If you play music on your stream or just want to add an audio visualizer to your stream for your microphone input, you have came to the right place. In this tutorial I am going to show you how to add an audio visualizer overlay to your stream in OBS Studio.

This means that your audience will get a visual representation of the audio coming through whatever source you choose. Let’s jump in and get started.

How To Add An Audio Visualizer To OBS Studio

To add an audio visualizer to OBS we need to use a third party plug in. The one we are going to use in todays tutorial is called Spectralizer. To install and use Spectralizer follow the steps below:

  1. Click here to get the download file for Spectralizer. The link will take you to a GitHub page where you can download Spectralizer for your operating system. We are going to be downloading the “spectralizerv1.3.4.installer.windows.exe file. Just click on the file name and it will start downloading.
  1. Once you have downloaded the file click on it to run the program (Make sure that OBS is closed while you are installing the plug in). This will install Spectralizer automatically into OBS. You will have to go through the setup wizard. Just follow the on Screen instructions and click next until you are finished.
  1. Now that Spectralizer is installed you can open OBS Studio. To add Spectralizer to your scene navigate to Sources –> “+” –> Spectralizer.
  1. Give your Spectralizer source a name and click OK. You will now see the panel where we can change our settings.

Here there are lots of options to customize your Audio Visualizer.


In mode there are three different modes to choose from Bars, Circular Bars or Wires. You can see what these look like below.

Circular Bars

Personally I like the standard Bars mode but you can choose the one which best fits your stream.

Audio Source

For your audio source you should pick the source that you want to control your bars. For example if you are playing music through your Desktop audio and want your bars to represent that, select Desktop Audio.

If you want the bars to represent your microphone input then select your microphone.


You can add a filter to your bars but I don’t recommend it. You can play around with them to see how they effect the visualizer.


You can adjust the color of your bars to match your streams branding.

Bar Width, Height & Spacing

You can adjust how your bars look by adjusting the size of your bars width, height and spacing.

Automatic Scaling

I would recommend leaving automatic scaling on to keep your bars scaled when you are adjusting the positioning and size in your scene.


By adjusting the gravity up or down you can control how the bars move. The higher the gravity the slower the bars will move.


If you want your bars to appear in stereo mode like below enable this feature.


Here you can decide how many bars you want to display at the same time. This will depend on how large you want your visualizer to be in your scene.

That is all the main features in Spectralizer. Once you have adjusted it to your liking you can click on OK and add it to your scene.

  1. Now the visualizer is in your scene you can adjust the sizing and position it where you like.

You now have an audio visualizer inside your OBS Studio scene using the Spectralizer plug in. It’s a nice little touch that can set apart your stream from others.

Can I Use An Audio Visualizer With My Microphone?

Yes, when you install a plugin such as Spectralizer you can select the input source. Select your microphone as your input device and the visualizer will move when you speak into the microphone.

Wrapping Up

Now your audience can sit and relax watching your visualizer bob up and down. There’s something so relaxing about watching the bars move. Let us know in the comments what your audience thinks of the visualizer.
