Liquid Neon: Flow With The Music — Organic fluid motion with chromatic RGB splits. Liquid Neon is one of Vortexia's flagship visual engines, rendering fluid, neural-drift patterns that morph with the full frequency spectrum. The whole engine runs in WebGL inside a regular browser tab — there is no plugin, no install and no DAW integration required. It listens to the audio your machine is already playing, runs a real-time FFT, and drives motion separately on bass, mid and treble bands so each layer of the mix gets its own visual response. You drop it into OBS, Streamlabs and any other broadcasting software as a Browser Source by pasting one viewer URL. Free tier covers 720p watermarked; Plus is $4.99/month for 1080p/60; Pro is $14.99/month for 4K/60 with a brand-kit logo overlay. Tweak colour shift, zoom and iteration depth from the dashboard, save the result as a preset, and the same URL keeps the visual identical across every show.
How to use Liquid Neon: Flow With The Music
Customize the visual. Open the Vortexia dashboard, choose the Liquid Neon: Flow With The Music 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, Streamlabs and any other broadcasting software. In OBS, Streamlabs and any other broadcasting software, 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
What does the Liquid Neon engine actually do differently?
It renders fluid, neural-drift patterns that morph with the full frequency spectrum. Sound is read as a 128-bin spectrum every frame rather than as one loudness figure, and for this engine the mids walk the Julia constant, so melody morphs the shape rather than just brightening it. It costs about 1ms per frame at 1080p.
What does the free tier actually include?
Three of the eight engines at 720p and 30fps with a small watermark, Twitch integration, and no time limit or card — a tier rather than a trial. Plus is $4.99 a month (or $49.99 a year) and removes the watermark, unlocks 1080p at 60fps, all eight engines including the two 3D ones, and YouTube, Kick and TikTok. Pro at $14.99 a month adds 4K and a logo overlay, and there is a $149 one-time lifetime licence.
Does it really react to the music, or is it a loop?
It is generated live on your GPU. A 128-bin FFT runs every frame and the three bands drive different things, so a kick and a cymbal at the same volume produce different motion. On this page's Liquid Neon engine specifically, the mids walk the Julia constant, so melody morphs the shape rather than just brightening it. Nothing repeats, and you can zoom to 100,000x magnification while it is running — neither is possible with a pre-rendered clip.
Can I keep this exact look?
Yes. Adjust colour shift, zoom, iteration depth, kaleidoscope and aberration in the dashboard and save it. Your viewer URL reproduces the look identically every time, and changes you make while live reach the Browser Source within about a second over server-sent events, so you can adjust mid-stream without touching OBS.
Does it react to my Twitch subs and raids, or only to audio?
Both, and the event side is the part audio visualizers cannot do. Connect Twitch, YouTube or Streamlabs and subscriptions, gift subs, bits, follows, raids and hype trains each trigger their own treatment — a raid pulls the camera back and sends a band outward, a hype train holds a sustained swirl for as long as the train runs. Reacting to a raid needs an authenticated connection to the platform and a webhook, which is why a tool that only analyses a waveform has no way of knowing one happened.
Which browsers and operating systems work?
Anything with WebGL2: current Chrome, Edge, Firefox and Safari on Windows, macOS, Linux and ChromeOS, including the embedded Chromium inside an OBS Browser Source. If WebGL2 is unavailable the page says so rather than showing a blank screen.
