism for game audio capture, ensuring a seamless and professional audio experience even when application focus is not constantly maintained on the game. Addressing challenges such as incorrect audio routing or muted audio requires the ability to listen to the captured audio, making monitoring settings indispensable for content creators relying on OBS for game recordings and streams. A thorough understanding and correct configuration of audio monitoring settings are essential for achieving reliable and consistent game audio capture during alt-tabbing scenarios.
5. “Use Device Timestamps”
The “Use Device Timestamps” setting within OBS has a direct impact on the consistency of audio and video synchronization, especially when the system’s workload fluctuates due to application switching, such as when alt-tabbing during game capture. This setting aims to mitigate potential audio drifting issues by relying on the timestamps provided by the audio device itself, rather than relying solely on OBS’s internal clock. This is especially important for audio that must sync precisely with gameplay footage.
-
Drift Correction
When “Use Device Timestamps” is enabled, OBS utilizes the audio device’s internal clock to maintain accurate synchronization between audio and video. This is crucial because system resource contention during alt-tabbing can lead to inconsistencies in OBS’s internal timing, causing audio drift. The device timestamps provide a more reliable reference point, minimizing the risk of audio gradually falling out of sync with the video. Games with critical audio cues, like rhythm games or competitive shooters, benefit significantly from this setting.
-
Reduced Latency
While primarily focused on synchronization, “Use Device Timestamps” can also contribute to reducing audio latency. By directly using the audio device’s timing information, OBS bypasses some of its internal buffering and processing delays. This reduction in latency is particularly noticeable in scenarios where real-time audio feedback is important, such as when a streamer is speaking over gameplay footage. The decreased delay between the streamer’s speech and its appearance in the stream enhances the viewing experience.
-
Hardware Dependency
The effectiveness of “Use Device Timestamps” depends on the quality and accuracy of the audio device’s internal clock. Some lower-end audio devices may have inaccurate or unstable clocks, which can negate the benefits of using this setting. In such cases, disabling “Use Device Timestamps” might actually improve synchronization. It is advisable to test with and without the setting enabled to determine the optimal configuration for a given hardware setup. High-quality audio interfaces generally provide more accurate timestamps.
-
Potential Conflicts
In certain scenarios, “Use Device Timestamps” can conflict with other audio processing tools or plugins. This can manifest as audio distortions, stuttering, or even complete audio dropouts. If such issues occur, disabling “Use Device Timestamps” may resolve the conflicts. Compatibility testing with different audio processing tools is essential to identify and mitigate potential issues. This setting should be evaluated in conjunction with other audio-related settings within OBS.

6. Background Audio Device
The “Background Audio Device” setting within OBS is not directly related to capturing game audio when the game window is out of focus (alt-tabbed). Typically, this setting refers to an audio input device that is consistently monitored by OBS, regardless of the active application. Its primary function is to capture ambient sounds or microphone input, ensuring that voice communication or environmental audio is always present in the recording or stream. As such, while potentially part of a broader audio setup, it does not inherently solve the challenge of maintaining uninterrupted game audio during application switching.
If the user’s intention is to capture microphone input while also ensuring game audio continues during alt-tabbing, then the Background Audio Device and game audio capture settings become interdependent. For example, a streamer might use the “Background Audio Device” to capture their microphone and then employ either desktop audio capture or application audio capture to ensure game audio is consistently recorded, even when they are not focused on the game window. The successful implementation of persistent game audio, in this case, necessitates independent and accurate configuration of both the dedicated game audio source and the background audio device.
In conclusion, the Background Audio Device setting in OBS serves a specific purpose distinct from directly addressing game audio continuity during alt-tabbing. However, in scenarios where both consistent voice communication and uninterrupted game audio are desired, the correct configuration of the Background Audio Device in conjunction with the appropriate game audio capture method is essential for a comprehensive and polished broadcast or recording. Failure to correctly configure either audio source results in an incomplete audio track, impacting the overall quality.
7. Audio Ducking Setup
Audio ducking is a signal processing technique that automatically reduces the volume of one audio source when another audio source is present. In the context of OBS and capturing game audio while alt-tabbing, audio ducking is primarily relevant when a user wants to ensure that voice communication, captured via a microphone, remains audible even when game audio is present. Although audio ducking does not directly impact the capture of game audio when the application loses focus, its correct setup is crucial for a polished end result, especially in live streaming or recorded commentary scenarios. Improperly configured audio ducking can result in either the game audio overpowering the microphone input, or the microphone consistently suppressing the game audio even when no speech is present, both of which detract from the viewing experience. For example, if a streamer alt-tabs to respond to chat while playing a game with a loud soundtrack, proper ducking would lower the game volume so the streamer’s voice is still easily understood.
Consider a scenario where a content creator uses OBS to record a gameplay walkthrough. The creator uses a microphone to provide commentary and wants the game audio to be audible but not to overpower their voice. If they were to alt-tab to view notes or guides, the game audio should ideally duck automatically when the commentator speaks, then return to normal levels when they are silent. This dynamic adjustment requires a well-configured audio ducking setup. The effectiveness of audio ducking is reliant on accurate threshold settings within OBS or external plugins. Threshold determines the audio level that triggers the ducking effect. Sensitivity controls how quickly and aggressively the ducking is applied, and release governs how quickly the ducking effect fades after the triggering audio source ceases. Inaccurate settings can lead to unnatural audio transitions.
In conclusion, while audio ducking does not inherently enable game audio capture during application switching, it is a vital post-capture processing step for creating professional audio. Understanding the parameters and proper configuration ensures that audio levels are balanced, creating a seamless and easy-to-understand audio experience for the audience. In combination with consistent game audio capture regardless of application focus, audio ducking contributes to the overall quality and accessibility of game-related content.

-
Audio Source Configuration Per Scene
Each scene can be configured to use different audio sources. For instance, one scene might use application audio capture to specifically record a game’s audio, while another scene relies on desktop audio. This flexibility is crucial when different scenes feature various audio requirements. In the context of maintaining continuous game audio while alt-tabbing, ensuring that the relevant scenes have the correct application audio capture source selected is vital. Failure to configure the source correctly in all relevant scenes can lead to audio dropouts when switching scenes, particularly when the game application loses focus.
-
Volume and Mixing Adjustments
Scene-specific volume and mixing adjustments allow for fine-tuning the audio levels for each scene. A scene showcasing a game with quiet audio may require a higher volume setting compared to a scene with louder commentary. These adjustments are necessary to ensure consistent audio levels across the entire stream or recording. When alt-tabbing from the game, a sudden volume spike or drop due to different scene settings would disrupt the listening experience. Therefore, each scene should be adjusted to maintain consistent volume levels regardless of the active application.
-
Filter Application
Different scenes might benefit from unique audio filters, such as noise suppression or equalization. One scene might need aggressive noise suppression to eliminate background noise from a microphone, while another requires subtle equalization to balance the audio. Applying these filters on a per-scene basis allows for tailored audio processing. If switching to a scene without the appropriate noise suppression, for example, could introduce distracting background noise even if the game audio is captured continuously during alt-tabbing. Careful configuration ensures audio quality remains consistent across all scene transitions.
