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-chimenotification-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

  • SFX 主轨1.0(不做衰减)
  • BGM 背景轨0.4 ~ 0.5SFX 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

# 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"
