示例 - 品牌广告 BGM：
ambient, atmospheric, corporate, peaceful, piano, strings,
reverb-heavy, minimal, uplifting, hopeful, Max Richter style,
no drums, 60-second loop
示例 - MV 主题曲：
cinematic, epic orchestral, dramatic build, brass fanfares,
string section, Hans Zimmer style, emotional crescendo,
triumphant, 90-second arc, trailer music
示例 - 抖音 BGM：
upbeat electronic, energetic, synth pop, driving beat,
catchy, modern, chart-topping, 120 BPM, drop ready
3.2 Seedance Audio 提示词
风格: [中文风格描述]
节奏: [BPM]
情绪: [情绪关键词]
乐器: [主要乐器]
特殊要求: [渐入/渐出/循环等]
Step 4: 流媒体响度标准
4.1 平台标准
| 平台 | 目标 LUFS | True Peak | 备注 |
|---|---|---|---|
| 抖音 | -14 LUFS | -1.0 dBTP | 平台会自动归一化 |
| B站 | -14 LUFS | -1.0 dBTP | 与抖音一致 |
| 微博 | -14 LUFS | -1.0 dBTP | 短视频标准 |
| YouTube | -13 to -15 LUFS | -1.0 dBTP | 自动归一化到 -14 |
| Spotify | -14 LUFS | -1.0 dBTP | 流媒体标准 |
4.2 内容类型标准
| 内容类型 | 目标 LUFS | 动态范围 | 说明 |
|---|---|---|---|
| 品牌广告 | -16 to -18 LUFS | 高 | 需要更大动态，保留情感起伏 |
| 短视频 BGM | -14 LUFS | 中 | 平台标准，保证响度一致 |
| MV/电影配乐 | -14 to -16 LUFS | 高 | 保持艺术完整性 |
| 播客/旁白 | -16 LUFS | 低 | 人声为主，音乐为辅 |
4.3 Loudness 概念
LUFS = Loudness Units Full Scale
- 测量感知响度，不是峰值
- 平台归一化后，-14 LUFS 的内容听感一致
- 过响会被压低，损失动态
- 过轻会被提升，可能引入噪声
Step 5: 质量控制检查清单
5.1 生成前检查
- 确认视频时长（5s/15s/30s/60s/3min）
- 确认情绪基调（参考 Step 1）
- 确认目标平台（抖音/B站/微博）
- 确认是否需要循环（广告通常需要循环）
5.2 生成后检查
- 时长检查：音乐时长是否匹配视频？（允许 ±2s）
- 响度检查：使用 LUFS meter 测量是否为 -14 LUFS ± 0.5
- 峰值检查：True Peak 是否 < -1.0 dBTP？（防止削波）
- 循环点检查：如果需要循环，起始和结束是否衔接自然？
- 淡入淡出：开头和结尾是否有适当淡入淡出？（0.5-1s）
- 人声污染检查：BGM 是否有人声？是否干扰旁白？
5.3 问题诊断
| 问题 | 原因 | 解决方案 |
|---|---|---|
| 听起来"闷" | 低频过多 | 减少 Sub Bass (20-60 Hz) |
| 听起来"薄" | 缺少中低频 | 增加 Piano/Guitar 中频 |
| 人声被掩盖 | BGM 太响 | 降低 BGM 响度至 -18 LUFS |
| 循环不自然 | 起始/结束不匹配 | 重新生成或手动编辑 |
| 动态被压扁 | 过度压缩 | 重新母带处理 |
