How to Make OBS Only Record Game Audio | Ultimate Guide

OBS (Open Broadcaster Software) is open-source software for video recording and live streaming. It can work with multiple systems, including Windows, Mac, and Linux. It’s able to seamlessly record computer screens and pick up audio. Many users utilize this software to record gameplay, TV shows, and other videos with sound. Can OBS only capture audio not others? The answer is negative. OBS doesn’t support audio-only recording, but you can record audio from the game and the microphone (in video format).

Now, follow the specific instructions below to learn how to make OBS record only game audio on Windows and Mac.

Recording external sound through the microphone is simple. Windows has a pre-introduced sound recorder, so you don’t need to compose one yourself. To record audio that is coming from the device itself, such as gaming sound and internet music, we will record only audio from the computer’s internal speakers by doing the following:

Step 1. Launch OBS. Go to Controls and click Settings.

Step 2. Choose Audio in the left panel. In the Global Audio Devices tab, set Desktop Audio as default and keep other audio sources disabled. Click Apply/OK to save the change.

Step 3. You can select a video resolution and configure output settings based on your preference.

Step 4. Once the audio bitrate is configured as shown below, you’re finished. Then you can record the internal audio from games, browsers, and other applications without adding a video source.

Apple has disabled the sound recording from the Mac framework. To begin OBS record only game audio, you need to acquire the necessary equipment, a recording program, and an editing application if you recorded the sound and game audio separately. Here is how to make OBS only record game audio on Mac:

Step 1. Launch and Create New Audio Recorder Setup: add the + symbol and create the project. Right-click in the Mixer area and open the Advanced Audio Properties.

Step 2. Use the Customize Record Only Feature to hear the sound of the source directly from your desktop. Once you have enabled this feature, head toward the recording interface.

Step 3. Set the Screen and Output Mode, which will hear the sound from the source stream and desktop at the same time. After that, click the Record button to start recording your game audio simultaneously.

Step 4. OBS Studio for Mac will export the monitor audio to the default playback device. You can also open the OBS settings and click on the Audio tab to change the monitoring output device.
