Live
Turn every phone in the audience into part of the set.
Audience members scan a QR and the deck pushes content to their screens (and flashlights, on capable devices) in time with the music. Two channels — a lightweight state channel for colors / strobes, and an optional video channel that fans out the engine canvas via the SFU.
Color + strobe: solid colors on a synced strobe pattern, drive everyone's screen the same color on the kick. Flashlight pulse: pulses the phone's rear LED on detected beats (Chrome Android, iOS 17.4+). Video chunks: the actual engine canvas streamed to each phone for fully synchronized visuals. Hybrid: state + video at the same time.
A QR overlay appears on the source preview by default — position + scale tunable from the inspector. Audience scans, lands on /crowdstream/<code>, taps "Tap to start", and they're in.
State channel: under 250 ms on a stable network. Video channel: 400–800 ms typical depending on uplink and the SFU's nearest region.
