Add a live, real-time audio visualizer to your Twitch stream — as an overlay, a BRB screen, or a full-panel background. Free, browser-based, no plugins.
Twitch is a visual medium, and the streams that stand out are the ones that feel produced and intentional — even when the content is casual. An audio visualizer overlay is one of the simplest ways to elevate the production quality of any stream. It gives viewers something to look at during music-heavy moments, makes your audio presence felt visually, and signals to new visitors that you take your stream seriously.
The WebGuysLLC Audio Visualizer is particularly well-suited to Twitch because it runs entirely in a browser — making it a perfect candidate for OBS's Browser Source feature or a Window Capture. All eight modes are available, and you can switch between them during your stream without going offline or interrupting anything.
The most popular Twitch use cases are: a corner overlay showing the Circular Wave reacting to your background music, a full-screen BRB or starting-soon screen with a slow, hypnotic visualization running, and a bottom-of-screen waveform strip using the Waveform mode as a subtle audio indicator during gameplay streams.
Follow these steps to add a live audio visualizer to your Twitch broadcast via OBS.
Navigate to webguysllc.com/visualizer/app in Google Chrome. Start the visualizer and confirm it's reacting to audio. For background music, use System Audio mode. For microphone input, select Microphone.
Choose your preferred visualization mode and color scheme. For Twitch, Circular Wave with Rainbow or Neon is the most viewer-pleasing. Adjust Sensitivity and Smoothing for your audio environment.
In OBS, open or create the scene where you want the visualizer to appear — your main stream scene, BRB scene, or starting-soon scene. Each scene can have its own visualizer configuration.
Click + in the Sources panel and select Window Capture. From the Window dropdown, select your Chrome browser window showing the visualizer. This captures the live, running visualizer including its audio reactivity.
Drag the Window Capture source to the desired position and size. For a corner overlay, resize it to roughly 400×400 pixels and position it in a corner. For a fullscreen BRB screen, stretch it to fill the entire canvas.
To show only the circular visualization without the control panel, right-click the source, select Filters, and add a Crop/Pad filter. Crop the right side to hide the control panel sidebar. For Circular Wave, additionally apply an Image Mask/Blend filter with a circular mask to isolate the bloom shape.
Start your Twitch stream from OBS as normal. The visualizer will be live in your stream, reacting to whatever audio is playing. Viewers in your chat will see it immediately.
Tell your chat what mode the visualizer is in and ask them to vote on which one they prefer. Switching modes live in response to chat requests is a great way to drive engagement — viewers love seeing the visual change in real time.
If you run a music stream with song requests, use the Circular Wave in fullscreen as your primary visual. The dramatic change in the visual when a new song starts naturally marks the transition for viewers.
Take a screenshot of the visualizer during a particularly dramatic moment and use it as your Twitch panel background, offline banner, or profile banner. The vibrant colors and dynamic shapes make for eye-catching channel art.
