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.

ShinRonin ~ Modular Filter & Delay


ShinRonin is a ground-up rebuild of Ronin, one of the earliest plugins we ever shipped, first released in 2003. The original paired two delay lines with a set of morphing filters and two fully patchable routing matrices, and it earned a cult following for the strange feedback networks and self-oscillating textures you could build inside it. Twenty years on, we have rebuilt it for modern systems, kept the architecture that made it worth remembering, and released it for free.

Two independent delay lines, each with tempo sync, reverse, looping, and feedback, feed a pair of morphing multimode filters that sweep continuously from notch through lowpass, bandpass, and highpass. There is saturation, two LFOs, and an envelope follower. Everything connects through two on-board matrices: a signal matrix that routes any audio source to any destination, and a modulation matrix that wires the LFOs, envelope, and incoming MIDI to nearly any parameter. It is happy doing clean stereo delays and gentle filtering, but the real fun starts when you patch a feedback loop and let it misbehave.

SC55-CLAP ~ Nuked SC-55 CLAP Plugin


Nuked SC-55 CLAP is a CLAP audio plug-in built upon J.C. Moyer’s fork of nukeykt’s Nuked-SC55, an emulation of the Roland SC-55 Sound Canvas MIDI module.

Unlike the original Nuked-SC55, this version has no graphical user interface. It reacts to MIDI messages like an external MIDI module and is intended for retro gaming, hobby music, and research.

The plug-in supports ROM versions from several original SC-55 models, including the SC-55 v1.00 through v2.00 and SC-55mk2 v1.01. It runs on Windows, macOS and Linux. The project is based on the original MAME license, which includes restrictions on commercial use, including commercial music production and inclusion in commercial software packages.

The project describes its purpose as helping preserve DOS gaming history while providing historically accurate SC-55 sound through a modern CLAP plug-in.

Note: The plug-in requires ROM dumps from the original hardware; the ROMs are not included with the project.
