Ritmolux ~ Real-time Music Visualizer

Posted by tom2tec on

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

Posted by tom2tec on

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.

foo_dsp_speaker_range ~ Speaker Range Cropping

Posted by tom2tec on

foo_dsp_speaker_range is a foobar2000 DSP component for Windows x64. It adds Speaker Range Crop, a configurable Linkwitz-Riley 4th-order high-pass/low-pass filter intended to limit playback to a loudspeaker’s reproducible range.

The filter sections use Vicanek matched (decramped) coefficients instead of bilinear-transform designs, so the magnitude response stays close to the analog Linkwitz-Riley prototype near Nyquist. In practice this means a 20 kHz low-pass stays active and tracks the intended response at 44.1 kHz, where bilinear/RBJ-style low-pass biquads cramp toward their forced null at Nyquist. The DSP uses causal IIR filters with no lookahead and reports zero processing latency to foobar2000. Reference: M. Vicanek, “Matched Second Order Digital Filters” (2016), vicanek.de/articles/BiquadFits.pdf.

Spatial-Linux ~ Boom 3D FOSS Alternative

Posted by tom2tec on

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.
