How to Split Audio in OBS: A Comprehensive Guide to Mastering Your Sound

Splitting audio in OBS (Open Broadcaster Software) is a crucial skill for content creators, streamers, and podcasters who want to have full control over their audio sources. Whether you’re looking to separate game audio from your microphone, or you want to isolate specific sounds for post-production, OBS offers a variety of tools to help you achieve this. In this article, we’ll explore multiple methods to split audio in OBS, discuss the benefits of each approach, and provide tips to optimize your audio setup.

Why Splitting Audio in OBS is Important

Before diving into the technical aspects, it’s essential to understand why splitting audio is so important. When you’re streaming or recording, you often have multiple audio sources, such as your microphone, game audio, music, and even sound effects. If all these sources are mixed into a single audio track, it becomes challenging to adjust individual volumes, remove unwanted noise, or apply effects in post-production. By splitting your audio, you gain the flexibility to fine-tune each source independently, resulting in a more professional and polished final product.

Method 1: Using Multiple Audio Tracks in OBS

One of the most straightforward ways to split audio in OBS is by using multiple audio tracks. OBS allows you to assign different audio sources to separate tracks, which can then be exported individually during recording or streaming. Here’s how you can set this up:

  1. Open OBS and go to Settings: Navigate to the “Output” tab and select the “Recording” section.
  2. Enable Multiple Audio Tracks: Under the “Audio Track” settings, check the boxes for the tracks you want to use. OBS supports up to six audio tracks.
  3. Assign Audio Sources to Tracks: Go to the “Audio Mixer” panel, click the gear icon next to each audio source, and assign it to the desired track.
  4. Record or Stream: When you start recording or streaming, OBS will save each audio source to its respective track.

This method is particularly useful if you plan to edit your audio in post-production, as it allows you to isolate and manipulate each source independently.

Method 2: Using Virtual Audio Cables

Virtual Audio Cables (VACs) are software tools that create virtual audio devices on your computer, allowing you to route audio between applications. By using a VAC, you can split your audio sources before they even reach OBS, giving you even more control over your audio setup.

  1. Install a Virtual Audio Cable: There are several VAC options available, such as VB-Cable or Voicemeeter. Download and install the one that best suits your needs.
  2. Configure Your Audio Sources: Set your microphone, game audio, and other sources to output through the virtual cable.
  3. Set Up OBS: In OBS, add the virtual audio cables as separate audio sources. This way, each source will be treated as an independent input, allowing you to split and adjust them individually.

Using a VAC can be a bit more complex than the multiple tracks method, but it offers greater flexibility, especially if you’re working with multiple applications or need to route audio in specific ways.

Method 3: Using Audio Filters in OBS

OBS also provides built-in audio filters that can help you split and manipulate your audio in real-time. While this method doesn’t create separate tracks, it allows you to apply effects, adjust volumes, and control audio levels on the fly.

  1. Add an Audio Source: In OBS, add your audio source (e.g., microphone, game audio) to the scene.
  2. Apply Filters: Right-click on the audio source in the “Audio Mixer” panel and select “Filters.” Here, you can add various filters such as noise suppression, gain, and compression.
  3. Adjust Settings: Use the filters to isolate specific frequencies, reduce background noise, or enhance certain aspects of your audio.

This method is ideal for streamers who want to make real-time adjustments to their audio without the need for post-production.

Method 4: Using External Audio Mixers

For those who want the ultimate control over their audio, an external audio mixer can be a game-changer. An audio mixer allows you to physically split and adjust your audio sources before they even reach your computer.

  1. Connect Your Audio Sources: Plug your microphone, game console, and other audio sources into the mixer.
  2. Adjust Levels: Use the mixer’s knobs and sliders to adjust the volume, EQ, and other settings for each source.
  3. Connect to OBS: Output the mixed audio to your computer and add it as an audio source in OBS.

While this method requires additional hardware, it provides unparalleled control over your audio and is often used by professional streamers and podcasters.

Tips for Optimizing Your Audio Setup

  • Test Your Levels: Before going live or recording, make sure to test your audio levels to ensure everything sounds balanced.
  • Use Headphones: Wearing headphones can help you monitor your audio in real-time and catch any issues before they become a problem.
  • Keep Your Software Updated: OBS and virtual audio cables are regularly updated with new features and bug fixes. Make sure you’re using the latest versions to take advantage of these improvements.
  • Experiment with Filters: Don’t be afraid to experiment with different audio filters to find the perfect sound for your content.

Q: Can I split audio in OBS without using multiple tracks? A: Yes, you can use audio filters or virtual audio cables to split and manipulate your audio without creating separate tracks.

Q: How many audio tracks can OBS support? A: OBS supports up to six audio tracks, allowing you to split and manage multiple audio sources independently.

Q: Do I need an external audio mixer to split audio in OBS? A: No, an external mixer is not necessary, but it can provide additional control and flexibility for advanced users.

Q: Can I split audio in OBS for live streaming? A: Yes, you can split audio in OBS for both live streaming and recording, giving you the flexibility to adjust your audio in real-time or during post-production.

By mastering these methods, you’ll be well-equipped to split and manage your audio in OBS, ensuring that your streams and recordings sound professional and polished. Whether you’re a beginner or an experienced content creator, these techniques will help you take your audio to the next level.
