這是一個透過 3D 視覺化呈現音響角度與覆蓋的草圖繪製工具。
輸入的音響發散角將作為高頻覆蓋的近似值，並依 Pulkki-VBAP convex-hull 三角化提供 layout 健康度提示。
請注意：這個工具不能取代聲學模擬，不預測 SPL、頻率響應、反射或相位，也不模擬任何 renderer 行為。
它只回答兩個問題：
- 「我設想的聽覺中心，真的有被我擺放的音響涵蓋嗎？」
- 「我的多聲道 layout 從幾何上看，對 VBAP 系列 panner 是健康的嗎？」
聽覺判斷仍仰賴 renderer 與你的雙耳。
This is a geometric aiming & coverage sketch tool.
It uses your speaker dispersion angles as an approximation of high-frequency coverage,
and provides layout-health hints based on Pulkki-VBAP convex-hull triangulation.
It does not replace acoustic simulation. It does not predict SPL,
frequency response, reflections, or phase. It does not model any renderer's behaviour.
It only answers two questions:
- "Is my imagined listening centre actually covered by the speakers I've placed?"
- "Geometrically, is my multichannel layout healthy for VBAP-family panners?"
Auditory judgement still belongs to your renderer and your ears.
