Ritmolux ~ Real-time Music Visualizer
A lightweight, real-time music visualizer built around one shared Rust core that turns a stream of PCM audio samples into GPU-rendered visuals. Two frontends consume that core:
- Standalone app (Windows, macOS and Linux) — pure Rust (
winit+wgpu), fed by the OS’s system-audio capture.- foobar2000 plugin (Windows-first) — a thin C++ shim over the core’s C ABI, fed by foobar’s own
visualisation_stream(no loopback needed on that path).The core is source-agnostic: it takes interleaved/mono PCM frames and does not care whether they came from loopback capture or foobar. That single abstraction is what lets one visual codebase serve both frontends.

thinksynth ~ Modular Synth & Algorthmic Composition
thinksynth builds sounds out of a graph of DSP nodes — oscillators, filters, envelopes, delays and arithmetic — described in a small language and rendered in real time. Patches assign those graphs to MIDI channels, so one instrument can layer several voices.
Every node is a plugin, and the set that ships covers subtractive and FM synthesis, resonators, waveshaping and a range of filters. New ones are ordinary shared libraries dropped into the plugin directory.

Spatial-Linux ~ Boom 3D FOSS Alternative
3D sound for every app on your Linux desktop. Looking for Boom 3D on Linux? Spatial Linux is a free, open-source alternative. It adds a virtual output device to PipeWire and processes everything you play through it: 3D surround for headphones, a room around the music, clarity, bass and a night mode, plus a 10-band equaliser. You can also set each app’s volume separately — game chat quiet, music loud — right from the app. It runs entirely on PipeWire’s built-in filters, so no extra audio plugins are needed.
