The main window's built-in visualization area (76×16 pixels in Winamp coordinates) supports eleven display modes. For per-mode shader/algorithm internals see gpu-vis-modes.
| Mode | Description |
|---|---|
| Off | No main-window visualization; leaves the skin's prepared display artwork visible |
| Classic | Low-fi 19-bar spectrum analyzer with skin colors and cropped analyzer sub curve (default; persisted internally as Spectrum) |
| Enhanced | Compact professional LED analyzer with cropped sub range, clean peak caps, and restrained meter colors |
| Ultra | Dense professional spectrum analyzer with cropped sub range, fast decay, clean peak caps, and restrained meter colors |
| Fire | GPU flame simulation using Metal compute shaders |
| JWST | Deep space flythrough with 3D star field and JWST diffraction flares |
| Lightning | GPU lightning storm with fractal bolts mapped to spectrum peaks |
| Matrix | Falling digital rain with procedural glyphs mapped to spectrum bands |
| Snow | Audio-reactive snowfall with flurry-to-blizzard intensity and bass-driven wind gusts |
| EKG | Oscilloscope-style ECG monitor; each detected audio peak fires one QRS, height scales with peak prominence (no BPM clock) |
| vis_classic | Exact-port vis_classic analyzer core with profile-compatible rendering (see vis-classic-guide) |
