Who this is for

Music streamers and producers
Just Chatting streams with background music
VTubers wanting a reactive backdrop

Overlay or backdrop

Run it as a full backdrop or a corner element. Pure Black background plus Screen blend in OBS makes the visual add light only.

React to voice too

Podcast mode tunes reactivity for speech, so a talking stream still gets gentle movement.

Keep it stable for hours

Auto performance holds frame rate; scene auto-cycle keeps it fresh; nothing expires or logs out.

How to do it

Open BLOOB with ?obs=1 in Chrome
Mic Input or a virtual cable
Window capture in OBS

Questions people ask about twitch music visualizer

Can viewers control it?

Not directly, but the phone remote lets a moderator drive scenes from anywhere on the same relay.

Does it work with Streamlabs?

Yes, the same window-capture approach works.

Will it show copyrighted music?

It only visualises; what you play on stream is your responsibility.

Any cost?

None. Support is optional.

Free forever — help keep it that way. There is no paywall, no watermark and no ad. Support pays the hosting and the phone-remote relay servers and funds new scenes. ♥ Support BLOOB & Galaxy What it funds
