A Comprehensive Guide to Using the Audio Mixer in OBS Studio

Introduction

Welcome to OBS 3D tutorials! In this article, we will provide a comprehensive guide to using the audio mixer in OBS Studio. The audio mixer is a powerful tool that allows you to control and adjust different audio options within OBS Studio. By the end of this guide, you will have a thorough understanding of the features, tips, and tricks of the audio mixer, allowing you to make the most of your audio setup in OBS Studio.

Set up a voice mixer

To start using the audio mixer in OBS Studio, follow these steps:

1. Open OBS Studio and make sure a new profile and scene group have been created.
2. Select the desired scene and click on the plus icon under \"Sources.
3. Choose "Audio Input Capture" from the options.
4. Select the microphone you want to use and click OK to set it up.

Once you've added an audio device to the audio mixer, you'll see a sound level meter displaying three levels: green, yellow, and red. This meter represents the volume of audio input, and turns while speaking. You can use the volume slider to adjust your voice or mute the audio capture altogether.

Add multiple audio sources

If you need to add multiple audio sources, follow these steps:

1. Click the plus icon on the audio mixer.
2. Select \"Capture Audio Input\" again.
3. Give a name to pick up the new sound (for example, Microphone 2) and click OK.
4. Choose the desired microphone to pick up the new sound and click OK.

You will now see outputs for both audio sources in the audio mixer. If the volume is too high for one of the sources, you can adjust it by lowering the volume slider to prevent it from reaching the red zone. This way, you can ensure a balanced volume for all sources.

Manage audio levels with video capture devices

In the case of a video capture device with an audio component, you can independently control the audio. Here's how:

1. Add the video capture device as the source in OBS Studio.
2. To discard audio from the video capture device, tap the mute icon on the audio mixer. This action will mute only the audio from the video capture device, while other audio sources remain active.

Customize the sound mixer layout

To optimize your workspace in OBS Studio, you can customize the layout of the audio mixer. Here's how:

1. Right-click anywhere in the audio mixer or click on the three dots.
2. Choose the option \"Vertical Layout\" to arrange the devices vertically for clearer output.
3. You can add multiple devices and adjust their size or mute/unmute them as needed.
4. If you prefer horizontal layout, right-click again and uncheck the option \"Vertical Layout\".

Moreover, you can hide certain devices to disassemble the audio mixer:

1. Right-click on the device icons.
2. Select \"Hide\" to hide a specific device from the audio mixer.
3. To show all hidden devices, right-click and choose "Show All".

In addition, you can rename the devices to offer more meaningful labels:

1. Right-click the device icon.
2. Select \"Rename\" and enter the desired name of the device.
3. Click OK to save the new name.

Apply filters to audio sources

The audio mixer in OBS Studio allows you to apply filters to improve the sound quality. Here's how to apply filters:

1. Select the audio source you want to apply the filter to.
2. Click on the filters icon (represented by the plus icon of the plus sign).
3. Choose the desired filter, such as a compressor, to improve the sound quality.
4. Adjust the filter settings as needed.
5. To apply the same filter to another audio source, right click on the original source, go to "Copy Filters", then right click on the target source, and choose "Paste Filters".

Modify audio source properties

If you need to change the properties of the audio source, such as the device used, follow these steps:
