Resonance vs A«iD

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

A«iD is an audio-reactive video synthesizer inspired by Eric Siegel's legendary EVS Electronic Video Synthesizer from the 1970s. ——— THE CHAIN ——— Modules process the video signal in real time. Stack them in any order, tap to open controls, drag to reorder, long-press to bypass. GEOMETRY SOURCE — Generate a synthetic shape and composite it over the signal. Circle, diamond, bar, cross, ring, triangle, hexagon — or load your own SVG, PNG, or PDF as a custom mask. Position, size, hue, and edge softness are all independently audio-modulatable. FEEDBACK — Route the processed signal back into itself. Pinch and rotate on the canvas to control zoom and spin in real time. KEYER — Unified luma and chroma key in a single module. Cut foreground from background by luminance or isolate a color as a matte. Tap the eyedropper to sample any color directly from the screen. Pairs visually with COMPOSITE in the chain — the signal knows where it's going. COMPOSITE — Layer the processed chain behind a clean camera cut using luma and chroma mattes simultaneously. COLOR MATRIX — Rotate, invert, and cross-channel the RGB color space. Strange colors guaranteed. HUE LFO — Oscillate the hue channel at tempo-synced rates. Psychedelic pulsing locked to the beat. PHOSPHOR DECAY — Emulate CRT phosphor persistence. Past frames linger like burned afterimages. BURN ECHO — Additive frame echo that saturates toward white. Motion leaves a scorched trail. DV TAPE — Analog dropout and compression artifacts from the era of consumer DV camcorders. HALATION — Film halation glow on bright areas. Warm blooming on highlights. CHROMA SMEAR — Horizontal chroma bleed and compression fringing. SCAN DISPLACE — Rutt/Etra-inspired raster displacement. Each scanline shifts horizontally by audio frequency content mapped to vertical position — bass warps the bottom, treble the top. The entire frame becomes a spectrum warp field. EDGE OUTLINE — Sobel edge detection with colored glow, inspired by Stephen Beck's Direct Video Synthesizer. Flat areas go dark; edges light up in the chosen hue and bloom outward. COLORMAP — Remap luminance to color. Five palettes: Thermal (heat vision), Psychedelic (full hue rotation, classic Siegel PCS), Phosphor (P1 green CRT), Ice, and Neon. Every pixel's brightness becomes a new color. RASTER BEND — Distort the scan lines. Warp the geometry of the image itself. MIRROR — Fold, flip, and tile the frame into kaleidoscopic symmetry. TILE — Repeat, scale, and rearrange the frame in a grid. POSTERIZE — Reduce color depth. Hard edges, flat planes, screen-print aesthetics. TRANSFORM — Rotate, scale, and reposition with full affine control. CHANNEL MIX — Blend and cross-route RGB channels independently. ENCODER — NTSC-style composite encoding. Color bleeding and luminance separation. ——— AUDIO REACTOR ——— Every knob can be wired to the live audio signal. A»iD listens constantly and extracts amplitude, bass, mid and treble bands, beat phase, BPM, onset triggers, and spectral centroid. Seven LFOs run at BPM subdivisions. Open the Patch Bay to wire any source to any parameter in any module. Stack multiple sources on one knob. Set amount and polarity per patch. ——— RANDOMIZE ——— Shake the device (or hit the die) to randomize the whole chain. Palette Lock freezes hue and saturation through dice rolls. Sleeper Mode locks each module's bypass state — sleeping modules stay asleep, active modules stay awake. Everything re-rolls around your intention. ——— SYNC & CONTROL ——— ABLETON LINK — Lock BPM and beat phase with Ableton Live, AUM, Loopy, and any Link-compatible app on your network. MIDI — Auto-learns CC from any wired or Bluetooth MIDI controller. Long-press any knob to assign. OSC — Receive /aid/ messages from TouchOSC or Max/MSP over Wi-Fi.
