Which look suits my genre?

Kick-driven music such as techno, drum and bass, dubstep or phonk suits Bass Tunnel, whose speed rides the bass; it is a Plus look, and free in Ambient Mode. Melodic, vocal or lo-fi music suits Neural Drift, the Julia set, whose shape follows the mids, and it is free.

How do I get clean audio in instead of room noise?

In Chrome or Edge on Windows, set Listening to Music / system and share the screen or tab your music plays in, with the audio box ticked. Otherwise, route your player or DJ software to a virtual cable, VB-Cable on Windows or BlackHole on a Mac, and choose it as the browser’s microphone, or pick your audio interface as the input.

Does it work with Spotify, YouTube Music or a DAW?

Yes, through system audio or a virtual cable, as above. It analyses the sound; it does not connect to any music service, so there is nothing to sign in to or authorise.

Is there a delay between the beat and the stream?

A small one. The dashboard analyses the sound in your browser and sends it to your OBS source about ten times a second, so the stream follows the music within a fraction of a second rather than on the exact frame; the dashboard preview itself is immediate. Browsers slow down background tabs, so the stream reacts most smoothly while the dashboard window stays visible.

Do I need an OBS plugin?

No. Vortexia uses the Browser Source that comes with OBS. If you would rather have a plugin, Waveform is a free, maintained one that draws a spectrum graph from an OBS audio source.

Yes. The free plan streams at 720p and 30fps with a small watermark, three engines and Twitch. Plus removes the watermark, renders at 1080p and 60fps, unlocks all eight engines and adds automatic YouTube and Kick events.

What is A Music Visualizer for OBS That Follows Your Mix?

Vortexia is a free music visualizer for OBS that needs no plugin: it runs in the Browser Source that comes with OBS, and the Vortexia dashboard, open in a browser tab, does the listening. For music the first question is where the sound comes from. A laptop microphone hears the room; Music / system, in Chrome or Edge on Windows, hears your player or DJ software directly, and elsewhere a virtual cable such as VB-Cable or BlackHole, or an audio interface, gives the same clean feed. The second is the look. The bass drives zoom, speed and glow, the mids reshape the pattern, and the treble makes the colour pop, so kick-heavy music suits Bass Tunnel, whose speed rides the low end, while melodic or vocal music suits Neural Drift, whose shape follows the mids. The dashboard detects each kick and sends it to OBS with the spectrum about ten times a second, so the stream punches on the beat within a fraction of a second. The free plan runs at 720p with a small watermark.
