Inspired by the legendary work at [oscilloscopemusic.com](https://oscilloscopemusic.com).\n\n## Demo Video\n(click to watch on YouTube)\n[![Watch the demo](https://img.youtube.com/vi/yX30gl02Jhc/0.jpg)](https://www.youtube.com/watch?v=yX30gl02Jhc)\n\n## Installation\n\nYou can download the latest builds for macOS, Windows, and Linux from the [Releases page](https://github.com/dfl/faveworm/releases).\n\nMacOS users: right-click and select \"Open\" to run the app the first time, in order to bypass \"unidentified developer\" warnings.\n\n---\n\nBuilt on the shoulders of giants with [Visage](https://github.com/VitalAudio/visage), Faveworm features a custom physics-based beam renderer raided from [Laurent de Soras' faveworm rendering plugin for Vapoursynth](https://ldesoras.fr/prod.html#src_vs).\n\n\u003c!-- ![XY Mode Visualization](images/screenshot.png)\n\n## Display Modes\n\n| Mode | Description |\n|------|-------------|\n| **TimeFree** | Classic horizontal sweep, free running. Good for checking levels. |\n| **TimeTrigger** | Locked horizontal sweep. Stays steady on periodic signals. |\n| **XY** | The main event. Left channel = X, Right channel = Y. Pure math aesthetics. |\n\n## Controls\n\n### General\n| Key | Action | Note |\n|-----|--------|------|\n| `M` | Cycle Mode | Switch between the 3 modes above |\n| `Space` | Play/Pause | Stop time (or just the audio) |\n| `B` | Bloom | Toggle that sweet, hazy glow |\n| `P` | Persistence | Toggle phosphor trail memory |\n| `Up/Down` | Intensity | Crank the beam brightness |\n\n### Trigger Mode\n| Key | Action |\n|-----|--------|\n| `L` | Lock | Toggle autocorrelation locking (steady!) |\n| `E` | Edge | Rising vs. Falling edge trigger |\n| `Shift+Up/Down` | Threshold | Set the trigger point |\n\n### Filter (XY Mode)\nThis is where the magic happens. We use a State Variable Filter to phase-shift the stereo signal, turning mono sources into rotating 3D-like structures.\n\n| Key | Action |\n|-----|--------|\n| `F` | Filter Impulse | Toggle the SVF on/off |\n| `S` | Split Mode | **Stereo Split**: Sends different filter responses (LP, HP, BP, etc.) to X and Y axes for phase wizardry. |\n| `D` | Preset Cycle | Cycle through the curated Split Mode presets (see below) |\n| `Left/Right` | Cutoff | Sweep the frequency spectrum |\n\n### Split Mode Recipes\nDifferent filter combinations create entirely different visual geometries. Here are some of our favorites:\n\n| Preset | X Axis | Y Axis | Sweet Spot | Aesthetic |\n|--------|--------|--------|------------|-----------|\n| **Retro** | Lowpass | Highpass | 40-80 Hz | Classic ellipses, warm analog feel |\n| **Flowers** | Bandpass | Allpass | 150-250 Hz | Swirling geometric petals |\n| **Kaleidoscope** | Bandstop | Allpass | 300-800 Hz | Psychedelic mandalas, sharp edges |\n| **Organic** | Lowpass | Bandpass | 100-200 Hz | Soft loops and folding shapes |\n| **Liquid** | Allpass | Highpass | 20-40 Hz | Vector graphics, CRT water |\n| **Complement** | Bandpass | Bandstop | 200-500 Hz | Complementary bands, \"hollow\" sounds | --\u003e\n\n### Test Signal Generator (XY Mode)\n\nBeta controls the oscillator waveform, at high values you will get chaos!\nProtect your ears by turning down the volume.\n\n\u003c!-- | Key | Action |\n|-----|--------|\n| `T` | Toggle Signal | Turn the internal noise machine on/off |\n| `[` / `]` | Frequency | Tune the base pitch |\n| `Shift+[` / `Shift+]` | Detune | Adjust the ratio between X and Y oscillators to control rotation speed |\n\n## Filter Joystick\nCheck the bottom-right corner. This circular pad is your unified control surface for the SVF filter.\n\n```\n            BP (bandpass)\n               ↑\n               |\n    LP ←———— AP ————→ HP\n  (lowpass)  (center)  (highpass)\n               |\n               ↓\n            BR (notch)\n```\n\n- **Angle**: Morphs between filter topologies (smooth crossfading!)\n- **Radius**: Filter intensity (Center = bypass/allpass, Edge = max filter character)\n- **Mouse Wheel**: Cutoff Frequency\n- **Shift + Wheel**: Resonance (Q factor) - careful, it screams! --\u003e\n\n## Drag \u0026 Drop\nIf you drag a WAV file onto the window, it will load and loop.\n\n## DIY build\n\n```bash\ncd build\ncmake ..\ncmake --build . --target Faveworm\n```\n\n## More Cool Stuff\nSee more of my audio projects at https://dfl.github.io/lowenlabs-audio/","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fdfl%2Ffaveworm","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fdfl%2Ffaveworm","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fdfl%2Ffaveworm/lists"}
