Audio-reactive 3D geometry
Cylinder and sphere rotate in real time, each tuned to fill the frame. Beat-driven shake on X/Y, with four ribbons that collapse to bass, mid, treble and overall level.
Native Android · up to 120 Hz · OpenGL ES 3.0
Turn any song into a living mandala —
and export it as video.
Real-time audio visualizer · kaleidoscope mandalas · hardware MP4 up to 4K.
abstrakt engine wraps 3D geometry in audio-reactive textures, folds them into kaleidoscope mandalas, and captures the result as an H.264 MP4 with your audio already muxed in — entirely on your device.
Built to react to sound
Pick an audio file or tap the mic, choose a skin, and watch a rotating 3D shape painted with shader color or your own photo — folded into a radially symmetric mandala that pulses on every beat.
▦
Painter textures
A 4096×256 texture painted stripe-by-stripe every revolution — hue stripe, audio paint, print head, or a photo you supply.
✦
Kaleido instrument
Fold 2–24 ways (Mirror, Hex, Star…), lock 4-fold Diamond/Square symmetry, choose from eight SDF frame shapes, and tune beat sensitivity live.
🎙
Live mic input
Tap the mic to drive the visuals from the room around you instead of a file — playback pauses and resumes automatically.
⬛
Make your own skins
Capture a mosaic from any moment, preview the 8×8 grid, keep it — now it's a reusable audio-reactive skin. 5 built-in plus up to 10 of your own.
🔒
Private by design
Runs entirely on-device. No accounts, no sign-in — your audio, photos, skins and exports never leave your phone.
Export a real MP4. Up to 4K. Hardware-fast.
Tap ↓ → Export Wizard. abstrakt engine renders offline at the live framerate, then muxes your audio track. On a Galaxy S25, 4K runs at 4–5× real-time.
