DJ visualizer: beat-synced visuals for live sets

Visuals as a layer, not a crutch

A DJ visualizer should reinforce groove, not distract from mixing. Beat Visualizer is built for second-screen or projector use: fullscreen, dark chrome by default, and overlay controls that dim when the crowd should focus on the room.

Beat sync modes

Use 8 / 16 / 32 beat intervals when you want predictable structure during a planned set. On drop is more dramatic but can feel busy in intimate rooms. Smart sync tries to phrase with estimated BPM — great for open-format nights when BPM swings.

Audio routing realities

Browsers expose microphone input reliably; system / mixer loopback depends on the OS. Many DJs route booth or master into an interface channel that the browser sees as a mic, or use OBS audio monitoring into a virtual device.

Safety

Strobe-like modes can trigger photosensitive viewers — announce or avoid aggressive strobes in public gigs.
