## 按场景推荐搭配
### 💻 Terminal 交互演示
```
type (0.5s) → enter (0.5s) → command-execute (0.5s) → output-appear (0.6s)
```
循环元素:`cursor-blink` 作为 idle 时的环境音。
### 🃏 卡片选择流程
```
hover-subtle (0.5s, UI悬停) → click-soft (0.5s, 点击) → card-snap (0.5s, 定位)
```
或进阶版:`card-flip` 做前后面切换。
### 🤖 AI 生成全流程
```
generate-start (0.8s, 启动) → ai-process (1.2s, 处理) → sparkle (0.8s, 闪现) → complete-done (0.8s, 完成)
```
错误时用 `error-tone` 替代 `complete-done`
### 🎬 Logo Reveal品牌时刻
```
whoosh-fast (0.6s, 铺垫) → logo-reveal-v2 (1.5s, 落点) → sparkle (0.8s, 尾韵)
```
简版:`whoosh → logo-reveal`(直接 v7b 两件套)。
### 📱 UI 交互演示(移动端)
```
tap-finger (0.5s, 点击) → slide-in (0.6s, 面板滑入) → toggle-on (0.5s, 开关)
```
完成后:`success-chime``notification-pop`
### 📊 数据可视化/仪表盘
```
loading-tick (0.5s, 节拍) × N → complete-done (0.8s, 数据到位) → achievement (1.5s, 惊艳落点)
```
### 🎯 表单提交流程
```
click-soft (0.5s) → loading-tick ×2 (1.0s) → success-chime (1.0s)
```
失败分支:`error-tone (0.7s)`
### 🪄 Magic Transform 场景
```
whoosh-fast (0.6s) → transform (1.0s) → sparkle (0.8s)
```
适合:元素变形、效果前后对比、"AI 重写"等演示。

## 使用规范
### 音量建议(来自 apple-gallery-showcase.md 音频双轨制)
- **SFX 主轨**`1.0`(不做衰减)
- **BGM 背景轨**`0.4 ~ 0.5`SFX 明显穿透)
- **多 SFX 叠加**:用 `amix=inputs=N:duration=longest:normalize=0` 保留动态范围
### ffmpeg 拼接模板
```bash
# 单 SFX 对齐时间点:
ffmpeg -i video.mp4 -itsoffset 2.5 -i sfx/ui/click.mp3 \
-filter_complex "[0:a][1:a]amix=inputs=2:duration=longest:normalize=0[a]" \
-map 0:v -map "[a]" output.mp4
# 多 SFX + BGM
ffmpeg -i video.mp4 \
-itsoffset 1.0 -i sfx/transition/whoosh-fast.mp3 \
-itsoffset 1.6 -i sfx/impact/logo-reveal-v2.mp3 \
-i bgm.mp3 \
-filter_complex "[3:a]volume=0.4[bgm];[0:a][1:a][2:a][bgm]amix=inputs=4:normalize=0[a]" \
-map 0:v -map "[a]" output.mp4
```
### 选型决策树
1. **有 tactile 动作**(打字/点击/滑动)→ `keyboard/` or `ui/`
2. **元素进场/出场**`transition/`
3. **容器层操作**(卡片/模态) → `container/`
4. **状态反馈**(成功/失败/通知) → `feedback/`
5. **进度/时间流逝**`progress/`
6. **品牌落点/重要时刻**`impact/`
7. **AI 魔法/变换**`magic/`
8. **命令行/代码演示**`terminal/`
### 避免叠音堆积
- 同一个时间点 `max 2 个 SFX` 并发
- BGM 降到 0.3 以下时可以放 3 个
- 品牌 impact 时清空其他 SFX留空 0.2s 再落点)

## Prompt 撰写原则(供复用)
参考风格:`apple keynote, tight, minimal, no reverb unless ambient, crisp, elegant`
**好 prompt 的三要素**
1. **声音物理描述**:什么物体、什么动作("mechanical keyboard single key press"
2. **质感/风格限定**apple-style / ios-style / cinematic / retro
3. **反例排除**no reverb / clean studio / minimal
❌ "click sound"
✅ "crisp ui button click, clean modern interface sound, apple-style, high pitched"
❌ "magic"
✅ "bright twinkling stars sound, high pitched glittery chime, fairy dust"
