Audio-reactive kaleidoscope visualizer with MIDI input and video export
Abstrakt Deck turns live audio into generative visuals in real time. Feed it
microphone, system audio, or MIDI and it renders reactive kaleidoscopes,
particle fields, and video-feedback effects on the GPU at full frame rate.
Built in Rust on wgpu — runs on Vulkan and stays fast on integrated graphics.
- Per-band audio detection with ADSR envelopes and tempo tracking
