SyncFlash – Real-Time Audio Reactive Strobe Light

SyncFlash transforms your phone into a real-time audio-reactive strobe light that syncs your camera flash (and optional vibration) to music beats around you.

Whether you're at a house party, small studio session, dorm gathering, or just vibing in your room, SyncFlash listens to ambient sound and converts intensity peaks into synchronized light pulses for an immersive, concert-like atmosphere.

🎵 How It Works

SyncFlash uses your microphone to:
Acoustic Signal → Digital Audio Stream → Peak Detection → Flash + Vibration Sync
The result? Perceptual beat-matched flashlight pulses that react instantly to music energy, bass hits, and rhythm spikes.
This isn’t a simple blinking flashlight — it’s a dynamic, audio-driven strobe engine tuned for party energy.
