About

DiscoBallLight

Features
Read full description

DiscoBallLight turns your iPhone or iPad into a light rig: the app listens to the music through the microphone and renders a light show in real time — bass, mids, highs and beats drive colors, motion and flashes. Point a projector at a disco ball, connect your device via HDMI or AirPlay and place the circle of light exactly on the ball: shape (round or square), size and position are fully adjustable while the rest of the screen stays black. An external display shows only the show — the controls stay on your device. No disco ball? Run the show fullscreen. • 13 light show styles with live preview, including Strobe, Duotone and Burst • Random white flashes in three strengths • Sensitivity slider with beat indicator and automatic volume balancing • Keystone correction and ellipse for projectors placed at an angle • Real-time microphone analysis, nothing is recorded or stored • No ads, no data collection Note: The show contains rapid light changes and strobe-like effects.
