Resonance: Visual Instrument

Turn sound into a living visual instrument. Create stunning real-time visuals with hand tracking, cinematic skins, and GPU-powered effects.

Resonance turns sound into a living visual instrument — transforming audio into mesmerizing, real-time visuals powered by GPU acceleration, right on your iPhone.

Whether you're a musician, content creator, DJ, or just love visual effects, Resonance lets you see your music come alive through four hand-crafted visual skins, each powered by custom Metal shaders.

FOUR CINEMATIC VISUAL SKINS

◆ Field — Organic, flowing wave patterns that ripple and pulse with your audio. Smooth and hypnotic.

◆ Signal — A digital glitch aesthetic with corruption effects that sync to every beat. Tap the screen to trigger glitch bursts.

◆ Matrix — Cinematic falling glyphs with layered depth and real-time motion. Streams emanate from your hands and face, creating a fully immersive effect.

◆ Aura — Luminous energy effects that follow tracked objects, creating multi-point auras that breathe with the music.

REAL-TIME HAND & FACE TRACKING

Point your camera at yourself or others — Resonance detects hands, faces, and body silhouettes using Apple's Vision framework. Visual effects react to your position, creating an interactive experience that goes beyond passive visualization.

◆ Hand pose detection with fingertip tracking ◆ Face detection and position tracking
◆ Person segmentation for background separation ◆ Tap-to-track any object on screen

MULTIPLE INPUT MODES

◆ Live Microphone — Visualize any sound around you in real time ◆ Live Camera — Combine audio-reactive visuals with your camera feed ◆ Video Import — Apply skins and tracking to any video from your library ◆ Image Import — Use a photo as your canvas with crop tools

RECORD & SHARE

Capture your creations as video. Resonance records rendered frames directly to disk at 30 FPS, syncs audio perfectly, and exports polished MP4 files ready for social media, music videos, or live performance content.

BUILT FOR PERFORMANCE

Every visual is rendered on the GPU using Apple's Metal framework with custom shaders. FFT audio analysis runs through the Accelerate framework, delivering responsive, low-latency visuals that react to bass, mids, and highs independently.

Perfect for: • Music videos & visualizers • Live performance visuals • Social content creation • Creative experimentation • VJing & live events
