Visualize Audio in Your OBS Dock — Real-time fractal feedback for audio monitoring. Vortexia is a browser-based audio-reactive visualizer that plugs straight into OBS Studio. The Chaos Prime engine renders organic, slowly-evolving fractal structures that breathe with mid-range audio on your GPU, streams as a Browser Source, and reacts to whatever audio your output is already mixing. Free tier runs at 720p with a watermark; Plus removes the watermark at 1080p/60; Pro ships 4K/60 with custom shaders. You don't install anything: paste the viewer URL into OBS Studio, set the canvas size, and the visuals are live. Because the engine is generative, no two seconds look identical — important for avoiding the static-loop look that hurts retention. Customize colour, intensity and reactivity from the dashboard, save it as a preset, and reuse the same URL on every show.
How to use Visualize Audio in Your OBS Dock
Customize the visual. Open the Vortexia dashboard, choose the Visualize Audio in Your OBS Dock preset, and adjust colour shift, zoom and iteration depth until it matches your show.
Copy the viewer URL. Click "Get Browser Source URL" — Vortexia will give you a permanent URL that loads this exact configuration anywhere.
Add it to OBS Studio. In OBS Studio, add a new Browser Source, paste the viewer URL, and set the canvas to 1920×1080 (or 1080×1920 for vertical). The visual is live as soon as the source loads.
Route your audio. Make sure the browser tab can hear the audio you want it to react to — most streamers route their stream output through a virtual audio cable so Vortexia and OBS hear the same mix.

Frequently asked questions
Is Visualize Audio in Your OBS Dock really free?
Yes. The free tier of Vortexia runs at 720p with a small corner watermark, on a single platform. Plus ($49.99/year) removes the watermark at 1080p/60 across multiple platforms, and Pro ($119.99/year) ships 4K/60 with custom shader uploads. There is also a $149 one-time lifetime licence.
How do I add Vortexia to OBS Studio?
Open the Vortexia dashboard, customize the visual, click "Get Browser Source URL" and copy it. In OBS Studio, add a Browser Source, paste the URL, set the canvas to 1920×1080 (or 1080×1920 for vertical), and the visual is live. Audio reactivity uses the audio Vortexia hears — most streamers route their existing stream output to the browser tab.
Does it actually react to the music or is it pre-rendered?
It's fully generative and runs in real time on your GPU. The Chaos Prime engine performs a live FFT on the audio and drives bass, mid and treble bands separately — kick drums, leads and pads each pull their own motion. No two seconds of output look the same, which is why it doesn't end up looking like a 30-second .webm loop on repeat.
Will it slow down my stream?
Vortexia runs on your GPU, not your CPU, so it doesn't fight OBS's encoder for the same resources. On a modern laptop GPU the engine renders comfortably at 1080p/60. If you're on integrated graphics, drop the canvas to 1280×720 in the Browser Source settings — the visual still looks clean because the fractal motion isn't resolution-dependent.
Does it work on Mac, Windows and Linux?
Yes. Because Vortexia is a browser-based WebGL engine, it runs anywhere a recent Chrome, Edge or Firefox does — including Mac, Windows, Linux, ChromeOS, and the embedded Chromium that ships with OBS Browser Source.
