How to Record Game Audio Only in OBS Studio (Step by Step Guide)

In this video, I will show you how to record game audio only in OBS studio using Diablo 2 Resurrected as an example.

Open the game first and minimize it. Then, go to OBS studio and click on the “plus” sign” in the source tab. Select the “Application Audio Capture Beta” option. I will rename this to “Diablo 2 Audio”. Click on okay.

Then, select “Diablo 2 Resurrected” as the window to capture. Click okay. You need to do this for any new game you want to record audio on.

Now, you will want to mute the Desktop and Mic audio by clicking on the sound icon under the Audio Mixer tab to avoid recording unnecessary background sounds.

Click the 3 dot icon on the “Diablo 2 Audio” section. Select “Advanced Audio Properties. Make sure track number 1 of “Diablo 2 Audio” is checked. This is where the game audio is recorded. Close it and go to the settings option.

Go to the output tab and select “advanced” under output mode. Then, select the “recording tab” and make sure the “audio track 1” is checked. Click on apply and okay to exit settings.

You can start recording game audio now by playing the game. However, to record game footage alongside the audio, you need to setup gameplay recording.

Click on the “plus” icon under audio tab. Then select “game capture”. I will rename this “Diablo 2 Recording” and click okay.

Next, select “Capture Selected Window” as the option for “mode”. Then, under “window”, select “Diablo 2 Resurrected”. Click okay.

Now you are ready to record. Start recording by clicking here. Here is an example of the audio alongside the gameplay footage.

You can stop recording after minimizing the game and press “stop recording”. Thanks for watching!
