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. ## Key features - Audio-reactive video synthesis - Modular effects chain - Customizable masks (SVG, PNG, PDF) - Real-time feedback and distortion - Color manipulation and remap - CRT phosphor and DV tape emulation - Edge detection and raster effects ## Recent user reviews (3 of 3) All indexed reviews: https://appshunter.io/ios/app/aid/id6769789198/reviews.md ### 5/5 — This app is awesome! *2026-05-21* The amount of control over parameters is amazing. This app is so fun! ### 5/5 — I get it now *2026-05-20* Works so wild ### 5/5 — Inxane!!! *2026-05-18* 🤌🤌🤌 ## Frequently asked questions about A«iD ### What is A«iD? A«iD is an audio-reactive video synthesizer that generates and manipulates video in real time based on audio input. It is inspired by vintage electronic video synthesizers from the 1970s. ### Can I use my own images with A«iD? Yes, A«iD allows you to load your own SVG, PNG, or PDF files as custom masks. These can then be used to generate synthetic shapes and composite them over the video signal. ### How does the audio reactivity work in A«iD? A«iD listens to the live audio signal and extracts various parameters such as amplitude, bass, mid, and treble bands, beat phase, BPM, and onset triggers. These parameters can be wired to control virtually any knob in the app. ### What kind of visual effects are available in A«iD? A«iD offers a wide range of effects including feedback, keying, color matrix manipulation, hue oscillation, phosphor decay, DV tape emulation, halation, chroma smear, scan displacement, edge outline, colormaps, raster bending, mirroring, tiling, posterization, and channel mixing. ### Is A«iD available on Android devices? Currently, A«iD is supported on iPhone and iPad. Information regarding Android availability is not provided in the current data. ### How often is A«iD updated? The latest version of A«iD is 2.0, which was last updated on June 23, 2026. This suggests a recent update, but the frequency of future updates is not specified. ### What is the age rating for A«iD? A«iD has an age rating of 4+, making it suitable for a wide audience. This rating indicates it is generally appropriate for children. ### Does A«iD have ads? No, A«iD does not contain advertisements. The app is free to download and use without any ad interruptions. ## Version history (last 5 releases) ### 2.1 — 2026-07-09 2.1 Updates - last version for iOS 17+ Perform mode - Minimize the HUD for more viewing space on the canvas.
