rusty_lights

Audio-reactive LED visualizer written in Rust. Captures audio via PipeWire, ALSA, or FIFO (MPD), runs it through a real-time DSP pipeline (FFT, Mel filterbank, beat detection), and drives LED strips over E1.31/sACN, DDP, or Art-Net. 7 built-in effects, multi-universe support, lock-free audio path. Targets Raspberry Pi with <5% CPU usage.
